Implementations described and claimed herein provide systems and methods for a configurable optical peering fabric to dynamically create a connection between participant sites without any physical site limitations or necessity of specialized client and network provider equipment being located within such a facility. Client sites to a network may connect to a configurable switching element to be interconnected to other client sites in response to a request to connect the first client site with a second site, also connected to network, via the switching element. A request may trigger verification of the requested and, upon validation, transmission of an instruction to the switching element to enable the cross connect within the switching element. The first site and the second site may thus be interconnected via the switching element in response to the request, without the need to co-locate equipment or to manually install a jumper between client equipment.

A system comprising a hub transceiver and edge transceivers is described. The hub transceiver is coupled to a first network node via an optical communications network. Each of the edge transceivers is coupled to a respective second network node, and to the hub transceiver. The hub transceiver is operable to form one or more logical partition of optical subcarriers in an optical signal based on connection types. Each logical partition has a first partition boundary, a second partition boundary and a plurality of subcarriers logically between the first partition boundary and the second partition boundary. Each partition boundary is assigned a particular connection type. The hub transceiver assigns a subset of available optical subcarriers of the plurality of subcarriers where each assignment includes a number of optical subcarriers based on the connection type in the service request, and a subcarrier location within the one or more logical partition.

A system for optically aligning a photonics die to a fiber array, the fiber array comprising a first and a second fiber channels, the system comprising: the photonics die having: a first and a second optical channels; a first and a second wavelength division multiplexing (WDM) couplers each comprising a bar port, a cross port, and a common port, the first and the second WDM couplers being optically connected to the first and the second optical channels, respectively, via the bar ports and the common ports; and a waveguide crossing optically connecting the cross ports of the first and the second WDM couplers; the system being adapted to couple an optical signal received from the first fiber channel into the cross port of the first WDM coupler and into the waveguide crossing, the optical signal being propagated from the waveguide crossing into the cross port of the second WDM coupler.

The present disclosure describes a network including two levels of switching: a first level including wavelength selective switching via a first type of switching module, and a second level including fiber level switching via a second type of switching module. The two levels of switching allow for maintaining wavelength selective switching between transmission directions while introducing fiber selective switching between network degrees of the same transmission direction. The first type of switching module is configured to transmit and receive optical signals having a first set of wavelengths at a first network degree at a first direction in a node of a network. The second type of switching module is configured to transmit and receive the optical signals from the first type of switching module and route the optical signals at the first network degree to a second network degree in a second direction.

In an example method, an edge transceiver receives a first message from a hub transceiver over a first communications channel of an optical communications network, including an indication of available network resources on the optical communications network. The edge transceiver transmits, over a second communications channel of the optical communications network, a second message to the hub transceiver, including an indication of a subset of the available network resources selected by the edge transceiver. The edge transceiver receives, from the hub transceiver, a third message acknowledging receipt of a selection by the edge transceiver and a fourth message confirming an assignment of the selected subset of the available network resources to the edge transceiver. The edge transceiver transmits, using the selected subset of the available network resources, data via the hub transceiver.

An example system includes a hub transceiver and a plurality of edge transceivers. Each of the edge transceivers has one of several types of configurations for communicating with an optical communications network. Each type of configuration is associated with a different responsive optical subcarrier assignment protocol. The hub transceiver is operable to determine a plurality of optical subcarriers available for assignment by the hub transceiver to the plurality of the edge transceivers for use in communicating over the optical communications network, and assign, to each of the edge transceivers, a respective subset of the optical subcarriers. Assignment includes, determining that each of the edge transceivers has a particular type of configuration, and assigning a respective subset of the optical subcarriers to the edge transceiver according to the optical subcarrier assignment protocol associated with the that type of configuration.
