40Gbps High-Speed Ethernet Connectivity

The 40G DAC Cable 1M is designed for network environments that require substantially higher bandwidth than traditional Gigabit Ethernet connections.

With an advertised 40Gbps connection rate, it is suitable for supported 40GbE interfaces used in enterprise networking, server infrastructure, and high-capacity switching environments.

This makes the cable useful for applications involving large volumes of network traffic, including server communications, network aggregation, and connections between compatible core switches.

Typical applications include:

• Connecting compatible 40GbE switches.

• Establishing high-speed server-to-switch links.

• Supporting short-distance data centre connectivity.

• Linking compatible core and aggregation network equipment.

• Connecting network interface cards to supported switches.

The actual throughput of a connection depends on the capabilities of the connected devices, port configuration, network traffic, and protocol overhead.

The cable does not automatically upgrade a 10Gbps port to 40Gbps. Both endpoints must support the intended connection mode.

Direct Attach Copper Technology

Direct Attach Copper technology provides a practical way to connect high-speed networking equipment over short distances.

A DAC assembly uses copper conductors with integrated connector modules. Unlike a conventional fibre optic link, it does not require separate optical transceivers or fibre patch cords.

This construction is especially useful in server rooms and data centres where switches and servers are positioned close together.

Reduced Networking Components

Using a compatible DAC cable removes the need to purchase and install separate optical transceivers for each end of the connection.

This simplifies the components required for short-distance networking.

Convenient Installation

Compatible DAC assemblies can be inserted directly into the appropriate networking ports without fibre termination or separate optical modules.

However, successful operation depends on the compatibility of the cable and both connected devices.

Cost-Effective Short-Distance Connections

For nearby equipment, DAC connectivity can offer a more economical alternative to using two optical transceivers and a fibre optic patch cable.

The overall cost advantage depends on equipment compatibility, the type of DAC assembly, and the alternative optical components being considered.

Efficient Network Design

Passive DAC cables generally consume less power than comparable optical solutions. However, this specific 40G DAC Cable 1M has not been independently confirmed as passive, so its power characteristics should not be assumed.

QSFP+ Interfaces and Network Compatibility

Standard 40G Ethernet DAC cables commonly use QSFP+ interfaces to connect supported switches, routers, and server network interface cards.

A typical 40G QSFP+ to QSFP+ DAC assembly provides a direct connection between two compatible 40 Gigabit Ethernet ports.

However, the presence of a QSFP+ port does not guarantee compatibility with every third-party DAC cable. Some manufacturers implement compatibility checks or require specific cable coding.

Equipment Commonly Used with 40G DAC Cables

Depending on the actual connector configuration and manufacturer compatibility, 40G DAC assemblies can be used with:

• Enterprise switches equipped with compatible 40GbE ports.

• Data centre switches supporting QSFP+ DAC connections.

• Servers with supported 40GbE network interface cards.

• Routers with compatible 40GbE interfaces.

• High-capacity network aggregation equipment.

Before purchasing the cable, check the specifications of both networking devices to confirm that the required DAC connection is supported.

A standard QSFP+ to QSFP+ DAC cable is different from a QSFP+ to four SFP+ breakout cable. If your installation requires connecting one 40GbE interface to four 10GbE interfaces, you must purchase the appropriate breakout cable and confirm that the switch supports that configuration.

1 Metre Cable Length for Compact Installations

The 1-metre length makes this DAC cable especially suitable for connecting equipment located close together.

In enterprise server rooms and data centres, properly sized interconnection cables help improve rack organisation and reduce unnecessary cable slack.

A short cable can also make it easier for technicians to identify physical connections during installation and maintenance.

Suitable Installation Locations

• Network switches installed within the same rack.

• Servers positioned near a top-of-rack switch.

• Compatible core and aggregation switches in a network cabinet.

• High-speed network interfaces in compact server rooms.

• Short-distance equipment connections in data centres.

Before installation, measure the route between the two ports rather than relying only on the straight-line distance.

Allow enough cable length for connector insertion, cable management, and the manufacturer's permitted bend radius. Avoid excessive bending or tension that could damage the cable assembly.

For longer connections, a different cable length or an appropriate fibre optic solution may be more suitable.

What to Check Before Buying 40G DAC Cable 1M

Choosing the correct cable is important because not all 40G DAC assemblies are interchangeable.

1. Confirm the network port type

Check that both devices provide interfaces compatible with the cable being supplied. Standard 40G DAC cables commonly use QSFP+ connectors.

2. Verify switch and server compatibility

Review your equipment manufacturer's supported cable list. Some networking devices require compatible identification coding or specific DAC models.

3. Check the cable length

Ensure that 1 metre is sufficient for the intended installation, including the routing path and acceptable bending clearance.

4. Confirm the connector configuration

Determine whether your installation requires a standard 40G-to-40G connection or a breakout configuration.

5. Check passive or active construction

Some networking equipment specifies supported cable types. Confirm whether the supplied assembly is passive or active.

6. Request the exact product model

For compatibility-sensitive installations, confirm the manufacturer part number and applicable technical documentation before ordering.

If you are purchasing for a Cisco, MikroTik, Juniper, Arista, Dell, or another enterprise networking platform, compatibility should be confirmed using the exact device model rather than the brand name alone.
