SFP to RJ45 Module 1000BASE-T Transceiver - Pack of 4 for Gigabit

In this review of the SFP to RJ45 Module, the bottom line is simple: this pack of four 1000BASE-T copper transceivers is for anyone who needs a reliable, low-cost way to add RJ45 Gigabit ports to switches or servers that accept SFP modules. The reviewer found them straightforward to use, broadly compatible with open switches and major brands, and effective for connecting NAS, SAN, or standard Gigabit Ethernet links up to 100m over CAT.5e. For shops that need hot-pluggable flexibility without vendor lock-in, these modules deliver the core capability you need.

Key Features

• 1000BASE-T data rate: Provides full Gigabit Ethernet connectivity at 1.25Gb/s for common network workloads.
• RJ45 connector: Lets SFP slots accept standard copper Ethernet cables so legacy copper runs can be reused without new hardware.
• 100m reach: Supports copper links up to 100m over CAT.5e, which covers typical office and rack-to-rack distances.
• Wide compatibility: Designed to work with many open switches and models like Cisco, Ubiquiti, Netgear, TP-Link and more, reducing compatibility headaches.
• Plug-and-play design: Hot-pluggable construction and a rotatable ring latch make installation and removal quick and tool-free.
• After-sales support: Includes a 30-day free return and a 3-year warranty plus lifetime technical support for peace of mind.

Who It's For

This product is aimed at network administrators, small data center operators, and home lab enthusiasts who want to convert SFP or SFP+ ports to copper Gigabit without replacing switches or NICs. It is especially useful for setups that need occasional or permanent copper connectivity to NAS, SAN, or servers.

Those who should look elsewhere include users requiring multi-gigabit speeds beyond 1Gb or specialized fiber links; this module is strictly a 1000BASE-T copper transceiver and does not provide fiber optics or 10Gb performance.

Pros & Cons

Pros

• Affordable pack of four gives spare units for redundancy and quick replacements.
• Broad brand compatibility reduces the risk of vendor lock-in and makes migration simpler.
• Simple hot-plug operation and durable latch design make field swaps fast.
• Warranty and lifetime technical support add useful after-sales protection.

Cons

• Limited to 1.25Gb/s (1000BASE-T), so it will not enable multi-gig links above 1Gb.
• Does not add fiber connectivity; only RJ45 copper over CAT.5e is supported.

Our Verdict

The SFP to RJ45 Module pack is a pragmatic, cost-effective choice for anyone who needs to add or replace Gigabit copper ports via SFP slots; its wide compatibility and plug-and-play design make it good value for small networks, labs, and mixed-vendor environments where 1Gb performance is sufficient.

Frequently Asked Questions

Will these modules work in vendor-branded switches?
They are designed for broad compatibility with open switches and commonly work in many Cisco, Ubiquiti, Netgear, TP-Link and similar models, though specific firmware or vendor lock settings can affect compatibility.

What cable and distance can I use?
Use CAT.5e or better copper cable for reliable links up to 100m, which suits typical rack-to-rack or office runs.

Are these hot-swappable?
Yes, the transceivers are hot-pluggable and have a rotatable ring latch for easy insertion and removal without tools.
