Abstract
There is provided a system and a method for extracting data traffic from an optical communication fiber by extracting a portion of the optical signal(s) propagating in the optical communication fiber, carrying the extracted signal over an optical fiber, amplifying the extracted optical signal and filtering the amplified signal to select one channel carrying data traffic. The optically-carried data traffic may then be input to an optical communication transceiver for converting the optically-carried data traffic into electrical data traffic, which carried data can be analyzed for data traffic monitoring applications.
