10Gb SFP+ to RJ45 Module 100m - Low Power 2W Copper Transceiver

In this review the author tested a 10Gb SFP+ to RJ45 copper transceiver aimed at network engineers and small IT teams who need a budget-friendly way to add 10G copper links. The bottom line: it delivers true 10Gb connectivity over copper with low power draw, wide compatibility and practical diagnostics, making it useful where fiber is unnecessary or too costly. The review focuses on real-world interoperability, thermal behaviour and ease of use when plugged into 10G SFP+ ports on equipment such as Ubiquiti gateways and 10G NICs.

Key Features

• Built-in Broadcom chip: ensures stable 10G signalling and reliable auto-negotiation with common 10G SFP+ hosts.
• Low power consumption: rated Max. Power Consumption 2W, which keeps the module cooler than higher power alternatives during sustained transfers.
• 100m copper reach: supports links up to 100m over Cat 6a/7 or better cable, allowing 10G over standard structured cabling for many offices.
• Hot-swappable design: plugs into a 10Gb SFP+ port without powering down the host, simplifying maintenance and upgrades.
• Link diagnostics: built-in cable monitoring and loopback/testing modes help identify physical layer issues quickly.
• Standards compliant: SFF-8431 MSA and IEEE 802.3az/802.3an compliance improves interoperability across switches and NICs.

Who It's For

Network administrators provisioning 10G links between switches, gateways and servers who prefer copper runs over short distances will find this module practical. It is especially suitable for retrofitting 10G into existing Cat 6a/7 infrastructure and for labs or small data closets where low power draw and thermal performance matter.

It is not intended for long-haul fiber links or environments that require factory optical isolation; buyers who must exceed the 100m copper limit or need specialized optical transceivers should look elsewhere.

Pros & Cons

Pros

• Good compatibility with Ubiquiti UF-RJ45-10G style ports and common 10G NICs, enabling plug-and-play operation.
• Runs cooler thanks to low power usage, which users reported improves sustained performance in racks.
• Useful diagnostics and loopback modes make troubleshooting cable or link problems straightforward.
• 100m reach on Cat 6a/7 keeps copper viable for many office deployments without changing cable plant.

Cons

• Performance depends on cable quality; to reach full 10G reliably you need Cat 6a/7, and results may vary with older Cat5e runs.
• The module is designed for copper short-reach applications only and cannot replace fiber transceivers where optical links are required.

Our Verdict

This 10Gb SFP+ to RJ45 transceiver is a pragmatic choice for teams that need straightforward 10G copper links with low power draw and proven interoperability with Ubiquiti-style gear. It offers solid diagnostics and a compact metal package at a reasonable cost, making it a good value for office and small data closet deployments when staying within the 100m copper limit.

Frequently Asked Questions

Will this module work in Ubiquiti 10G SFP+ ports?
Yes, it is designed to be compatible with Ubiquiti UF-RJ45-10G type ports and similar 10G SFP+ interfaces and is tested for interoperability.

What cable do I need to reach 100m?
Use Cat 6a or Cat 7 cabling to achieve 10G up to 100m; older Cat5e may work shorter distances but is not guaranteed for full 100m at 10G.

Can I hot-swap the module?
Yes, the transceiver is hot-pluggable so it can be inserted or removed without powering down the host device.
