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.
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.

s the application just point to point? Is the CATV QAM or ATSC?
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:
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.
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.
The Thor 20GHz Transmitter is a high performance Lightwave Transmitter Module designed for analog photonics applications from DC to 20 GHz
Waterproof Outdoor GPS fiber optic Transmitter and 19" rack-mountable receiver, sends the signal from a GPS antenna to a receiver over singlemode fiber. The transmitter and receiver has RF and Optical meters, allows quick and seemless implementation without any Optical and RF instruments.
