Abstract
An optical communications module is provided that has WDM capabilities for increased bandwidth and that is suitable for use with single mode optical fiber or multimode optical fiber. The module can be configured to have both WDM and BiDi functionality to further increase bandwidth and can have a single- or multi-channel configuration. The module has an integrally-formed body having an optical port and portions of an optical coupling system that are integrally formed in the body. The optical port is adapted to mate with an end of an optical fiber cable that holds one or more ends of one or more optical fibers, depending on whether the module is a single-channel or multi-channel module. The optical coupling system couples light between an end or ends of one or more optical fibers and one or more optoelectronic devices in a way that reduces back reflection and mode partition noise.
