Foxcom Sat-Light C-Band Tx/RX Fiberoptic Interfacility Links
Optical C-Band transmit and receive from 3.4 to 6.8 GHz, fully transparent link
C-Band Tx/RX Fiberoptic Interfacility Links
Foxcom’s Sat-Light C-Band fiberoptic interfacility links transmit and receive uplink and downlink signals in the 3.4 to 6.8 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.
Fully Transparent
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 these high efficiency, low noise
analog links.
Overview
A typical C-Band link consists of an optical transmitter, which receives the RF signal, transmitting it over singlemode fiber to an
optical receiver which 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 C-Band’s link state of
the art lasers produce negligible chirp and optical distortion; critical for long distance links. The links are
provided with test ports, status and fault LEDs, and gain controls.
