  • Publication number: 20240097821
    Abstract: In an example of the disclosed techniques, a method comprising computing, by a computing system, a distribution of symbol errors in a forward error correction (FEC) frame transmitted in an optical signal. The method further includes, in response to determining that the distribution of symbol errors indicates a burst error that satisfies a threshold, adjusting, in an optical transceiver module, one or more of a pre-cursor setting, a post-cursor setting, or a signal amplitude for the optical signal.

  • Publication number: 20240056704
    Abstract: An example cascaded optical switch includes: a fast optical switch and a slow optical switch both having input ports and output ports. A switching time of the slow switch is longer than a switching time of the fast optical switch. The cascaded optical switch includes a first pre-cabled optical fiber connecting an output port of the slow optical switch to an input ports of the fast optical switch, and a second pre-cabled optical fiber connecting an output ports of the fast optical switch to an input ports of the slow optical switch. The fast optical switch or the slow optical switch is configured to receive configuration data to modify a switching configuration to configure a fiber cross-connect in the optical switch fabric that includes at least one of the first pre-cabled optical fiber or the second pre-cabled optical fiber.

  • Publication number: 20230224614
    Abstract: An example optical switch includes a plurality of input ports and a plurality of output ports, a cross-connect fabric having one or more inputs, one or more outputs, and a device to selectively cross-connect the inputs with the outputs. The optical switch includes an integrated fast optical switch comprising a first input, a first output, and a second output, wherein the first input is connected to a first one of the outputs of the cross-connect fabric, and wherein the integrated fast optical switch has a switching time that is less than a switching time of the cross-connect fabric to switch the first input between the first output on a path to a first output port of the plurality of output ports and the second output on a path to a second output port of the plurality of output ports.

  • Patent number: 11637637
    Abstract: Techniques are described for providing a hybrid compensation of chromatic dispersion in optical networks to reduce power consumption by coherent receivers. In some examples, a controller may receive a chromatic dispersion value of an optical signal from a coherent receiver integrated with a receiver optical network device. The controller may compare the chromatic dispersion value with a threshold. The controller may, in response to determining that the chromatic dispersion value satisfies the threshold, perform at least one of: configure a switch connected to a dispersion compensation module (DCM) with a state to provide access to the DCM to compensate the chromatic dispersion value of the optical signal, or adjust a phase response of a filter of a coherent transmitter to compensate the chromatic dispersion value of the optical signal.

  • Patent number: 10206017
    Abstract: In general, techniques are described for automatically configuring fiber cross-connects between customers of an interconnection facility. In some examples, a programmable network platform for an interconnection facility exposes an interface by which customers of the interconnection system provider may request fiber cross-connects to other customers of the interconnection system provider. The programmable network platform may, in response to a request for a fiber cross-connect, configure an optical switch fabric of the interconnection facility network infrastructure to create a fiber cross-connect between the demarcation points for the customers to be interconnected.
