Leading Communications Companies Release the QSFP Specification: The Industry's Highest Density Pluggable Optical Module.EATONTOWN, N.J. -- Highest Density Quad Small Form-factor Pluggable (QSFP) optical module complements industry standard SFP SFP Small Form-factor Pluggable (optical transceiver module) SFP Société Française de Physique (French Physics Society; Paris) Sfp Svenska Folkpartiet (Finnish: Swedish People~s Party) optical module for Telecommunications and Data Communications Equipment See DCE. Data Communications Equipment - Data Communication Equipment Several industry leading communications companies Communications Company is a communications unit of the United States Marine Corps. They are part of Combat Logistics Regiment 37 , 3rd Marine Logistics Group (3MLG) and III Marine Expeditionary Force (III MEF). The unit is based out of the Marine Corps Base Camp Smedley D. today announced the release of a Quad (4-channel) Small Form-factor Pluggable (QSFP) optical module specification draft for public review. The group has developed a common specification for multi-sourcing, application-agnostic, highest density, pluggable optical modules. These modules optimize real-estate, power, and port density requirements in networking equipment while keeping synergy and compatibility to installed optical module interconnect infrastructure. Current members of the QSFP MSA (Metropolitan Service Area) An urban area with at least 50,000 people plus surrounding counties. There are 306 MSAs and 428 RSAs (rural service areas) in the U.S. MSAs and RSAs are used to allocate cellular licenses. group include the following companies:

The QSFP Specification defines a highly integrated 4-channel optical transceiver (TRANSmitter reCEIVER) An electronic device or circuit that transmits and receives analog or digital signals. It comes in many forms; for example, a transponder on a satellite, a network adapter in the computer or the circuits in a cellphone. to replace four standard SFP transceiver The small form-factor pluggable (SFP) is a compact optical transceiver used in optical communications for both telecommunication and data communications applications. modules providing increased port density and total system cost saving. The device will support Ethernet, Fibre Channel, InfiniBand and SONET/SDH standards with different data rate options. The QSFP MSA document specifies a transceiver module mechanical form factor with latching latch n. 1. A fastening, as for a door or gate, typically consisting of a bar that fits into a notch or slot and is lifted from either side by a lever or string. 2. mechanism, host board electrical edge connector The protruding part of an expansion board that is inserted into an expansion slot. It contains a series of printed lines that go to and come from the circuits on the board. The number of lines (pins) and the width and depth of the lines are different on the various interfaces (ISA, EISA, and cage. The hot-pluggable module integrates four transmit and four receive channels with a standard MPO MPO myeloperoxidase. MPO Myeloperoxidase, see there parallel optical connector. The QSFP device features digital diagnostic capability to monitor the link performance. The module is designed to enable extremely high-density applications with stacked and ganged configurations. This highly integrated transceiver module will enable network equipment manufacturers to increase port density and system data throughput and consequently reduce costs per Gigabit per second. With a port density of three times higher than traditional SFP transceivers, the QSFP can be used to replace four standard SFP modules in space that is only 30 percent larger than a single SFP; The QSFP requires approximately the same front-panel space of an XFP XFP 10 Gigabit Small Form Factor Pluggable Module XFP Extra-Fine-Pitch XFP Ten Gigabit Small Form Factor Pluggable module. Due to the increased capabilities, over 3X (3.11) times more transceivers can be placed in a given area on a switch or product. The QSFP's unique design repackages the existing SFP transceiver in a way which utilizes a 12-fiber ribbon instead of individual fibers. Additionally the QSFP design supports Ethernet, Fibre Channel, Infiniband and SDH/SONET with data rates up to 5Gb/s per channel. The QSFP platform demonstrates potential for aggregated higher volumes and improved economics realized from several protocols/applications using the same transceiver. The QSFP MSA is the world's first Z-pluggable parallel optical transceiver and has multi-vendor support offering potential customers a variety of purchasing options. The QSFP group brings together leading networking, system, optical module, semiconductor and connector companies from both the telecommunications and data communications data communications, application of telecommunications technology to the problem of transmitting data, especially to, from, or between computers. In popular usage, it is said that data communications make it possible for one computer to "talk" with another. markets. In addition, the inherent 4+4 channel architecture of QSFP lends itself to increase distances supported by multi-lane serial I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output electrical interconnects like PCI Express A high-speed peripheral interconnect from Intel introduced in 2002. Note that although sometimes abbreviated "PCX," PCI Express is not the same as "PCI-X" (see PCI-SIG and PCI-X for comparison). As a result of the confusion, "PCI-E" or "PCIe" is the accepted abbreviation. (PCIe) and Infiniband. Benefits of QSFP --Port Density nearly 3x higher than SFP module; Uses approximately same front panel space as XFP module --Support of Ethernet, Fibre Channel, InfiniBand and SDH/SONET with data rates up to 5Gb/s per channel --Transceiver Package and Electrical/Optical Connectors derived from designs currently in production --Industry first Z-pluggable parallel optics transceiver module with multi-vendor support About the QSFP MSA: The QSFP MSA welcomes feedback on the specification.
