Abstract

A system and method for embedding or multiplexing an in-service optical time domain reflectometry (ISOTDR) or in-service insertion loss (ISIL) session. A preferred embodiment embeds the sessions using the same wavelength as the data traffic for point-to-point or point-to-multipoint optical fiber networks without interrupting or affecting the primary data transmission process.

Claims

1. An apparatus for in-service testing of an optical network comprising:

an optical transmitter used for data communications; and

a control module configured to multiplex a test light transmission onto a data wavelength over a path from the optical transmitter to a first terminal in the network.

wherein the control module is further configured to multiplex the test light transmission within a desired period of the network communication protocol used by the network.
