Abstract

An apparatus, system and method for facilitating higher bandwidth communication in a data center using existing multi-mode fibers. A first transceiver within a first device transmits Ethernet traffic to a second device over first and second optical fibers and receives return optical signals over the same first and second optical devices. By varying the wavelengths between the transmitted and received optical signals, the same optical fibers can be used to both transmit and receive optical signals. A second transceiver within the same housing as the first transceiver performs the same function. In this fashion, one device can be coupled to four bidirectional optical fibers, each transmitting and receiving optical signals at 20 Gbps.
