Tyco Electronics Corp. has released a quad small form-factor pluggable (QSFP) interconnect system that offers three times the density of traditional SFP ports and supports speeds up to 10Gbps per channel. This four-channel package is suitable for switches, routers and host bus adapters.

The QSFP product family includes cages, connectors and copper cable assemblies for a complete solution, developed within the QSFP Multi-Source Agreement (MSA).

Enhanced EMI springs
The cages feature enhanced EMI springs that contain EMI between both cage-to-bezel and cage-to-module interfaces. They are available with options for riding heat sinks similar to product developed for the XFP MSA Group and light pipes. The cages use press-fit technology for board termination and can be used in belly-to-belly (double-sided) applications. An XFP-style gasket can also be supported to maintain the cage opening behind the bezel. All QSFP cages will accept either copper cables or optics modules.

The 38-position, 0.8mm-pitch QSFP surface-mount connector is part of Tyco's Everclear product family--which includes connectors designed for Mini-SAS/serial ATA applications--and is designed for high-speed signal integrity. QSFP copper cable assemblies are a low-cost option for short-reach applications. Tyco is also releasing both active and passive cable assemblies to support Fibre Channel, Infiniband and Ethernet protocols. The backshells include a positive latching system, and the cables feature a pull-to-release tab.
