Summary: 
A bit-error-free optical signal switching method from one to another fiber has been proposed for high-bit-rate optical transmission lines. The intensity modulated signal powers of 1.8 Gbit/s, which had been divided by an acousto-optic deflector and propagated through the 2 fibers, were recombined without bit-errors. Optical signals were switched successfully between 25 km long fibers without degradation of bit-error-rate performance.
