A transponder and system for monitoring the status of equipment, such as an optical node, on a network are described. The transponder has an external fiber optic input connection element, an external fiber optic output connection element, an internal receiver connected to the input connection element for converting incoming optical signals to electrical RF signals for use internally within the transponder, and an internal transmitter connected to the output connection element for converting outgoing electrical RF signals to optical signals to be transmitted from the transponder. The transponder also includes status monitoring circuitry interfacing with equipment being monitored and a cable modem communicating with the status monitoring circuitry for receiving information therefrom and for generating an outgoing signal. A method of monitoring the status of an optical node on a network is also disclosed. |
