OFFCUP A-4969751 10GBASE-T SFP+ RJ45 Copper Transceiver, up to 30m

Usage tips

For a network setup that needs an RJ45 copper connection from an SFP+ port, the OFFCUP 10GBASE-T transceiver provides a direct way to make that link. It supports data rates up to 10Gb/s and transmission distances up to 30m. Use it with suitable CAT6A or CAT7 cable for a copper connection. If your priority is to work with RJ45 cabling already in place, this is a different approach from building a fibre link.

The module is designed for plug-and-play integration and supports hot swapping, making it practical when installing or replacing a transceiver in a compatible switch without shutting down the network. To remove it, rotate the ring lock down 90° and pull the module from the switch. Digital diagnostics are also supported, giving the module a useful monitoring feature in network equipment.

Pros

A key benefit is the combination of an SFP+ module format and an RJ45 connector: it lets compatible equipment make a copper connection using the familiar network cable format. The stated reach of up to 30m suits links where that distance is sufficient, while support for 10Gb/s caters for high-speed network connections. The module also adapts downwards to 5G, 2.5G and 1G, which can help when the connected network setup uses one of those rates.

Compatibility is listed for equipment including Cisco SFP-10G-TS, Ubiquiti UF-RJ45-10G, Meraki MA-SFP-10G-T and Netgear AXM765, as well as D-Link, Edge-Core, Supermicro, Linksys, QNAP and Mikrotik devices. Check that the equipment has a compatible SFP+ port and that the specific device supports the module before installation. For a network that already uses copper RJ45 cabling, this can be a more direct fit than choosing a fibre transceiver and setting up a fibre link.

Practical questions

What cable should I use with this transceiver? It is intended for copper networking with an RJ45 connector and is listed as suitable for CAT6A or CAT7 cable. The stated transmission distance is up to 30m.

Can I use it with a 1G or 2.5G connection? The module is described as adapting downwards from 10G to 5G, 2.5G and 1G, as well as supporting a data rate of up to 10Gb/s.

Which equipment is it listed as compatible with? Listed examples include Cisco SFP-10G-TS, Ubiquiti UF-RJ45-10G, Meraki MA-SFP-10G-T and Netgear AXM765, alongside devices from D-Link, Edge-Core, Supermicro, Linksys, QNAP and Mikrotik. The host device needs a compatible SFP+ port.

Should you buy it?

Choose this OFFCUP module when you need to connect a compatible SFP+ port to an RJ45 copper network, particularly where CAT6A or CAT7 cabling is the practical choice. Its 10Gb/s capability, reach of up to 30m, downward rate adaptation and hot-swap support make it a useful fit for network installations that need a copper link without changing to a fibre-based approach.
