Bi-Directional Coupler for Full Duplex Transmission on a Single Fiber

摘要

The primary objective of this contract is the development of a bi-directional coupler for single optical fiber transmission systems and the implementation of two such couplers in a full duplex link with simulated length of up to 8 km, 20 Mb/s data rate, and 10 to the -8th power BER. The primary approach adapted for this task is the fiber dichroic coupler. Other approaches were also investigated. When used in a duplex optical data link, this three port device constitutes a wavelength selective bi-directional coupler. (Author)
