Abstract

We present here a high performance OTDR based on Pseudo Random Binary Sequences (PRBS) for solving resolution and dead zone problem associated with fiber and fiber connector inspections. The presented system has the capability of spatial resolution and dynamic range that are compatible with the application and will allow efficient measurement of defects in fiber connectors, independent of the measurement of the airgap reflection. The dynamic range of the system used is 41dB and using components of higher frequency (10 GHz) it could be modified for resolution of 2 cm with atleast 76 dB of dynamic range in a 40ft cable. This capability will allow for independent measurement of airgaps inside connectors, and defect at the backend of the same connectors in aircrafts, and increase the readiness of its fleet at lower cost of ownership.
