Network Transceiver for 10G Copper Links

The SFP-10G-RJ45-A3R is an SFP+ transceiver with an RJ-45 port that auto-negotiates 10G, 5G, 2.5G and 1G speeds. It fits standard SFP+ cages in switches, routers, NAS units or NICs and draws less than 2.5 watts. The module is new and weighs 0.041 kilograms.

Hot-Swap RJ-45 Adapter with Auto-Sensing

No driver installation or configuration is required; the transceiver is hot-swappable so it can be inserted or removed while the network is live. It supports Cat.6a or Cat7 cabling with a reach of 98 feet at 10G or 5G and 328 feet at 2.5G or 1G. A robust enclosure helps protect against electromagnetic interference in dense racks.

Suits Multi-Speed Copper Uplinks Not Proprietary

Network operators who need flexible 10G-to-1G copper links on compatible Cisco, Ubiquiti, Netgear, Fortinet, D-Link, TP-Link, Linksys, Edge-core, Intel, EMC, Meraki, FS, Norkia, QTC, Broadcom, Supermicro or open switches will benefit. It is not suited for buyers whose gear is limited to HP-ProCurve, HP-H3C, HP-Aruba, Arista, Mellanox, Dell Force10, Extreme, Brocade or Juniper ports, nor for the Ubiquiti US-48-500W model.

Questions about this item

Will the Realtek RTL8261C chip need firmware updates or replacement over time?

The module is a passive transceiver with no user-serviceable firmware; the chip is sealed inside and requires no maintenance beyond keeping the RJ-45 port clean.

What is the first limit reached when running 10 GbE continuously over Cat6a?

The 30-metre reach limit for 10 GbE and 5 GbE is the first constraint; beyond that distance the link drops to lower speeds.

How much heat and power does the module draw when left running all day?

Power consumption stays below 2.5 watts, and the operating temperature range spans -10 °C to 70 °C, so heat output remains low in continuous use.
