An optical connector assembly (OCA) includes a connector housing to maintain alignment between optical components housed within the OCA and photoelectric converters on an optoelectronic substrate (OES) assembly. The optical components include a ferrule and an optical cable. The ferrule is optically coupled to the optical cable. The OCA includes a ferrule holder to hold the ferrule within the OCA, and a spring located between the connector housing and the ferrule holder. The spring is to apply a separating force between the ferrule holder and the connector housing. The OCA includes a gasket coupled to the connector housing. The coupling of the connector housing to a socket compresses the gasket to provide a seal between the connector housing and the socket.

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.

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.
