F-KuBAND 10.7 to 15 GHz Ku Band Over Fiber RF 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.  When used in CWDM configurations the F-KuBAND is able to transmit up to 8 independent satellite signals over a single fiber.  The F-KUBAND link is a cost effective and high performance solution for KU-Band over fiber Satellite links.
