OPTICAL LINKS

摘要

An optical link (10) is described for transmitting a microwave signal (30) in modulated optical form over an optical fibre (24). The optical link (10) has a transmitter (12) and a receiver (18). The transmitter (12) splits and converts the microwave signal (30) into two separate optical signals (34 and 36), each of which represent either the positive varying part of the microwave signal (30) or the negative varying part of the microwave signal (30). The receiver (18) combines the two separate optical signals (34 and 36) and converts them back into the microwave signal (30).
