Abstract:
A small form factor pluggable (SFP) device includes a controller for receiving a first input signal. An optical loopback circuit is coupled to the controller for feeding back a loopback signal to the controller. The loopback signal is generated from the first input signal. An indicator is coupled to the controller for indicating a operational status of the device.
