Gigabit Fiber Optic Transceiver Technology Evolution for Avionics

In this paper we discuss the advantages (and disadvantages) of commercial sector gigabit fiber optic transceiver circuit evolution for avionics applications. We provide insight into some of the shortfalls that still exist with respect to avionics industry needs concerning fiber optic link health diagnostics, fault detection, and fault isolation. We close this paper with a first glance at the demonstration of a gigabit transceiver with in service OTDR capability for isolating faults in avionics fiber optic network cable plants
