Abstract

A wavelength division multiplexing / demultiplexing optical transceiver module is provided that is suitable for use in single mode optical fiber (SMF) and multimode optical fiber (MMF) optical communications links. When used in an MMF optical communications link, the optical transceiver module allows the length and bandwidth of the link to be increased significantly. The optical transceiver module can be used advantageously in an MMF link that includes existing MMF infrastructure to increase the bandwidth of the MMF link while avoiding the costs associated with pulling new higher-bandwidth fiber.

Description

technical field [0001] The present invention relates to fiber optic networks, and more particularly to optical transceiver modules, optical links, and methods of increasing the bandwidth of multimode fiber optic links. Background technique [0002] In optical communication networks, optical transceiver modules are used to transmit and receive optical signals via optical fibers. An optical transceiver module includes a transmitter side and a receiver side. On the transmitter side, a laser light source produces modulated laser light and an optical coupling system receives the modulated laser light and optically couples or images the light onto the end of an optical fiber. The laser light source is typically a laser diode or light emitting diode (LED) that produces light of a specific wavelength or range of wavelengths. The driver circuit on the emitter side outputs an electrical drive signal that modulates the laser diode or LED. The optical coupling system typically includ...
