10GBASE-T Copper SFP+ Transceiver, Multi-Rate RJ45 100M to 10G
The EdgeOptic 10G-SFP-T is a copper SFP+ transceiver with an RJ45 interface that delivers 100M, 1G, 2.5G, 5G, and 10G Ethernet over CAT6a or CAT7 twisted-pair cabling up to 30 m. Multi-rate auto-negotiation under IEEE 802.3u, 802.3ab, 802.3bz, and 802.3an lets a single module replace separate Fast Ethernet, Gigabit, and 10 Gigabit access uplinks, which makes the 10G-SFP-T a practical fit for top-of-rack switch ports, server NICs, Wi-Fi 6 and 6E AP backhaul, legacy 100 Mbps endpoints, and copper-based brownfield deployments where pulling new fibre is not an option.

10GBASE-T Copper RJ45 SFP+ Transceiver Description
The EdgeOptic 10G-SFP-T is a multi-rate 10GBASE-T SFP+ copper transceiver with a standard RJ45 connector, supporting 100BASE-TX, 1000BASE-T, 2.5GBASE-T, 5GBASE-T, and 10GBASE-T Ethernet over twisted-pair cabling. Auto-negotiation selects the highest common rate the host switch and link partner agree on, so the same module can serve a 10 Gbps server uplink today and step down to 2.5 Gbps for a Wi-Fi 6 access point, or all the way to a 100 Mbps legacy endpoint, on the next port without manual reconfiguration. Reach is 30 m on certified CAT6a or CAT7 cabling in the standard 0 to 65 degrees Celsius case-temperature range, drawing power from a single +3.3 V SFP+ host rail at a typical 2.3 W. Maximum supply current is 900 mA, with a worst-case power draw of 3.0 W stated across the full voltage and temperature range. The module is hot-pluggable and presents a standard SFP+ electrical interface, so it slots into any RJ45-capable cage without a host-side firmware change beyond enabling the appropriate port speed.
Typical deployments are top-of-rack and end-of-row switch ports, server-to-switch links that reuse existing structured copper, multi-gig RJ45 fan-out from SFP+ access switches, Wi-Fi 6 and 6E access-point uplinks that need the 2.5 GbE or 5 GbE NBASE-T rates, NAS connections that run faster than 1 GbE without justifying a fibre install, and brownfield 10G migrations where the building's CAT6a plant rules out new fibre runs. The 10GBASE-T PHY runs hotter than short-reach optical SFP+ or passive DAC because it actively cancels echo and crosstalk on all four pairs, which is why a copper SFP+ module sits in a higher SFP+ power class than a typical SR optical transceiver. Verify the host switch's per-port and aggregate SFP+ power budget, and confirm 10GBASE-T support in the switch transceiver matrix, before populating every cage with copper modules. Switches engineered around lower-power optical SFP+ may need rate or population limits in mixed deployments.
Standards conformance covers IEEE 802.3an for 10GBASE-T, IEEE 802.3bz for 2.5GBASE-T and 5GBASE-T (NBASE-T and MGBASE-T), IEEE 802.3ab for 1000BASE-T, IEEE 802.3u for 100BASE-TX, IEEE 802.3ae for the underlying 10GbE SFP+ host interface, the SFP MSA mechanical and electrical specification, and INF-8074i. The 10G-SFP-T is CE and RoHS certified. The module ships with multi-vendor EEPROM coding, so it presents the correct vendor identity to the host switch and removes the third-party transceiver warning on platforms that key on EEPROM contents. For the cable plant, CAT6a is required to reach the full 30 m at 10GBASE-T, and CAT7 or better cabling also satisfies the 10GBASE-T channel requirement; CAT5e and CAT6 are not rated for the module's 10GBASE-T distance. At the module's lower NBASE-T rates, the datasheet rates CAT5e for 50 m at 5GBASE-T and 2.5GBASE-T and 100 m at 1000BASE-T.

Frequently Asked Questions
Does the 10G-SFP-T require Cat 6a or Cat 7 cabling, or will Cat 6 work?
The 10G-SFP-T is specified for 30 m over Cat 6a or Cat 7. Cat 6 is not rated for the module's 30 m reach at 10GBASE-T. IEEE 802.3an permits 10GBASE-T on Cat 6 up to 55 m in fully compliant installations, but the alien-crosstalk margin is narrow and real-world Cat 6 runs often fall short due to termination workmanship and bundled-cable interference. For reliable 10 Gbps links at 30 m, specify Cat 6a or Cat 7 and certify the channel with a Cat 6a-capable cable tester before commissioning.
How much power does the 10GBASE-T SFP+ module draw, and will it overheat in a fully populated switch?
10GBASE-T SFP+ modules draw considerably more power than short-reach optical SFP+ or passive DAC. The 10G-SFP-T draws a typical 700 mA, about 2.3 W, at the nominal 3.3 V supply rail. Its maximum supply current is 900 mA, and its worst-case power draw is 3.0 W stated across the full voltage and temperature range; use the 3.0 W figure when budgeting per-port power in a fully populated switch. Optical SFP+ transceivers consume under 1 W and passive DAC is effectively zero, while 10GBASE-T adds active equalisation and echo cancellation across all four pairs, which is why it runs hotter. The 10G-SFP-T operates within a 0 to 65 degrees Celsius case-temperature range and relies on host-switch airflow to stay inside that envelope. Switches that fully populate every SFP+ port with copper modules can exceed the platform's thermal and SFP+ power budget, so verify the host's per-port and cumulative SFP+ power-class rating before specifying more than a handful of 10GBASE-T modules in the same chassis.
Does the 10G-SFP-T link at 2.5GbE and 5GbE, or only at 1G and 10G?
The 10G-SFP-T supports 100BASE-TX under IEEE 802.3u, 2.5GBASE-T and 5GBASE-T under IEEE 802.3bz, alongside 1000BASE-T and 10GBASE-T. Auto-negotiation selects the highest common speed supported by both ends; in most deployments no manual rate configuration is required for 100 Mbps legacy ports, 2.5 GbE NAS ports, 5 GbE NICs, or Wi-Fi 6 and 6E access-point uplinks. Some switch firmwares do require the SFP+ port speed to be pinned to match the partner device, so confirm multi-gig behaviour against the host switch release notes. The full set of supported rates is 100 Mbps, 1 Gbps, 2.5 Gbps, 5 Gbps, and 10 Gbps.
What actual reach should I plan for, and how does cable grade or installation quality affect the 30 m specification?
The 30 m specification assumes correctly terminated Cat 6a or Cat 7 with quality patch cords and low ambient electromagnetic interference. Real-world reach is governed by cable quality, patch-panel termination workmanship, and EMI in the cable path. At 30 m on a fully certified Cat 6a run, expect clean 10 Gbps operation. Longer runs approaching the IEEE 802.3an maximum of 100 m are outside the 10G-SFP-T module specification. For deployments at the distance limit, certify the channel with a Cat 6a-capable tester before commissioning. See the knowledge base article Cat 6 vs Cat 6a vs Cat 7 for 10GbE for a full cable-grade comparison.
