SFP+ DAC 10G Direct Attach Copper Twinax Cable for Direct Equipment Connection, 3 m

The SFP+ DAC 10G Direct Attach Copper (Twinax) Cable is designed for high-speed direct connections between networking devices with data rates of up to 10 Gbps. Equipped with two integrated SFP+ connectors, the cable provides a reliable and cost-effective connection between switches, servers, routers, storage systems, and other networking equipment without requiring separate optical transceivers.

Direct Attach Copper (DAC) technology utilizes a high-quality shielded Twinax copper cable, delivering low latency, low power consumption, and stable high-speed data transmission. With a length of 3 meters, this cable is an ideal solution for short-distance interconnections inside server racks, data centers, telecommunications rooms, and enterprise network environments.

Key Features

• Data rates up to 10 Gbps for 10 Gigabit Ethernet applications.
• 3-meter cable length — ideal for short-range equipment interconnections.
• Integrated SFP+ connectors eliminate the need for separate optical transceivers.
• Twinax copper cable provides low signal loss and reliable performance.
• Low power consumption compared to optical connectivity solutions.
• Ultra-low latency for high-performance networking applications.
• Plug & Play installation with no additional configuration required.
• Broad compatibility with networking equipment supporting the SFP+ interface.

How It Works

A DAC cable integrates two SFP+ transceiver interfaces into a single shielded Twinax copper cable. Unlike fiber optic solutions, it transmits electrical signals directly through the copper conductor without requiring lasers or optical fiber.

This design provides:

• high-speed data transmission;
• ultra-low latency;
• easy installation;
• reduced power consumption;
• lower overall network deployment costs.

Applications

• data centers;
• server rooms;
• network racks and cabinets;
• switch-to-server connections;
• switch-to-switch interconnections;
• storage area networks (SAN);
• enterprise networking;
• 10 Gigabit Ethernet infrastructure.

Technical Specifications

Installation Recommendations

1. Verify that both networking devices are equipped with compatible SFP+ ports.
2. Insert one end of the cable into the first SFP+ port.
3. Connect the opposite end to the second compatible device.
4. Check the LINK indicator to confirm a successful connection.
5. Avoid excessive bending of the cable during installation.

Frequently Asked Questions

How is a DAC cable different from a fiber optic patch cord?

A DAC cable includes integrated SFP+ transceiver modules, eliminating the need for separate optical transceivers and fiber patch cords.

What transmission distance is this cable designed for?

This DAC cable is intended for short-range connections within server racks, server rooms, and data centers. The cable length is 3 meters.

Does the cable require an external power supply?

No. The cable operates directly through the connected SFP+ ports and requires no external power source.

Is the cable compatible with all SFP+ equipment?

The cable is compatible with most networking devices supporting the SFP+ 10G interface. Some manufacturers may require vendor-coded compatible DAC cables.

When should a DAC cable be used instead of fiber optics?

DAC cables are the preferred solution for short-distance connections where low latency, low power consumption, easy installation, and cost efficiency are important.
