发明名称 OPTICAL TRANSMISSION APPARATUS AND FAULT DETECTION METHOD
摘要 An optical transmission apparatus includes a non-reciprocal device including first to second ports, an optical signal input from the first port being provided to the second port, an optical signal input from the second port being provided to the first port, a dispersion compensator that is coupled to the first port of the non-reciprocal device and that conducts given processing to an optical signal input from the first port of the non-reciprocal device to provide the optical signal subjected to the given processing to the second port of the non-reciprocal device, a first monitor, a second monitor, and a fault determination device that compares a value monitored by the first monitor with a value monitored by the second monitor to determine a connection failure at the first and/or second ports of the non-reciprocal device and/or a connection state of the dispersion compensator.
