Abstract: A planar lightwave circuit (PLC) assembly is used for a transceiver module that includes a circuit board having photodetectors mounted at a spacing from one another. A transmitter mounted on the circuit board is configured to transmit optical signals for a network. The PLC assembly includes at least one PLC chip and at least one fiber array. The PCL chip mounts on the transmitter and is configured to receive optical signals for the network. The fiber array has optical fibers connecting between the PLC chip and the photodetectors. The array's first end connected to the PLC chip has a first pitch between the optical fibers, while the array's second end has at least one connector connected adjacent the photodetectors and having a second fiber pitch, which is greater than the first pitch and is configured to the spacing of the photodetectors.

Abstract: An Inifiniband (IB) network that incorporates a Fibre Channel (FC) network is disclosed. The IB and FC networks are coupled by a gateway that maps the FC network to a virtual IB network. In generating the virtual IB network, the gateway may provide a virtual IB target for each node port in the FC network, and may further provide a minimum number of virtual IB switches necessary to support the virtual IB targets. The gateway assigns a globally unique identifier (GUID) to each of the virtual IB targets, and may further associate local identifiers (LID) with the virtual IB targets. The gateway preferably emulates subnet management agents (SMA) and general service agents (GSA) of the virtual IB targets when management IB packets are received, and the gateway preferably converts non-management IB packets directed to the virtual IB targets into FC frames directed to the corresponding target FC devices.

Abstract: An isolation switch blade Fibre Channel switch presents F_ports to form a first Fibre Channel fabric and N_ports to a second Fibre Channel fabric to appear as node devices. The isolation switch blade may be used to connect a plurality of blade servers to a Fibre Channel fabric. Fabric events engendered by the insertion or removal of hot-pluggable devices are handled by the isolation switch blade and “event storms” on the Fibre Channel fabric are avoided. The isolation switch blade presents the blade servers to the FC fabric as a virtualized N_port.
