Sat-Light C-Band fiber optic interfacility links transmit and receive downlink signals in the 3.4─4.2 GHz range between antennas and control rooms or NOCs. Global Foxcom’s IFLs offer a high performance alternative to conventional coaxial-cabled systems, reducing the need for wave-guide 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 fiber optic connections to provide the highest levels in signal quality. Global Foxcom achieves this by using state of the art lasers to provide high efficiency, low noise analog links.
A typical C-Band link consists of an optical transmitter that receives the RF signal, transmits it over a single mode fiber (RFoF) to an optical receiver and reconverts the optical signal to RF. Global Foxcom’s advanced fiber optic 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 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.
