L-Band Over Fiber Satellite RF Transport (Transmitter-Receiver)

L-Band Over Fiber Satellite  RF Transport  (Transmitter-Receiver)

The L-Band Transmitter/Receiver pair is used for transporting 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 over fiber this range can be extended to over 75 miles.  Fiber optic cables are much smaller and easier to work with than traditional copper coax.  Additionally our units provide 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.  We Offer CWDM multiplexing solutions for transporting up to 16 distinct L-Band signals over fiber.   We offer single fiber solutions as well as multiple fibers.  We also offer multicasting solutions over several different fibers via optical coupling.  Custom solutions are available; contact us today for help with your specific L-Band over fiber needs.  We are able to design and implement solutions for custom applications.
