ALLNET ALL4759V2-2 DAC Cable 2m SFP+

The ALLNET ALL4759V2-2 2m SFP+ DAC cable is a direct attach copper interconnect designed for short-reach, high-speed links in networking environments. With SFP+ interfaces on both ends and a 2-meter length, this cable supports 10 Gigabit Ethernet connections between switches, servers, and storage devices. Its factory-terminated assemblies reduce the need for transceivers and simplify rack cabling while delivering low latency and consistent signal integrity for data center and enterprise installations.

Advantages

This DAC cable provides a cost-effective solution for high-bandwidth connections where short distances and low power consumption are required. The SFP+ connectors ensure wide compatibility with common networking equipment that accepts SFP+ direct-attach cables. The robust copper construction and molded connector housings enhance mechanical durability and reduce the risk of signal degradation over time. The pre-terminated design minimizes installation time and eliminates the need for separate optical transceivers, lowering overall system power usage.

Suitable for

• 10 Gigabit Ethernet links between switches in rack environments
• Direct connections between servers and storage arrays within the same rack or adjacent racks
• Short-reach links in data center top-of-rack and middle-of-row deployments

Key specifications

• Connector type: SFP+ on both ends
• Cable length: 2 meters
• Transmission medium: Direct attach copper (DAC)
• Supported data rate: 10 Gbps (SFP+ standard)
• Typical use: Short-reach interconnects within racks or between adjacent racks
• Form factor: Pre-terminated twinax cable assembly with molded connectors

How to use

To install, insert each SFP+ connector into the corresponding SFP+ port on the networking devices until the latch engages. Ensure devices are powered down or ports are administratively disabled if required by your installation policy, then enable the ports and verify link status through device management interfaces. No transceiver modules are necessary; the cable functions as the complete physical link. Keep bend radius within manufacturer-recommended limits and avoid sharp kinks to maintain signal integrity.

Recommendations

For reliable operation, use this 2m SFP+ DAC cable for connections within the same rack or between adjacent racks where distances do not exceed 2 meters. Verify compatibility with your switch and server ports and confirm link speed and duplex settings in device firmware or management software. Store and route the cable to avoid excessive bending and mechanical stress.
