Claim 12:
13. A method, including:
detecting, in a bidirectional port operation mode and via a second port operatively coupled to a second switch located between a coupler and the second port, a third optical signal that includes a control signal, and not receiving a first optical signal and a second optical signal during the detecting;
in response to detecting that the signal characteristic of the control signal has one of fallen below the predetermined threshold or exceeded the predetermined threshold, implementing active switching via the coupler, a first switch operatively coupled to the coupler and a first port, and the second switch;
switching between the bidirectional port operation mode and a unidirectional port operation mode;
sending, in the unidirectional port operation mode and via the first port, the first optical signal and not sending and not receiving the second optical signal while sending the first optical signal;
receiving, in the unidirectional port operation mode and via the second port, the second optical signal;
sending, in the bidirectional port operation mode and via the first port, the first optical signal; and
receiving, in the bidirectional port operation mode and via the first port, the second optical signal.
