Management solution to monitor the reflected fiber optic signal from the optic cable line to transfer the multichannel CWDM

摘要

the invention using the low-density optical wavelength to wavelength division multiplexing (CWDM: Coarse Wavelength Division Multiplexing) transmission systems in When the transmission and reception using the same wavelength in the optical signal incident on the optical system of the optical track is reflected due to a bad connection problems of the PC-type connector used in the cutting of the optical cable or optical cable (Physical Contact type Connector) call occurs. reflection light signal is traveling in the reverse direction is input to the re-transmission system is the management system normally does not occur if it is determined that the received optical signal is detected an error on the transmission, or does not transmit the data through an optical signal The. And to monitor and enters the low-density wavelength division multiplexing (CWDM) transmission n of 1 is added to add the channel optical signal caused by the reflection in addition to the channel for the transmission channel used in the system in order to manage these problems early detection system will detect the reflected light signal from the module on how to detect a malfunction at an early stage by monitoring the reflected light of the reflection system is a multi-channel low-density wavelength division multiplexing (CWDM) transmission system to normal operation.
