In one embodiment, a router includes a plurality of line cards each
operable to receive at least one packet comprising an identifier
associated with a destination element external to the router. Each line
card includes a look-up table operable to facilitate routing the received
packet toward the destination element based at least in part on the
identifier. The router further includes a plurality of optical
transmitters each associated with one of the line cards and operable to
generate at a specified wavelength an optical router signal comprising at
least a portion of the packet received by the line card associated with
that optical transmitter. The router also includes a star switching
fabric operable to receive a plurality of optical router signals from the
plurality of optical transmitters and to communicate to each of a
plurality of tunable filters a substantially similar set of at least some
of the plurality of optical router signals. Each of the plurality of
tunable filters is operable to selectively tune to a wavelength of one of
the plurality of optical router signals to facilitate communication of
the packet associated with that optical router signal toward the
destination element.
