OPTICAL CHANNEL SENSITIVE BROADBAND INJECTION LIGHT SOURCE CAPABLE OF IMPROVING THE EFFICIENCY OF THE RESOURCES AND AN OPTICAL NETWORK SYSTEM FOR THE SAME

摘要

PURPOSE: An optical channel sensitive broadband injection light source and an optical network system for the same are provided to check the connection status of optical channels and offer a large-intensity injection light source only for optical channels for which the optical connection is secured.;CONSTITUTION: An optical line terminal includes a broadband light source (BLS) (20) and an optical splitter (30). The BLS provides an injection light source for the transmission of optical signals to an optical transmitter. The optical splitter re-injects the optical signals, which are wavelength-locked and sent by the optical transmitter, to the BLS. A broadband light source checks the channel connection status of the re-injected optical signals by the optical splitter. The broadband light source adjusts the signal strength of the optical signals. The broadband light source outputs the adjusted optical signals to the injection light source for the connected channels.;COPYRIGHT KIPO 2013;[Reference numerals] (20) Broadband light source (BLS); (30) Optical splitter; (40) Broadband 1XN wavelength router
