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
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.

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.
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

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
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.

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.
