Pluggable optical transceiver modules are described herein that are specifically configured to preclude use of fiber jumpers inside of the module. Pluggable optical transceiver modules implement a rigid-plane jumper that provides an opto-mechanical interface between an external fiber cable (attached to the pluggable optical transceiver module) and the optical transceiver in a manner that does not require the fiber jumper, while ensuring reduced optical loss. In some embodiments one or more rigid waveguide plates act as an opto-mechanical coupling between the external fiber cable and on-board opto-electrical components (e.g., optical transceiver). For example, the rigid waveguide plates are coupled to a faceplate connector, and a CWDM block that is in turn optically coupled to the optical socket. In some embodiments, the CWDM block is directly attached to the rigid waveguide plates. In some embodiments, the CWDM block is indirectly attached to the rigid waveguide plates using a half periscope.

The plurality of the optical fibers is separated from the top surface of the PCB by a first minimum distance and from the top surface of the platform by a second minimum distance less than the first minimum distance.
