A new type of reflectometer has been described which provides excellent discrimination of reflections and does so with a minimal amount of low-cost, small hardware. The computations required can easily be handled by a 16-bit microcontroller working i

Optical Time Domain Reflectometry (OTDR) is a well-known means of testing a fiber optic cable assembly in optical networks. The OTDR launches a very narrow pulse into the fiber and then records the response of the cable/connector assembly to this pul

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 ind

Modern military avionics gigabit/second fiber optic links can be made relatively low-cost as the result of COTS-based VCSEL transceivers. However, such systems quite often consist of large numbers of components, due to multiple bulkhead disconnects a
