Abstract
Official abstract text for this publication.
Disclosed is an apparatus for monitoring failure positions on fibers in a WDM-PON system and a WDM-PON system having the apparatus.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus comprising: a light source to generate a first monitoring light to propagate over a fiber, the fiber configured to transmit data in at least one of data transmission wavelength bands; a first broadband light source (“BLS”) for outputting an incoherent light in a monitoring wavelength band that is different from the at least one of the data transmission wavelength bands, the incoherent light to be injected into the light source to generat…
