Abstract

A family of four port couplers is described which functions with 140/100pm and 230/200pm fibers. Tap ratios between 3 dB and 20 dB on the two output fibers are achieved with total throughput losses of less than 1.5 dB. A Bidirectional coupler offers a full duplex capability at a single wavelength for 140/100pm and 230/200pm fibers. Intrinsic channel isolation is in excess of 30 dB and coupled source-to-detector power throughput loss is less than 4 dB.
