An optoelectronic module may include an optical receiver optically coupled with an optical fiber. The optical receiver may be configured to receive time synchronization signals from the optical fiber. The time synchronization signals may be frequency modulated, wavelength modulated, or amplitude modulated and may be received along with received data signals. A time synchronization signal detection module may be communicatively coupled to the optical receiver. The time synchronization signal detection module may be configured to receive the time synchronization signals that are transmitted through the optical fiber and detect frequency modulations, wavelength modulations, or amplitude modulations to recover the time synchronization signals.

Bi-directional transceiver with time synchronization

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.

A system or a network may include an optoelectronic module that includes an optical transmitter optically coupled with an optical fiber, and a controller communicatively coupled to the optical transmitter. The controller may be configured to operate the optical transmitter to transmit data signals through the optical fiber. The optoelectronic module may be configured to transmit time synchronization signals through the optical fiber along with the data signals.
