Question 1

I built a small cabin on a lake and am trying to get Dish Network television. The problem is that 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 away, 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, that 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 am just trying to find a way to get television reception at the cabin.

Accepted 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 farther away from the receiver than 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 LNBs. 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 weatherproofing you'll need, along with some sort of power supply up to the dish so you can power the Transmitter and the dish's LNBs. 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 2

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.

Accepted Answer

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

Question 3

We're a DirecTV MDU Dealer. I am looking for a more cost-effective solution than the FiberSync system by P10 PerfectVision, as I am looking for an alternative source. 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.

Accepted 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 4

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, 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 user's 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 your 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 an 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 of how this all interconnects to show all involved how this would all fit together....

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

Question 5

1) We need a minimum of 3 L-band signals sent over fiber to a TOC. Fiber distance is estimated to be no more than 1000' for 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.

Accepted 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 of the Tx units will require a power supply.

Question 6

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

Accepted Answer

We do have the equipment to send DirecTV over fiber. However, much like CATV or any DISH in the RF world, it can only be sent over fiber using single-mode fiber. 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 7

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

Accepted Answer

It's a direct TV signal. The component we spec'd originally was Blonder Tongue and had an RF frequency of 250-3500 MHz. It is no longer available. How many LNBs 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 L-band 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 900 MHz. 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 L-band it is not Are you able to explain a little more? CATV is 5-870 MHz and L-band is above 1 GHz to 2.4 GHz 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 52-2.47 GHz 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 LNBs 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 the 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 spec'd 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, I'll take a look But the Blonder Tongue guy wasn't talking LNBs. 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 you're just learning the hardware, but the good news is that installation with our units is a breeze.

Question 8

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 what the ETA would be if we ordered. 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

Accepted 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 9

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

Accepted 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 service independent. You can use any signal from any satellite 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 the SNMP and WEB option. The TX has an SC/APC angle-polished connector, and only SC/APC fiber connectors should be used. By using standard blue SC/PC fiber jumpers can damage the devices. Therefore, make sure to interface the device only with SC/APC-terminated fibers or 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 whatever comes in on the TX goes out on the RX.

Question 10

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, with 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 through 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 cables running between the equipment enclosure and the production facility are 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; we 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 an 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.

Accepted 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) The 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 this: 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, and 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 11

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 the 4th receiver will be used as a spare unit. Please confirm if that would work.

Accepted Answer

Yes, this configuration fits your project perfectly: Direct TC LNB KA\KU Slim Line Dish/Antenna (SL5 Model) located on the roof of the building, but Sonara 5SATPL Power Inserter and Polarity Locker is not necessary to use, since we are generating LBV voltage and 22 kHz 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 also not be needed, since we can accept incoming signal at 85 dBuV RF power. (Off-Air) Lava HD-2605 Outdoor Antenna-UHF/VHF/FM/SDTV/HDTV is a good choice.

Question 12

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 about the SC/APC connectors and fiber budget.

Accepted 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 LNBs. 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 20 km, 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 13

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 the 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.

Accepted Answer

For the 4 LNB transmitter for the DIRECTV dish, is it 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 https://thorbroadcast.com/product/4-ch-l-band-satellite-over-single-fiber-extender-transmitter-and-8230.html
