D-Link DGS-712

Overview

The D-Link DGS-712 is a copper Small Form factor Pluggable (SFP) transceiver module designed to add a Gigabit Ethernet RJ-45 port to switches or routers with an available SFP slot. It supports 1000BASE-T connectivity over standard Category 5 cabling, enabling network links up to 100 meters without the need for fiber installation. This module is hot swappable, allowing installation or removal without powering down the equipment, and it automatically negotiates speeds of 10, 100, or 1000 Mbps while supporting both straight-through and crossover cables through built-in MDI/MDIX functionality.

Key features

• Hot swappable design allows easy installation or replacement without interrupting network operation
• Automatic speed negotiation and MDI/MDIX support simplify network setup and compatibility with various cabling types
• Fully metallic enclosure shields sensitive components from electromagnetic interference, enhancing signal integrity
• Low power consumption reduces heat generation and energy costs, making it suitable for dense wiring environments
• Compliance with SFP Multi Source Agreement and RoHS standards ensures broad compatibility and environmental safety
• Supports standard Cat 5 or better cabling, allowing cost-effective network expansion without fiber upgrades

Key specs

• Standard: IEEE 802.3ab 1000BASE-T Gigabit Ethernet
• Interface: RJ-45 copper port
• Maximum cable length: 100 meters over Cat 5 or better
• Speed support: 10/100/1000 Mbps with auto negotiation
• MDI/MDIX: Automatic crossover detection and correction
• Form factor: Small Form factor Pluggable (SFP)
• Housing: Fully metallic enclosure for EMI protection
• Power consumption: Low power dissipation design

Connectivity and compatibility

This transceiver module fits into any standard SFP slot, making it compatible with a wide range of switches and routers that support SFP interfaces. Its RJ-45 port supports existing copper Ethernet infrastructure, allowing seamless integration into networks using Category 5 or higher cabling. The automatic MDI/MDIX feature eliminates the need for specific cable types, simplifying deployment in diverse environments.

Performance and reliability

The DGS-712 delivers stable Gigabit Ethernet performance with automatic speed negotiation to match connected devices. Its metallic housing reduces electromagnetic interference, which helps maintain signal quality in environments with multiple electronic devices. The low power design minimizes heat output, contributing to longer equipment lifespan and lower cooling requirements in network closets.

Ideal uses and environments

This module is well suited for data centers connecting top-of-rack switches to servers, enterprise networks linking edge switches to aggregation layers, and service providers requiring temporary copper links during maintenance or testing. Its ability to extend copper connections up to 100 meters without fiber makes it a practical and cost-effective solution for upgrading or expanding existing network infrastructure.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
