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: Systems and methods are provided for achieving graceful bandwidth scaling (i.e. higher data transmission rates) for Coarse Wavelength Division Multiplexing (CWDM) and CWDM-4 technologies. Examples utilize a waveband architecture built around the CWDM wavelengths. This waveband architecture adds additional wavelength transmission channels (which may equate to faster data transmission rates) while maintaining backwards compatibility with existing CWDM/CWDM-4 technologies. Examples may include waveband devices (e.g. waveband light sources, waveband transmitters, waveband receivers, waveband transceivers, etc.) designed to operate with one or more CWDM wavebands while maintaining backwards compatibility with existing CWDM-4 technologies.
