Claim Text:
1. A bidirectional pentaplex system connected to a machine room, the machine room providing a first optical signal, a second optical signal and a monitoring signal and transmitting to the bidirectional pentaplex system, the bidirectional pentaplex system comprising: a filter, for receiving the first optical signal, the second optical signal and the monitoring signal, wherein the filter is penetrated by the monitoring signal, and reflects the first optical signal and the second optical signal; a transceiver, for receiving the monitoring signal from the filter; a grating, for receiving the first optical signal and the second optical signal reflected by the filter, splitting the first optical signal and the second optical signal; a first reflecting unit, for receiving the first optical signal spilt by the grating and then reflecting the first optical signal; a second reflecting unit, for receiving the second optical signal split by the grating and then reflecting the second optical signal; a first receiving unit, for receiving the first optical signal reflected by the first reflecting unit; a second receiving unit, for receiving the second optical signal reflected by the second reflecting unit; a control circuit, electrically connected to the first receiving unit, the second receiving and the transceiver, wherein the transceiver receives the monitoring unit, the control circuit controls the transceiver emitting a third feedback signal, and the feedback signal penetrates the filter and transmits back to the machine room; a first emitting unit, electrically connected to the control unit, wherein the control circuit controls the first emitting unit emitting a first feedback signal; a second emitting unit, electrically connected to the control unit, wherein the control circuit controls the second emitting unit emitting a second feedback signal; a third reflecting unit, for receiving the first feedback signal emitted by the first emitting unit, and reflecting the first feedback signal back to the machine room; and a fourth reflecting unit, for receiving the second feedback signal emitted by the second emitting unit, and reflecting the second feedback signal back to the machine room.
