Claim 6:
7. An apparatus, comprising:
a coupler;
a first switch operatively coupled to the coupler;
a second switch operatively coupled to the coupler;
a first port operatively coupled to the first switch, the first switch located between the coupler and the first port;
a second port operatively coupled to the second switch, the second switch located between the coupler and the second port; and
a processor, operatively coupled to at least one of the coupler, the first switch, the second switch, the first port, or the second port, the processor configured to:
detect, in a bidirectional port operation mode and via the second port, an optical signal that includes a control signal,
detect that a signal characteristic of the control signal has one of fallen below a predetermined threshold or exceeded the predetermined threshold, and
implement active switching via the coupler, the first switch, and the second switch 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.
