10Gtek SFP to RJ45 1000Base-T Copper Ethernet Module - Pack of 10

In this review the 10Gtek SFP to RJ45 1000Base-T copper module is assessed as a practical, budget-minded transceiver for network admins and small labs that need reliable Gigabit links over copper. The bottom line: it is for anyone who needs a plug-and-play SFP to RJ45 adapter that supports up to 1.25Gb/s and runs over CAT.5e to 100m, and the single biggest reason to buy is its broad compatibility with common vendor SFP ports, making it an inexpensive way to add copper uplinks to switches and appliances.

Key Features

• Data rate: Delivers up to 1.25Gb/s to support Gigabit Ethernet traffic when paired with compatible switch ports.
• RJ-45 interface: Provides a standard copper port so devices with SFP cages can use inexpensive CAT.5e cabling.
• Cable reach: Supports transmission up to 100 meters over CAT.5e, covering typical office and rack distances without fiber.
• Vendor compatibility: Built to work with many common modules including Cisco GLC-T/SFP-GE-T and Meraki MA-SFP-1GB-TX for straightforward replacement or expansion.
• Pack quantity: Sold in a pack of 10, which makes it convenient for multiple ports or rollout projects and reduces per-port cost.

Who It's For

This module suits small IT teams, home lab enthusiasts, and installers who need a reliable copper SFP option to connect switches, routers, NAS devices and access points. It is especially useful when equipment has SFP cages but the installation calls for standard RJ-45 cabling and runs under 100 meters.

Those who require multi-gig speeds beyond 1Gbps, specialized optical links, or strict OEM warranty coverage from a specific switch vendor should look elsewhere, since this module targets standard Gigabit copper connectivity rather than 10Gbps fiber or proprietary, vendor-branded optics.

Pros & Cons

Pros

• Compatible with many major SFP vendors, offering broad interoperability for mixed networks.
• Plug-and-play installation makes deployment fast and uncomplicated for everyday use.
• Good value when bought as a pack of 10, lowering per-port cost for larger deployments.
• Works with common devices such as Synology NAS and UDM Pro Max according to customer feedback.

Cons

• Limited to 1.25Gb/s copper speeds, so it is not suitable for 10Gbps backbones.
• Some users report occasional low upload speeds in specific setups, so testing in your environment is recommended.

Specifications

Our Verdict

The 10Gtek SFP to RJ45 1000Base-T module is a practical, cost-effective solution for adding Gigabit copper ports to devices with SFP cages. It is recommended for IT pros and home lab users who need broad compatibility and simple installation; buying the pack of 10 makes it particularly good value for rollouts where 1Gbps copper is sufficient.
