An SFP transceiver delivering 1 Gbps over copper to 100 m with industrial temperature rating
This transceiver plugs into any SFP port that accepts the 10/100/1000BASE-T standard and provides a single RJ-45 jack for copper cabling. It is built for network engineers who need to extend a switch or router over standard twisted-pair links up to one hundred metres. The module is fully MSA compliant and verified for Cisco equipment.
Rated for operation from minus five to eighty-five degrees Celsius, the unit stays within specification inside unheated cabinets or outdoor enclosures. Digital diagnostic monitoring reports temperature, voltage and bias current in real time so administrators can spot thermal drift before a link fails. Power draw remains modest, keeping aggregate chassis loads predictable.
When a deployment only needs Gigabit speed over Cat5e or Cat6, this copper SFP removes the cost and fragility of fibre patch cords and matching optics. The jump is worth it for campus links, building-to-building bridges or data-centre top-of-rack connections that stay inside the hundred-metre reach. It is not suited for links that exceed that distance or require single-mode fibre.

Slide the module into an SFP port until the latch clicks, then insert the RJ45 patch cable fully until it locks; the step often missed is removing the dust plug from the transceiver before cabling.
The transceiver itself has no moving parts or replaceable components; only the RJ45 patch cables may wear and need replacement if the latch breaks or contacts corrode.
The operating temperature ceiling of 85 °C is the first limit; sustained heavy traffic in a poorly ventilated chassis can push the module toward that threshold.
