ABSTRACT:
A system and method for performing an in-service optical time domain reflectometry (OTDR) and/or insertion loss (IL) measurement(s) using the same wavelength as the data traffic for point-to-point or point-to-multipoint optical fiber networks. The OTDR or IL sessions are multiplexed in accordance with the network protocol in use to avoid any distortion of data transmissions.
