Network Experiment Using an 8,000-GHz-Tuning-Range Optical Filter.
01 January 1988
A tunable optical filter with 180 MHz resolution and continuous tuning range of 8,000 GHz was used in a lightwave network experiment. Three 50 Mb/s channels with minimum channel spacing of 1.6 GHz and maximum channel spacing of 4,000 GHz were individually received error-free in the presence of interfering optical power corresponding to 6,000 channels.
