The electrical Small Form Factor Pluggable(SFP) transceiver module is specifically designed for the high performance integratedfull duplex data link at up to 1.25Gbps over four pair Category 5 UTP. The transceiver module is compliant with the SFP Multi-Source Agreement(MSA) and IEEE802.3:2002. With the hot pluggability, the module offers a flexible and easy way to be installed into SFP MSA compliant ports at any time without the interruption of the host equipment operating online. The 1000BASE-T electrical SFP transceivers use an integrated RJ-45 connector with transformer and PHY IC. The link length is up to 100m over four pair Category 5 UTP cabling. The applications include: Gigabit Ethernet over Cat 5 cable, Switch to switch SerDes or SGMII interface, Switched backplane application, and Media Converter.
