Abstract: A sourceless co-packaged optical-electrical chip can include a plurality of different optical transceivers, each of which can transmit to an external destination or internal components. Each of the transceivers can be configured for a different modulation format, such as different pulse amplitude, phase shift key, and quadrature amplitude modulation formats. Different light sources provide light for processing by the transceivers, where the light source and transceivers can be configured for different applications (e.g., different distances) and data rates. An optical coupler can combine the light for the different transceivers for input into the sourceless co-packaged optical-electrical chip via a polarization maintaining media (e.g., polarization maintaining few mode fiber and polarization maintaining single mode fiber), where another coupler operates in splitting mode to separate the different channels of light for the different transceivers according to different co-packaged configurations.

Abstract: In some examples, a network device comprises one or more processors operably coupled to a memory, and a routing unit configured for execution by the one or more processors to route data traffic on a layer 3 network overlaying an optical transport system; receive optical supervisory channel data for an optical supervisory channel of the optical transport system; determine the optical supervisory channel data indicates an event affecting transmission or detection of a signal transported by a wavelength, the wavelength traversing an optical fiber of the optical transport system and underlying a link of the layer 3 network; and reconfigure, in response to determining the optical supervisory channel data indicates the event, a configuration of the network device to modify routing operations of the network device with respect to the data traffic on the layer 3 network.
