Abstract
An optical transceiver assembly comprises a plurality of optical signal sources for providing downstream signals and a plurality of photodetectors for detecting upstream signals. An optical module is disposed between the optical signal sources and the photodetectors, where the optical module includes a surface transmissive to either one of the downstream and upstream signals, and substantially reflective to the other of the downstream and upstream signals, diffractive regions for deflecting the downstream signals into the optical fibers and the upstream signals into the optical module. The optical module also includes diffractive regions for deflecting the downstream signals from the optical signal sources into the optical module and the upstream signals into the photodetectors. The optical module additionally includes an array of lenses for imaging the downstream signals into the optical module and into the optical fibers, and for imaging the upstream signals into the optical module and into the photodetectors.
