SFP+ Direct Attach Copper Cable Basical Information

Transceivers must be attached to a direct attach cable to travel to the other end of the module for communication. And here comes to the direct attach cable. The standard SFP+ direct attach cables are offered in different wire gauges depending on the length. The SFP+ cable assemblies are hot swappable and have a programmed EEPROM signature that enables the host to get the difference between the copper assembly cable and the fiber optic module. The cables have low power consumption making them quite economical.

The SFP+ dac is a fully hot pluggable direct attach cable that support 10Gigabit Ethernet and Fiber Channel applications that are connected through the Small Form Factor Pluggable ports. The cables are designed for the short length to offer high-speed interconnections with the use of low power. They are a low latency Twinax cables that are a cost effective alternative to the fiber optic cable assemblies and are intended for the point-to-point network switch/server connections.

The SFP+ direct attach copper cables are designed to meet the data center networking and high-performance computing applications that need a high-density cabling interconnection to facilitate the 10Gb/s transmission rates. They are designed to be fully compatible with the in form factor and the electrical connections, to meet all the requirements governing the Small Form Factor industry standards.
