A diagnostic system includes a detection circuit comprising a first impedance, a second impedance, a first input pin, a second input pin, a first output pin and a second output pin. The detection circuit is configured to receive an input signal via the first and the second input pins. The first impedance is configured to electrically couple the first input pin and the first output pin, and the second impedance is configured to electrically couple the first input pin with the second input pin and second output pin. The diagnostic system also includes a communication channel. The diagnostic system further includes an input circuit comprising a third input pin, a fourth input pin and a third output pin. The input circuit is configured to provide, via the third output pin, a voltage signal.

Diagnostic system

A method of tuning optoelectronic transceivers in an optical network may include powering on a first optoelectronic transceiver, setting a channel wavelength of the first optoelectronic transceiver, transmitting a first request command from the first optoelectronic transceiver through the optical network to a second optoelectronic transceiver, and non-iteratively changing a channel wavelength of the first optoelectronic transceiver until a second request command is received from the second optoelectronic transceiver. The second request command may indicate to the first optoelectronic transceiver that the channel wavelength set by the first optoelectronic transceiver is able to travel through the optical network between the first optoelectronic transceiver and the second optoelectronic transceiver.

Tuning optoelectronic transceivers in optical network

A method of tuning optoelectronic transceivers in an optical network may include powering on an optoelectronic transceiver, setting the channel wavelength of the optoelectronic transceiver, transmitting a request command from the optoelectronic transceiver through the optical network to another optoelectronic transceiver; and waiting to receive a second request command from the another optoelectronic transceiver.
