C/X-Band Fiber Optic Link: Uplink
The OFW-7820 C/X-Band fiber optic interfacility link (IFL) subsystem provides exceptional gain flatness and phase linearity performance over a 4 GHz instantaneous bandwidth, centered within the X-Band frequency rage.
The OFW-7820 subsystem is part of an integrated earth terminal design intended to transmit and broadcast C/X-Band signal traffic using single mode fiber optic cabling over distances of up to 100 km. These signals can either be direct X-Band SATCOM or IF frequencies being upconverted into the Ka-Band spectrum.
The OFW-7820 utilizes field proven RF optical conversion techniques that are transparent to the various earth terminal modulation techniques and their corresponding data rates. The RF performance of the subsystem is optimized to provide a Spur Free Dynamic Range (SFDR) in excess of 110 dB*Hz(2/3) over a broad range of optical loss budgets.
The OFW-7820 embedded Ethernet capability supports remote control of system parameters such as AGC enable/disable, Manual Gain Control (MGC) set point, and the monitoring of health parameters such as optical power, bias currents, and internal temperature.
The OFW-7820 series can be packaged in various styles of form factors including a 1RU x 19” rack chassis, 4RU x 19” high-density plug-in card chassis, rugged outdoor enclosures, and a compact flange mount unit.
