2.5GBASE-T Copper SFP Transceiver: 2.5G-SFP-T

The 2.5GBASE-T Copper SFP is an EDGE Optical Solutions transceiver built to the SFP MSA electrical and mechanical interface, delivering 2.5 Gigabit Ethernet over standard RJ45 twisted pair copper cabling. It runs the 2.5GBASE-T Ethernet application defined in IEEE 802.3bz, with a supported data rate range from 100 Mbps to 2.5 Gbps on Category 5 twisted pair cable, so a switch or router SFP cage can add a 2.5G copper uplink without moving to an SFP+ port or a fixed RJ45 interface. Like other SFP modules, it is hot-pluggable, so it can be inserted into or removed from a live host port without powering down the switch.

This module uses the standard SFP form factor, not SFP+. It is built for hosts with 2.5GBASE-T capable SFP cages. Confirm that the target switch or network interface card lists 2.5GBASE-T among its supported SFP rates before ordering, since not every SFP+ cage negotiates down to sub-10G copper rates automatically. Deployments that only need a fixed 1000BASE-T copper uplink are better served by a dedicated 1G copper SFP; this module is intended for sites that need multi-rate operation up to 2.5 Gbps.

IEEE 802.3bz and the NBASE-T signaling it defines were built to raise Ethernet rates above 1 Gbps over the same Category 5e cabling already installed for Gigabit Ethernet, instead of requiring a move to fiber. That design goal is why this module targets existing RJ45 copper plant rather than an optical interface.

Maximum distance is rated at 80 meters over Category 5 twisted pair copper. Actual usable reach depends on cable category, cable quality, and installation conditions. Consult the applicable cabling standard and the target switch documentation for category-specific distance guidance before planning longer runs.

Digital diagnostic monitoring is built in through the standard SFF-8472 DDM interface, reporting temperature and supply voltage so key operating parameters can be checked without extra test equipment. The module runs from a single +3.3V power supply and operates across a standard 0°C to 70°C temperature range suited to typical network closet and data center environments.

The module is built to the SFP MSA (INF-8074i) mechanical and electrical specification and IEEE 802.3bz for NBASE-T and MGBASE-T signaling, and it carries CE and RoHS marking. Following the standard SFP MSA electrical and mechanical interface gives it broad compatibility across SFP host ports that support 2.5GBASE-T. Verify the target switch or network interface card against its own supported-optics list before deployment, since 2.5G rate negotiation on SFP cages varies by vendor and firmware.

Verify 2.5GBASE-T support against the target switch or network interface card's supported-optics list before ordering. For volume pricing or deployment questions, contact our sales team.
