F-KUBAND 10.7 to 12.75 GHz RF over Fiber Transmitter and Reciever

F-KUBAND 10.7 to 12.75 GHz RF over Fiber Transmitter and Reciever

The F-KUBAND is used to transmit and receive uplink and downlink signals up to 15 GHz.  This is useful for links in between control rooms or NOCs.  The F-KUBAND system offers a high performance alternative to conventional coaxial link systems, both reducing attenuation and eliminating the need for a waveguide.  The unit functions as a transperent link, transporting all satellite modulation formats over a single fiber.  Typically a KU-Band fiber link consists of an optical transmitter that recieves the RF signal and transmits it over singlmode fiber to an optical reciever which converts the optical signal back to RF.  The F-KUBAND link is a cost effective and high performance solution for KU-Band Satellite links.
