Thor Fiber Satellite L-Band RF Over Fiber Transmitter and Receiver kit

Model # F-Lband-Tx/Rx

The L-Band fiber optic Transmitter/Receiver pair are used for transporting RF Satellite signals in the L Band over fiber from the antenna to the satellite receiver. L-band RF signals have a very limited range over coaxial cable, typically no more than a few hundred feet. By transporting the L-Band RF signal over an optical fiber this range can be extended to over 50 miles. Fiber optic cables are much smaller and easier to work with than traditional copper coax. Additionally our units provides optional 13/18V LNB power as well as Automatic Gain Control (AGC) to manage RF input level. Fiber optic transport of satellite signals is useful in many applications, such as transportation of signals from a remote satellite farm to a broadcaster's headend, uplink and downlink applications, and DBS services. This fiber satellite (SAT) extender can even transport broadband CATV RF over fiber optic cable. Thor Offers CWDM multiplexing solutions for transportation of up to 8 distinct L-Band signals over a single fiber, as well as multicasting solutions over several different fibers via optical coupling. Custom solutions are available, contact Thor today for help with your specific  L Band  DBS  satellite RF Dish LNB over fiber needs.

Features

  • Low cost kit to transport L-Band frequencies from LNB's over fiber
  • Can provide LNB power at 13/18 VDC over coax
  • Can provide 22 kHz control tone for LNB polarity shifting
  • Can be used to remote satellite antennas up to 10 miles away
  • Compatible with PLC optical splitters, point to multi-point
  • DTH over fiber
  • Grate solution for VSAT network
  • The transmitter receiver Kit comes with 110-220V AC to DC power supply

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.

satellite antenna signal over fiber extender, DBS L BAND over Fiber Tx+Rx Basic 1 Ch Kit
SATCOM DBS Fiber Optic Transmitter Receiver kit, RFoF, converts satellite RF signal form LNB coax to fiber optic signal and from fiber to back to Sattelite RF. it works as a Coax but over the fiber, single-mode fiber is needed with SC/APC angle polished connectors. Coax cable has its own distance limitation, by using this converter you can send modulated RF 54-3000Mhz over fiber up to 20KM. This unit could be also used for ATSC over fiber or CAble TV RF over fiber because of the wide RF range supported this is the link:: https://thorbroadcast.com/product/l-band-over-fiber-tx-rx-basic-1-ch-kit.html in spanish El kit de receptor de transmisor de fibra óptica SATCOM DBS, RFoF, convierte la señal de RF satelital de coaxial LNB a señal de fibra óptica y de fibra a RF de satélite. funciona como un cable coaxial, pero a través de la fibra, se necesita fibra monomodo con conectores pulidos en ángulo SC / APC. El cable coaxial tiene su propia limitación de distancia, al usar este convertidor puede enviar RF modulada 54-3000Mhz sobre fibra de hasta 20KM. Esta unidad también podría usarse para ATSC sobre fibra o TV por cable RF sobre fibra debido al amplio rango de RF admitido Este es el enlace:: https://thorbroadcast.com/es/producto/banda-l-largo-de-la-fibra-tx-rx-basica-1-ch-8230.html

Question and Answers

Answer:
Generally yes, but there is several different options. How many LNB's does your dish has? Please give us call directly we will explain as different providers have different hardware options; we just need to match the hardware that you have to the hardware we offer to create a seamless transition of your Dish service
Answer:
Yes, you can use our L-band over fiber TX/RX, it should work even if you have a 50ohm interface. If you must have 50ohm, we have GPS over fiber TX RX available with 50ohm TNT RF connector, it will cover 470 MHz-952 MHz https://thorbroadcast.com/product/gps-over-fiber-reference-timing-fiber-optic-waterproof-solution.html
Answer:
If the dish you have has a built-in SWM; then there is nothing we can do to help. We have transmitter and receiver kits that convert the LNB's to fiber; however, these units must go in between the dish and the SWM , because there is bi-directional communication between STB's coxes and SWM You can go purchase your own dish without the built-in SWM; depending on the model you choose, our LB41 systems and the LB61 Systems would work https://thorbroadcast.com/product/6-ch-l-band-over-single-fiber-extender-54-3000mhz-cwdm.html
Answer:
Yes this unit F-LBAND-TX/RX supports 50-2800Mhz RF input.
The ATSC spectrum RF is between 50-800 MHZ, the satellite L'Band is between 850-2100Mhz 
Using this TX and RX you can send both signals.
You can simply combine the signal from the dish and from the residential antenna using smile 1x2 splitter/combiner
 
If there is short distance than Coax is a better and less expensive choice 
It is great for sending signals from the Dish or ATSC or both for long-distance, let's say that some residence doesn't want to have a big dish next to the house, or skyscraper needs to send the signal to the master headend located in the basement.
Standard TX/RX supports up to 20Km of fiber.
 
Yes we can send you 200-300 feet of fiber with the TX/RX .
 
Please note this unit is able to extend1 LNB,  some satellite services like Direct TV uses multiple LNB's , in this case we have different units 4 or 6 LNB over 1 fiber extender.
those units actually convert every LNB input on separate light wavelengths ( colors of light ) and internally passively combine them , receiver separate the light using filters and convert it back to the original Lband RF (it gets complex) 
 
those are the links :
 
 
Answer:

s the application just point to point? Is the CATV QAM or ATSC?

Does the customer have Single mode fiber in place with SC/APC connectors?
What is the approximate distance of the fiber? Or do you know the optical budget/loss?
We have an abundance of products for this kind of application.
Transmitter and receivers are readily available and in stock, just need to a know a little bit more information so we can point you in the right direction.
Answer:
 
Sirius satellites broadcast within the s-band frequencies from 2.3200–2.3325 Ghz , while XM radio uses adjacent frequencies 2.3325–2.3450 GHz.
So a few things here, realistically it should work then. 
A Couple of options or things to consider is, does the XM antenna require power/voltage to the antenna?
Does the antenna require bidirectional communication?
 
The other options we have are 
Trying the new set 
Again, updated specs and it could possibly work, even though its the same frequency range. 
 
Another option is to go up a level and try these:
If you look in the description it's made for S BAND
 It is used in many RF over fiber applications like communications, defense systems, satellite L-band, S-band, GPS, WiMAX, cellular 3G, 4G and LTE signals.  
 
 
These articles goes over more stuff
  • Satellite radio: 2.31 to 2.36 GHz
 
 
Answer:
We have a few different options to choose from. 
We have individual sets in compact format 
 
Depending on the voltage of those 2 Lbands you could possibly use this set:
 
For the 9 Antenna's we have 6 Channel Mux units available 
 
Please let me know if you have any questions or would like a formal quote. 
If you would like more information or would like to discuss you can reach us at 1800-521-8467 ext 2
 
Please note all of our LBAND equipment requires singlemode fiber and is terminated with SC/APC connectors. 
Answer:

 

We have two kinds of systems of Lband, compact and rackmount. The rackmount systems all use CWDM and have either 4 or 6 LNB inputs. 
The compact units are single units with one LNB. 
All of these units can power the LNB from the transmitter. 
Answer:
Yes, absolutely, we know for a fact that many companies are using them in conjunction with Dish services in MDUs.
If you have some specific applications, please describe them, we have a wide product range, and we can manage most applications over Fiber, over IP network, RF or ASI.
 
There are some examples
QAM modulators :
 
1 HDMI IN - QAM CATV TV Out
 
1-8 HDMI IN - QAM CATV TV Out
 
IP IN - QAM CATV TV Out
 
DVBS/s2  satellite   RF decoders :
 
16 DVBS/s2 satellite   RF to IP gateways : .
 
 
 
Multi-channel IP HDMI or SDI encoders - up to 24ch
 
 
Please let me know if there is anything you would be potentially interested in any of these.
Answer:
That's correct, we do not offer it, because it's impossible to put RF on multimode fiber. 
If you would like to use HDMI over Fiber for a very short distance on multimode, we do have a solution for that. 
Cost for the transmitter and receiver is $495.00 and does come with accessories like power supplies and Red Eye. 
Let me know if that will work for you. 
Answer:
We do have a perfect L-band over fiber TX/RX solution in a few different form factors.
 
We can offer the following units:
 
1)
 F-LBAND-TX/RX  ( transmitter / receiver kit + power supply )
 
 
 
 
 
2)
We do have also 2ch or 4ch portable units :
F-SattGalaxy-TX/RX-3, F-SattGalaxy-TX/RX-5
 
 
 
3)
4 channel and 6 channel Rackmountable - over single fiber
F-LB41-CWDM-TxRx - 4ch
 
F-LB61-CWDM-TxRx  - 6ch
 
 
 
Please review and let me know if any of that unit would work for you.
Answer:

I'd be happy to clarify how we can extend Direct TV signals using our Lband  Fiber Optic extenders products.

Direct TV usually has four or more LNBs, which are connected directly via four or more coax cables into the SWM. The SWM has RF output/input and communicates with the STBs in both directions. Since fiber optic is strictly unidirectional, we can only extend the 4/6 LNBs' signal into the SWMs, not from SWIM's to set-top boxes. ( so we can not use F-LBAND-TX/RX from your splitter MSPLIT8R1-03 )

The easiest way to help you with your application would be to use the F-LB41-TX 4 L-band Transmitter (4 LNB fiber optic extender with a 1x4 Optical Splitter and three F-LB41-RX receivers. These receivers would be connected to three SWMs where you can run your 1x splitters and set-top boxes. Please check the link below for a drawing to visualize your application:

 

If your Direct TV has more than four LNBs, please consider the LB61.


Our units requires single mode fiber and SC/APC connectors, if you have LC/PC than you will need to use LC/PC to SC/PC optical jumpers on each end of the fiber

Please let me know if this is clear.

Answer:
Thank you for your inquiry regarding our RF over fiber solutions. We specialize in "Fiber Brake" RF to Fiber equipment and have extensive experience working with DoD, military, and government agencies.
 
We have several options available for your application. 
The main question is what satellite service you are using and how many LNBs you need to convert to fiber. For example, DirecTV typically has 4 to 6 LNB dishes.
 
Please check the link below for more information on our L-band satellite RF to fiber extenders:

Answer:

Thank you for reaching out. Yes, this is correct—the Fps over fiber devices work as a transmitter and receiver pair. The F-4GPS-TX-WE is an optical transmitter only, converting the RF GPS electrical signal into an optical output. The F-LBAND-TX/RX is a receiver only, which converts the optical signal back to the original electrical GPS RF signal. Therefore, the device functions as a GPS RF extender over fiber and, importantly, acts as a Physical Isolator. We refer to this as a "fiber break" because it creates an inability to send any signals back from the RX to the TX. The RX is not equipped with any laser; it is just an optical detector.

If you only need one GPS, here is the link to the F-1GPS-TX/RX, which will get the job done. Please note that we also have a very similar solution for Satellite Antenna L-band over fiber (F-LBAND-TX/RX) and for Cable TV RF with a fiber break. These devices are essentially rated for different RF frequency ranges.

If you only need one GPS, here is the link to the F-1GPS-TX/RX, which will do the job.
 
 
Please note that we also have very similar solutions for Satellite Antenna L-band over fiber 
(F-LBAND-TX/RX)
 
 and 
 
Cable TV RF cable (fiber break). They are essentially rated for different RF frequency ranges.
 
In your application, which signal would you like to isolate: GPS, L-band, or CATV RF cable?
