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.

IMPORTANT NOTE*** (it is very important to interface our unit with SC/APC - Angle Polished Connector to avoid any light reflections.

If your fiber is terminated with the  SC, ST, FC /PC flat connector, you need to use an optical jumper from PC type to SC/APC for proper conversion.

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