Abstract: Pluggable optical transceiver modules are described herein that are specifically configured to preclude use of fiber jumpers inside of the module. The pluggable optical transceiver modules include an on-board application-specific integrated circuit (ASIC), optical transceiver, and an optical socket allowing a fiber to connect to the optical transceiver. Pluggable optical transceiver modules implement an opto-mechanical interface between an external fiber cable (attached to the pluggable optical transceiver module) and the optical transceiver in manner that does not require the fiber jumper, while ensuring tight alignment tolerances. In some embodiments, optical transceiver modules are designed to achieve a direct opt-mechanical coupling between the external fiber cable and on-board opto-electrical components (e.g., optical transceiver). For example, an adaptor is distinctly designed, directly connecting an external cable to the optical socket (eliminating the use of fiber jumper and faceplate connector in the module). In some embodiments, a rigid body opto-mechanical interface is used.

Abstract: Systems and methods are provided for flexible wavelength assignments in a communication network. An optical adapter is provided for the systems and methods. The optical adapter has a first interface connected to an optical switch via a first optical cable, a second interface connected to a plurality of server ports via a plurality of second optical cables, and a controller coupled to a switch controller of the optical switch. The controller is configured to perform: obtaining instructions from the switch controller; and assigning, based on the instructions, one or more wavelengths for a time slot to one of the server ports, wherein the controller performs the assigning without direct communication with the server ports.

Abstract: Waveguide shuffle blocks (WSBs) are provided that may incorporate waveguides routed in any pattern to effectuate many-to-many connectivity between optical cables/fibers or other WSBs connected thereto. Such WSBs may be configured in ways that allow the WSBs to be stacked and to achieve effective optical cable/fiber organization. Moreover, such WSBs may include readable tags that can provide information regarding a particular WSB configuration and/or what optical cables/fibers are connected so that network topology can be discovered and monitored. Some WSBs may be configured as wavelength shifting shuffles (WSSs) that allow a particular wavelength(s) of an optical signal(s) to be routed as desired and/or alter a first wavelength associated with a particular optical signal to a second wavelength. In other embodiments WSSs can be configured to allow for wavelength multiplexing/demultiplexing.
