- نبذة مختصرة :
An interconnect module (“ICAS module”) includes n optical data ports each comprising n optical interfaces, and an interconnecting network implementing a full mesh topology for interconnecting the optical interfaces of each port each to a respective one of the optical interfaces of each of the other ports. In one embodiment, each optical interface exchanges data signals over a communication medium with optical transceiver. The interconnecting module may implement the full mesh topology using optical fibers. The interconnecting module may be used to replace fabric switches as well as a building block for a spine switch.
