Description

Fiber Optic 6 LNB to SWM Switch Extender System for 6 Polarity Satellite TV

The F-LB61 system from Thor Fiber is designed for use with satellite TV systems that have six LNB coax cables coming from the antennas. These are typically systems that support an additional antenna used for international content or free to air programming. The LB61 solution will work with most standard satellite TV antennas such as Directv® and Dish Network® systems. LB61 creates a fiber optic link between the satellite antenna and the single wire multiswitch portion of the TV system. This can be used to overcome distance limitations between the antenna and the rest of the system, or to distribute the output from a single antenna to multiple TV distribution locations. The standard LB61 system can be used to deliver the output from a satellite antenna to up to 32 individual optical receivers. The output from each of these optical receivers is identical to the output from the original satellite antenna. There is no way that the equipment from the television provider can detect that it is not directly connected to its own satellite antenna.

The most common application for the LB61 system is extending the maximum distance between a television system and its satellite dish antenna. Without the use of a Thor system, the satellite antenna must be installed within 100 meters of a multiswitch or receiver equipment. This is not a problem for most residential or household type consumer applications; but presents a significant obstacle in larger high rise buildings or corporate installations. The LB61 system increases the flexibility of satellite TV systems by overcoming the distance limitation between the antenna and the rest of the TV system.

Question and Answers

Question:
I built a small cabin on a lake and trying to get dish network television. The problem is the cabin sits very low down a hill. There are many trees and when dish installers came out to look they said I would have to cut trees in order to get a signal. Obviously I don't want to do this. My house is up the hill about 450 feet and I have dish television there. If I can put the dish closer to my house where I can get a line of sight to satellites and run a cable down the hill to the television would be good. Is this possible? If so what would I need to make it work? Would a normal dish network dish work? Would RG-11 cable work at that length? Or would something else be better? As you can tell I have no experience in this and just trying to find a way to get television reception at the cabin.

Answer:
So this is all relative to what kind of Dish you have. Our Lband over Fiber systems assist contractors and integrators in moving dishes further away from the receiver then the allotted RG coax allows which is roughly 90 feet. So if you can't use good old copper, most professionals have to install singlemode fiber, which will carry the signal for miles. In this case you'd be looking at a fairly expensive endeavour based on the dish you have. Some old style dishes have a single LNB polarity; most new HD dishes have anywhere from 3-5 LNB's. What our systems do is take those polarities, convert them to glass via CWDM multiplexing, and then the reverse happens on the receiving end. This does not include the Fiber, The Dish, or the Outdoor weatherproofind you'll need along with send some sort of power supply up to the dish so you can power the Transmitter and the Dish's LNB's. So if you know the model of the dish you have let us know and we can point you to a specific model. Feel free to reach out if you have any other questions.

Question:
We're looking for equipment that can convert from L-Band to IP and then from IP to L-Band to extend some LNB signals.The fiber option doesn't work for us as we can't deploy it, we can only use wireless IP links

Answer:
we have a unit that would work for you but it will not take entire L-band, it has 16 individual L-band channels input, the programming needs to be unencrypted.Please check this link below, and let me know if it will work for you, if you more channels, you can use multiple units and. Each band channel can carry multiple TS programs.Each TS's is being converted to its own multicast or unicast UDP stream https://thorbroadcast.com/product/16-rf-tuners-to-iptv-ts-qam-output.html/118

Question:
We're a DirecTV MDU Dealer. I am looking for a more cost-effective solution than the FiberSync system by P10 PerfectVision as I'm looking for an alternative sources. I am looking to get pricing and assistance in finding a solution that does all the DirecTV Bands in an MDU deployment over a single fiber strand.

Answer:
We have 1,4,6 LNB's over fiber available. The LB61-CWDM unit has 6 individual lasers converting each LNB to its own CWDM wavelengths, this is how we can multiplex 6 individual RF signals over 1 single fiber. The Transmitter and Receiver are 19" rack-mount 1RU chassis', the unit has LCD display it shows RF input and output power as well as the Optical input and output power, making it very easy to install without specialized testing equipment. In addition, each input on the Transmitter can be set to output 13V, 18V, 0V with 22khz tone, so a polarity locker is not needed. The standard Transmitter can be split 1x8 using external optical coupler F-PLC-1x8 to connect 8 remote locations.

Question:
Tks for the quick response…. I have talked with the user and have some additional information…I will also attempt to explain our exact needs….. Our configuration…… (1) Direct HD Dish on roof w/4 rg6 cables from LNB…the which penetrate roof (2) The 4 rg6 cables connect to a HD multi switch…but will need a new HD multi switch…the one we have is a home users borrowed one. (3) 2 outputs of multi switch go to 2 recvrs OUTSIDE of SCIF area to managers offices. This ends the HD feed due to our current fiber option for SD will not work with HD. I reinstalled a second dish (SD) (our old configuration before HD upgrade) and took the 2 rg6 outputs from LNB to (2) F-LB41-TX fiber optic transmitters…which penetrate into SCIF area. (FIBER run approx. 20ft – 30ft.) (4) In SCIF area the 2 fibers go into 2 fiber optic receivers. Out of receivers via rg6 to a splitter to the 2 Recvrs. This works pretty well for SD but will require a whole new system for HD, which prompted my call to THOR. (5) Since talking to you engineer…I have found an additional requirement…… (6) There will be an additional DIRECTV HD feed from another satellite dish which will go to a different part of our organization (same bldg. just down the hall) and via a HD multi switch an output will come over to my part of the bldg. via a single rg6 cable for insertion into my SCIF…So I have another issue with this HD rg6 feed…..How do I incorporate that into our fiber solution….We can possibly have them send this over via another means if required…i.e…fiber..I would have to get your input on how to accomplish this second feed….. I would like to build in a small room for growth say and additional 3 or 4 receivers but probably no more than that..or at least at a later date be able to add on. But what I need after review of this email and any questions you might have….I would like a detailed list of equipment needed and pricing and ordering info….if possible a simple diagram how this all interconnects to show all involved how this would all fit together……

Answer:
Please check this drawing, it shows connection diagram : https://thorbroadcast.com/upload/files/177/satellite-tv-fiberbreak.pdf

Question:
1) We need Minimum 3 L-Band signals sent over fiber to a TOC. Fiber distance estimated to be no more than 1000' as of this request, but this could change. There will be a weatherproof enclosure with a cooling fan at the antenna location. 2) This looks great. However, can you package this so the transmit side has 3 individual transmitters and the receiving end is rack-mounted? I don’t believe I’ll have the real estate to rack mount a transmitter in the NEMA box outside near the antennas.

Answer:
1) The best option for this application is to use our LB41-CWDM system which can take up to 4 L-band signals and will mux them onto one fiber. https://thorbroadcast.com/product/4-ch-l-band-over-single-fiber-extender-45-3000mhz-cwdm.html 2) So, in this case, you would need to use 3 separate portable transmitters and receivers running over 3 separate fibers: This is the link : F-L-band-TxRx https://thorbroadcast.com/product/l-band-over-fiber-tx-rx-basic-1-ch-kit.html Each kit has a transmitter, receiver and power supplies. These are quite compact and should be able to fit 3 of those in the Nema box easily, but each one of the Tx units will require a power supply.

Question:

I am trying to extend a DirecTV or Dish Network feed over multimode fiber, do you have something that would work?

Answer:

We do have the equipment to send DirecTV over Fiber.

However, much like CATV or any DISH in the RF world, can only be sent over fiber using a single mode.

There are no systems in the world available that will let you send any band of RF over multimode fiber.

https://thorbroadcast.com/product/4-ch-l-band-over-single-fiber-extender-45-3000mhz-cwdm.html

Question:

I'm looking for a piece of equipment to send a broadband fiber signal over fiber 1700ft.

Answer:

It's a direct TV signal. The component we spec'd originally was blonder tongue and had RF frequency of 250-3500 MHz.

It is and no longer available.

How many LNB's did that system have?

1, i believe. i see a 4 channel unit

4 Ch L-Band Over single Fiber Extender 45-3000Mhz -CWDM

We do have single Lband sets

I'd like to see those.

https://thorbroadcast.com/product/l-band-over-fiber-tx-rx-basic-1-ch-kit.html

that starts at 900MHZ. I don't know enough about RF to know if that is important or not.

But it looks perfect otherwise.

I see the DirecTV sat dish.

For lband it is not

are you able to explain a little more?

CATV is 5-870mhz and Lband is above 1ghz to 2.4ghz

and our band units are wide band, if you read down a little further, they are wide band to include ATSC as well

so realistically those units work from 52-2.47ghz

But DISH works in the spectrum above CATV

DirecTV?

What you should check is to see if your DISH has a built-in SWM and that is the reason it's only outputting one LNB so to speak

because that means the polarities are stacked, and the unit won't work. But if it's a bit of an older dish and ONLY has one LNB, then you should be fine

I'm not sure of the one LNB answer

hence why we offer the 4-6 LNB input systems, modern HD dishes usually have at the minimum 4 polarities, which means 4 LNB's

argh. existing Directv client getting moved.

so the 4 unit model is the right one? How much for Transmitter/Receiver? List?

I can't tell you which is the right one because we don't have enough information to dictate that.

Some dishes can have one LNB, or 2 or 5 or 6, it varies quite a bit

gotcha

RF only works on singlemode fiber and requires SC/APC connectors

perfect. that is super helpful,

We essentially have all the options, we just need to know specifics of the hardware you have, then we can point you in the right direction

how is availability?

all are in stock

perfect, I'll find out more info and select the right one

sounds good!

If you could get us the model number that was specd by blonder we could also work off of that as well

Blonder Tongue Part No. FILT-S3A-3000

Blonder Tongue Part No. FILR-S4A-3000

Blonder Tongue Part No. ACCS-PS-170

ok ill take a look

But the Blonder Tongue guy wasn't talking LNB's.

Ah I see

Do each of those put out a cable?

yeah those are single LNB kits

here's my honest opinion, go do some research on the dish, take pictures, look up specs, and then look at the situation again

i have pics of the existing dish, so it should work out fine. thank you

It's a little complicated when just learning the hardware, the good news is an installation with our units is a breeze.

Question:

1) We have a project that has a mountain in the way of our Bell satellite-based TV head end. We are looking at your : https://thorbroadcast.com/product/4-ch-l-band-over-single-fiber-extender-45-3000mhz-cwdm.html and wanted to know what the availability is and if we ordered what the ETA would look like. Additionally, is there another way to do this? We have fiber running to the site, what would we need to put our head-end in our office in Edmonton and send the signal to our camp in the mountains of British Columbia? We have looked at RF over fiber or rg-11.

2) 13 KM is the distance. Will it work with multimode fiber?

Ok, thanks for that, working with a telco to get SM fiber out to my site. Going to mount Bell dish on their colo in the town and send it to my site 13KM away.

If I can get a single mode out to the site, what hardware do I need to connect that dish to my rack of receivers at the site?

https://thorbroadcast.com/product/1-l-band-lnb-dish-over-fiber-extender-with-outdoor-enclosure.html

or

https://thorbroadcast.com/product/4-ch-l-band-over-single-fiber-extender-45-3000mhz-cwdm.html

Answer:

1) What is the distance of the single-mode fiber run you have? Or do you know what the optical loss budget is?

2)

Unfortunately you can not put RF on MM fiber. It just won't work.

Nearly all the products we sell that are compatible with MM fiber are only good for a couple thousand feet.

So sending any signal 13km on MM is not going to work out very well.

In either case, any RF product will necessitate singlemode fiber only. So long as that link that is 13km doesn't have any exaggerated losses in the line, our stock units should be able to work just fine in that environment.

3) for 13KM the F-LB41-CWDM-TX/RX set is sufficient

Question:

Can you give us the procedure/instructions on how to install and commission the equipment F-LB61-CWDM-SNMP-TxRx or F-LB62-CWDM-TX/RX

Answer:

The devices are very easy to install.

The TX has 6 RF inputs from the satellite dishes' LNBs.

You have a choice to power the LNBs from the TX. Each input can have 0V, 13V, 18V, or a 13V+22khz tone to 18V+22Khz tone.

The device is a service independendt, you can use andy signal from any sat company like DirectTV ,Dish network, Bell media, Shaw communications or any free to air service 50-3000Mhz

You can do this using buttons and LCD front panel control or by logging into the web interface using the device's IP address if purchased with SNMP and WEB option

The TX has an SC/APC angle-polished connector and only SC/APC fiber connectors should be used.

By bsing standard blue SC/PC fiber jumpers can damage the devices. Therefore, make sure to interface the device only with SC/APC terminated fibers of optical jumpers on the TX and RX sides.

The receiver also has an SC/APC optical connector and 6 corresponding RF outputs , it is one to one, so that here comes in on the TX , it goes out on the RX

Question:

I am trying to get additional information for model F-LB61. I am configuring a project that would use five or six of the kits. I need to know the product availability

------------------------------

2) The F-LB61 looks to be exactly what we will need. Here is some additional detail on how the equipment will be used.

The system will be comprised of (5) 3.8m antennas each with dual band and dual polarity feeds with individual externally locked PLL LNBs, no need for the 22Khz tone or power. Low loss RG-11 Tri shield cable, Belden 4731R, runs between the LNBs and the equipment enclosure. The maximum run length is 125 feet.

Entry to the enclosure is via surge suppressor. Once inside the enclosure each cable terminates at a dedicated diplexer / bias tee providing 24Vdc and the 10Mhz reference for the LNBs. The L-Band output from the diplexer passes thru a 20dB directional coupler, creating a test port, before terminating at the F-LB61. Low loss RG6 dual shield cable, Belden 4694R, is used for all connections post diplexer.

The (12) single mode fiber cable running between the equipment enclosure and the production facility is approximately 5Km. All fiber terminations are premium SC APC. The final production facility location has not been finalized as of 20230301. However the estimated date of acquisition for the site is May 01 2023. Five F-LB61 transmitters and one F-LB61 receiver will be located in the remote equipment enclosure. The five F-LB61 receivers and one F-BL61 transmitter will be located at the production facility. Inputs / outputs 5 and 6 on each of the F-LB61s will be used for auxiliary IF / RF signals between the locations.

Questions are always welcome and as an independent consulting engineer I will provide as much information as I am allowed under my confidentiality agreement.

A few questions,

        A )What are your standard wavelengths used for the F-LB61? We are flexible, just want to know for planning             our CWDM mapping.

        B)I presume adding the SNMP option, which will be ordered on all units, adds additional wavelengths as it is a             bidirectional service. What are your standard wavelengths for this option?

        C) Have you conducted a MTBF analysis and what is that MTBF figure? This will determine our spares                         requirement.

        D) How flat is the frequency response and what is the group delay across the 54 - 3000Mhz bandwidth and                 any 50Mhz segment?

        E) Lastly, is there a 48Vdc power option available for one of the power supplies? If available, what if any, is             the additional cost? Not a show stopper just a question as we will have a floating nominal 48Vdc buss                 available at both locations.

Answer:

Thank you for reaching out to us. The F-LB61-CWDM-TX/RX is an excellent choice for sending 6 L-band signals over a single fiber.

We utilize 6 individual CWDM lasers for each RF signal.

The transmitter can power an LNB with 13 or 18 or 13/22hz, 18V/22Hz power if needed.

The transmitter and the receiver come with dual redundant power supply. It operates over 1 single-mode fiber with SC/APC connectors.

The Transmitter / Receiver can also have an SNMP option for monitoring

--------------------------------------------------

2)

he LB61 should not have any issues with the setup you will have. If the transmitter receives 90-110dBuv RF input, we will be fine. The TX/RX kit can support up to 20km of fiber, so 5km should not be a problem. Since you will use your own power, the TX will be set to 0V output.

Please find my answers:

A) 1470,1490,1510,1530,1550,1570,1590nm

B) No, it is not tied to the optical transport. The device needs to be connected to the local LAN. However, if you have extra fibers, you can establish an independent 10/100/1000 link between the sides using Ethernet transceivers like that:

F-GET-SFP-TR

https://thorbroadcast.com/product/10-100-1000mbps-fast-and-gigabit-ethernet-fiber-media-converter-with-sfp.html

C) No, unfortunately we did not conduct a study as we do not have enough data. This is a relatively low quantity specialty product, we do not have too many failures or RMAs. I would estimate 1-3% in 3 years

D) The signal is relatively flat, probably 5dB maximum across the entire spectrum

E) So, normally we do not produce them in 48V DC. We could possibly do it, but it would be costly, and we would need to charge an additional fee for it. If you do not require it, I would recommend going with the standard 120-220V AC

-

Question:

I attached a drawing of my solution and what I am looking to do. I would need the transmitter unit, Optical Splitter, and 4 receivers and 4th receiver will be used for a spare unit , please confime if that would work

Answer:

Yes, this configuration and it fit perfectly your project :" Direct TC LNB KA\KU Slim Line
Dish/Antenna (SL5 Model) Located on the roof of the bulding , but Sonara 5SATPL Power Inserter
and Polarity Locker is not nesesary to use, since we are generting LBV volage and 22kh tone

99 & 101 (Even) LHCP requires (18 Volts)
99 & 101 (Odd) RHCP requires (13 Volts)
103 & 119 (Odd) RHCP requires (13 Volts)
103, 110 & 119 (Even) LHCP requires (18 V)

The Tamp-6R03 Trunk Amplifier Input/Output 5 to 2400 MHz might be also not needed , since we can accetp incoming signal at 85dbuv RF power.

(Off-Air) Lava HD-2605 Outdoor Antenna-UHF/VHF/FM/SDTV/HDTV is a good choice.

Question:

Please quote a DirecTV Satellite Fiber Extender.

The fiber run has multiple patch panels and does not have Angled Polished connectors. Is this an issue?

We will add the Fiber Extender after the Polarity Locker and AG Cans before the SWiM. If you have any documentation or notes on typical configurations for DirecTV, that’d be helpful.

Good to know on the SC/APC connectors and fiber budget.

Answer:

We can supply the DirecTV Satellite Fiber Extender. We have a model that should work for you.

The question is do you know how many polarities their satellite has?

In my past experience it's usually 4 or 5 LNB's.

If the dish has a built-in SWM switch then we do not have a way to extend the signal since data is bidirectional after the SWM.

So our models need to go in between the Dish and the SWM.

This is a link to the 4 port model https://thorbroadcast.com/product/4-ch-l-band-satellite-over-single-fiber-extender-transmitter-and-8230.html
All of our RF gear is SC/APC which is industry standard.

If you don't have a meter to check what the optical loss is, it should be fine since these are rated to go about 20km, so you have a bountiful budget

either way.

If you intend to use a polarity locker, then there is really no configuration needed.

Each RF input on the TX will just need to be set to 0V output, since the polarity locking will be handled by the polarity locker.

The corresponding outputs on the RX will need to be plugged into the SWiM switch—and that’s it.

Question:

Can i get some system design help and a quote for materials please?

I have an existing KAKU system and would like to start upgrading to directv over fiber. Can you please advise on the equipment to connect to hte existing dish, with the needed components to distribute the directv signal over fiber.

The existing system is a 4 wire LNB to a 32 port switch. I can add a splitter and whatever other components I need to send the signal. Just let me know.

On the end of the line, I have 30 receivers. Just fyi.

Answer:

For the 4LNB Transmitter for the Directv Dish is a point to point, then the receiver has a SWM after it that's 1x32?

If that's the case then all you need is the F-LB41-CWDM-TxRx model, 4 LNB input over one strand of single fiber
