Abstract

An optical transceiver system is provided that comprises multiple parallel transceiver modules that are mounted on a card. The transceiver card is small in terms of spatial dimensions, has very good heat dissipation characteristics, and is capable of simultaneously transmitting and receiving data at a rate equal to or greater than approximately one Tb per second (1 Tb/s). A plurality of the transceiver systems may be interconnected to achieve a communications hub system having even higher bandwidths. In addition, the transceiver system may be configured such that each card has a routing controller mounted thereon for performing router functions. The router functions include, for example: causing signals received by one transceiver module on the card to be routed to and transmitted by another of the transceiver modules; causing signals received by one transceiver module on the card to be retransmitted by the same transceiver module over one of it's optical transmit channels; and causing signals received by one transceiver module on the card to be routed to and transmitted by a transceiver module on a different card.
