Transceiver Technology with In-Situ Diagnostic Optical Power Monitoring for Defense Applications

摘要

A transceiver technology with in-situ diagnostic optical power monitoring for defense applications is presented. The transceiver transmits and receives CWDM optical data signals over a single multimode fiber. Multimode fibers are preferred in many defense applications due to their elevated connectorization ruggedness compared to single mode connectors. The transmitter optical subassembly includes an array of vertical cavity surface emitting lasers, each directly modulated at 10.3125 Gbps resulting in aggregate data rates scalable to 160 Gbps. A small fraction of the optical power emitted from each VCSEL is used to monitor the output power from each individual laser.
