Abstract: A compact optical transceiver is provided in which a substrate provides for an alignment surface for optical fibers and a lens assembly provides the necessary optical paths for coupling to photodiode and photodetector structures. Appropriate electrical connections on the substrate enable the substrate to be directly connected to a printed circuit board, grid array socket, and the like.

Abstract: A system is provided for implementing PCI Express protocol signals over an optical link. A transmission circuit is used to provide an electrical-to-optical conversion, a receiving circuit provides an optical-to-electrical conversion, and a sideband circuit is used to provide and receive control information.

Abstract: A universal routing identifier (URID) is provided to extend the function space in PCI-Express fabrics. Methods and systems based on the URID are provided for configuring URID capable devices and upgrading PCI-Express bridges and switches having lookup tables with access control functionality. The lookup table entry contains URIDs of destination ports, backup ports, acceptance ports, and permitted ports for downstream and upstream filtering, routing and arbitrating of transaction packets. URID capable devices can be incrementally added to current PCI-Express bridges and switches. A configuration mechanism is added to the current PCI/PCI-Express enumeration software. The URID capabilities can be disabled to maintain system compatibility. A URID capable PCI-Express system is able to address ten of thousands single-function devices. A URID capability segment field is provided in the current PCI-Express configuration space.

Abstract: A connector module is provided that includes a longitudinal body adapted for installation in a computer equipment rack capable of housing a plurality of server units positioned in a stack configuration. The longitudinal body has a plurality of data connectors mounted along an outer surface. Each data connector is located at a different location along the outer surface of the longitudinal body and is adapted to receive a signal source introduced from a front side of the outer surface. The connector module includes a collection of signal paths coupled to the plurality of data connectors. Signal paths are positioned toward a backside of the outer surface. The longitudinal body is adapted for installation in a transverse orientation relative to the plurality of server units in the stack configuration such that each data connector is positioned in proximity to a connector mounted on a corresponding one of the server units.

Abstract: A data transmission assembly includes a first connection terminal coupled to a processing unit and a second connection terminal coupled to a random access memory (RAM) resource. The data transmission assembly also includes a first electrical/optical (EO) signal converter and a second EO signal converter. The first EO signal converter is coupled to the first connection terminal and the second EO signal converter is coupled to the second connection terminal. The data transmission assembly also includes an optical signal propagation medium with a first end and a second end. The first end is attached to the first EO signal converter, and the second end is attached to the second EO signal converter. The signal propagation medium carries signals between the first connection terminal and the second connection terminal to support memory accesses performed by the processing unit to access data at memory locations within the RAM resource.
