SFP+ Direct Attach Cable BlueOptics ET5402-DAC-1M 10GBASE-CR, 1 m, passive

The SFP+ Direct Attach Cable BlueOptics ET5402-DAC-1M 10GBASE-CR is a 1-m passive twinax copper cable with fixed SFP+ connectors. It is intended for short-reach 10 Gbit/s links between network equipment that supports SFP+ ports, such as switches, servers and network interface cards. The cable offers low-latency, low-power connectivity in a compact, plug-and-play SFP+ form factor for data center and rack-level interconnections.

Advantages

This passive SFP+ direct attach cable provides a cost-effective alternative to optical transceivers for short-distance 10G connections. It delivers high data throughput with minimal latency and reduced power consumption compared with active optical solutions. The fixed SFP+ form factor ensures compatibility with devices that accept SFP+ ports and enables straightforward installation without additional configuration. Its 1 m length is suitable for connections within racks or between adjacent racks where reliable, high-speed copper interconnects are required.

Suitable for

• Short-reach 10G links between switches
• Direct connections from servers to top-of-rack switches
• Interconnects between network interface cards (NICs) and switches
• Low-latency links in data center rack environments

Key specifications

• Interface: SFP+ fixed connectors (copper twinax)
• Data rate: 10 Gbit/s (10GBASE-CR)
• Length: 1 meter
• Type: Passive direct attach cable (twinax copper)
• Typical use: Short-reach, rack-level interconnects

How to use

Install the cable by inserting each SFP+ connector into the corresponding SFP+ port on the devices to be connected (for example, a switch and a server). Ensure that both devices support 10G SFP+ copper direct attach connections and that the ports are powered down or adhere to hot-plug procedures recommended by the equipment manufacturer. After insertion, the link should establish automatically; verify the connection status via device LEDs or management interfaces and adjust network settings as required.

Usage recommendations

For reliable operation, use this 1 m passive SFP+ cable within short rack distances and avoid excessive bending or strain on the twinax cable. Confirm device compatibility with copper SFP+ modules and follow your switch or server vendor guidance for hot-plugging and link negotiation. If longer distances or optical isolation are required, consider fiber-based SFP+ optics instead.
