A device may receive optical network information associated with a plurality of super-channels. Each super-channel, of the plurality of super-channels, may include a plurality of optical channels transported as a single optical channel. The device may assign the plurality of super-channels to a plurality of sets of super-channels. The device may receive a request for a subset of the optical network information associated with a set of super-channels of the plurality of sets of super-channels. The device may provide, based on the request, information that identifies the subset of the optical network information associated with the set of super-channels via a user interface.

This disclosure relates to optical line system equipment, which enables wavelength addition for long haul transmission. The system is configured to prevent contention of wavelengths added into a multiplexer. For example, an optical wavelength combiner, such as a multiplexer, may include components that are configured to detect potential collisions between existing wavelengths and a newly added wavelength, and block the addition of the conflicting wavelength while alerting the operator.

Systems and methods are disclosed including a method comprising: receiving, with a controller having a computer processor, a preservation status input from a user indicative of whether or not to preserve a virtual local area network (VLAN) tag in a header of a data packet transmitted within an Ethernet local area network (E-LAN), the VLAN tag identifying at least one of customer information and service provider information for the data packet in the E-LAN, wherein the E-LAN comprises network devices having physical ports and is configured to allow multiple customers use of an individual physical port; determining a scalable network-wide service configuration model having multiple predetermined rules for automatically configuring the physical ports of the network devices for the E-LAN based on the preservation status input from the user; and configuring automatically, with the controller, the physical ports of the network devices using the predetermined rules of the configuration model.


Various apparatus and methods may use iterative de-mapping/decoding to on received symbol estimates corresponding to interleaved coded modulation (ICM) using low-density parity check convolutional coding (LPDC-CC). The iterative de-mapping/decoding, may take the form of a multi-stage feed-forward arrangement that may include multiple identically designed stages, and the stages may use parallelism to increase speed and efficiency.


A device may include a first substrate. The device may include an optical source. The optical source may generate light when a voltage or current is applied to the optical source. The optical source may be being provided on a first region of the first substrate. The device may include a second substrate. A second region of the second substrate may form a cavity with the first region of the first substrate. The optical source may extend into the cavity. The device may include an optical interconnect. The optical interconnect may be provided on or in the second substrate and outside the cavity. The optical interconnect may be configured to receive the light from the optical source.
