Abstract
A fiberoptic network transmission system combines the output signals of several laser sources into a single optical fiber. The transmission system has integrated optical isolator couplers which each have at least two input optical fibers and an output optical fiber. Each input optical fiber is connected to a laser source and the output optical fiber is connected to an input terminal of a combiner which has its output terminal connected to the single optical fiber. The integrated optical isolator couplers block light from the single optical fiber from reaching any of the laser sources.
