ABSTRACT:
A system for identifying transmission rates of an optical signal transmitted in an optical communication network includes a signal converter for converting a sample of the optical signal to an electrical signal. A frequency analyzer analyzes the electrical signal to determine energy levels of the signal at predetermined frequencies. The detected energy levels are stored in a first memory device. A second memory device stores known energy levels at predetermined frequencies for a plurality of known optical transmission standards. A comparator receives the detected energy levels stored in the first memory device and compares this information to the known transmission standards stored in the second memory device in order to identify the data transmission standard of the optical signal.
