Summary |
||
Foxcom GL952KD RF Link KU-Band Downlink [13.75-14.5GHz], 3dB Optical Budget Foxcom's Sat-Light KU-Band fiberoptic interfacility links transmit and receive downlink signals in the 10.7-12.75 GHz range between antennas and control rooms or NOCs. Foxcom's IFLs offer a high performance alternative to conventional coaxial-cabled systems, reducing the need for waveguide and minimizing signal attenuation. The Sat-Light IFLs function as a transparent link, transmitting all satellite modulation formats carrying an entire polarization on each link. System limitations in using coaxial cable are overcome by the simplicity and performance of fiberoptic connections to provide the highest levels in signal quality. Foxcom achieves this by using state of the art lasers to provide high efficiency, low noise analog links. A typical KU-Band link consists of an optical transmitter that receives the RF signal, transmits it over a single mode fiber to an optical receiver and reconverts the optical signal to RF. Foxcom's advanced fiberoptic technology reduces the attenuation, slope, phase shift, and group delay maintaining extremely low levels over distances of up to 15 kilometers. The KU-Band's link cost effective high performance lasers produce negligible chirp and optical distortion, which is critical for long distance links. The EAM monolithic design, versus connectorized component electro-optics, assures high performance along with excellent reliability. The links are provided with test ports, status and fault LEDs, and gain controls.
