Abstract

Due to trends toward data bus multiplexing, we have developed low-insertion loss (about 1 dB) optical access couplers for interconnecting, by fiber optic waveguide cables, several spatially distributed terminals. The fabrication technique and modal properties of the optimized couplers are discussed. Using two 3 dB couplers we have demonstrated full duplex operation on a single 330 meter fiber. The signal levels at the detector associated with both the desired signal from the far end and the interference signal from the local source have been analyzed and measured. System design and techniques to decrease the signal-to-interference ratio are discussed.
