Cisco 100Mb/1Gb/10Gb Ethernet RJ-45 SFP+ Transceiver Module

The Cisco SFP-10G-T-X= is a plug-in SFP+ transceiver module that converts a compatible Cisco switch or router port into a copper Ethernet link capable of running at 100 megabit, 1 gigabit, or 10 gigabit per second. It uses an RJ-45 interface and maintains reliable connections over twisted-pair copper cabling up to 328 feet, allowing you to increase bandwidth without installing new fiber.

The module draws just 2.5 watts, helping reduce heat and power costs in dense network racks. Installation is straightforward: slide the unit into an open SFP+ slot, attach the cable, and the link establishes automatically across 100Base-TX, 1000Base-T, or 10GBase-T standards.

Network teams often choose this transceiver when upgrading campus wiring closets, branch offices, or small data centers where existing copper infrastructure must support higher speeds. Its operating range from -5 °C to 85 °C keeps the link stable in network rooms that may experience wide temperature swings, including lightly conditioned warehouses and industrial edge sites.

The design complies with IEEE 802.3 and ITU-T G.709 specifications, ensuring dependable interoperability with other Ethernet equipment and predictable performance under demanding workloads.
