摘要： This apparatus of bidirectional optical recirculation loop transmission enables bidirectional transmission system to be tested in the long transmission distance. Unidirectional optical recirculation loop is composed of two optical modulators and one 4-port optical coupler. Bidirectional optical recirculation loop is composed of four optical switches, one 4-port optical coupler and six optical circulators. Two optical circulators at the entrance (simultaneously exit) of the loop enable transmitted (received) signals to be added (dropped). Four optical circulators enable forward (reverse) signal to bypass the optical switch set for reverse (forward) signal in the inner optical loop. Forward (reverse) signal can be transmitted simultaneously with the reverse (forward) signal without interference. Two independent optical recirculation loops exist on the same fiber link in each direction.

The system for monitoring the optical transmission line includes: an OTDR (optical time-domain reflectometer) transmitting a monitoring light to an optical transmission line, measuring a reflected light or backscattered light to monitor the optical transmission line; an optical amplification unit amplifying the monitoring light transmitted on the optical transmission line by using a gain clamped optical amplifier; and a filter unit removing a component having a wavelength outside a wavelength band of the monitoring light from a backward ASE (amplified spontaneous emission) generated by the optical amplification unit. Accordingly, it is possible to extend an optical transmission line monitoring distance of the OTDR. As a result, it is possible to prevent deterioration of the performance of the OTDR because of the backward ASE.
