Copper SFP transceiver delivers 10/100/1000BASE-T over RJ-45 up to 100 m with auto-negotiation and hot-pluggable operation
This copper SFP transceiver delivers 1.25 Gb/s data rates over RJ-45 using Cat.5 UTP cable up to 100 metres. It targets network engineers upgrading switches, routers or servers with copper Gigabit links in commercial temperature environments.
Installation is hot-pluggable and follows the SFP MSA form factor with auto-detect MDI/MDI-X on the RJ-45 port. The module requires host equipment that supports SGMII signalling; without the correct vendor coding it will not link, so the brand and model of the host must be supplied before ordering.
The transceiver handles 10/100/1000BASE-T traffic with 1000BASE-X and 1000BASE-T auto-negotiation on a single 3.3 V supply. It is not suited for fibre links, 10 GbE speeds or distances beyond 100 metres, and it cannot operate in hosts that lack SGMII support.

Check the host equipment port LEDs for a solid link light and confirm 1000Mbps negotiated speed in the switch or server management interface.
The transceiver ships alone; you must supply a four-pair Cat.5 UTP patch cable up to 100m and a compatible SFP slot with SGMII support.
Select the SGMII 10/100/1000T version; it auto-negotiates 10/100/1000 speeds and matches the host SGMII electrical interface.
