    Abstract: 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.

    Abstract: 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.

    Abstract: In an example, a communication module includes an optical transmitter, an optical receiver, and a periodical filter. The optical transmitter is configured to emit an outbound optical signal. The optical receiver is configured to receive an inbound optical signal. A first frequency of the outbound optical signal is offset from a second frequency of the inbound optical signal by an amount less than a channel spacing of a multiplexer/demultiplexer implemented in an optical communication system that includes the communication module. The periodical filter is positioned in optical paths of both the outbound optical signal and the inbound optical signal and has a transmission spectrum with periodic transmission peaks and troughs. The first frequency of the outbound optical signal may be aligned to one of the transmission peaks and the second frequency of the inbound optical signal may be aligned to one of the transmission troughs, or vice versa.

    Abstract: In some aspects, an example method may include receiving, at a receiver of a first optoelectronic module, a loss of signal indicator from a second optoelectronic module that is remote from the first optoelectronic module. The method may include iteratively cycling through transmission of optical signals on a plurality of wavelength channels to the second optoelectronic module until the loss of signal indicator terminates in response to receiving the loss of signal indicator. The method may include continuing to transmit the optical signal on a particular one of the plurality of wavelength channels in response to the loss of signal indicator terminating while transmitting an optical signal on the particular one of the plurality of wavelength channels.
