D-Link 1000BASE-T Copper SFP Transceiver Module

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

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.
