BlueOptics Direct Attach Cable SFP-STACK-15 10GBASE-CR, 2 m, copper twinax

BlueOptics Direct Attach Cable SFP-STACK-15 is a 2 meter copper twinax assembly engineered for 10GBASE-CR short-reach connections between SFP+ ports. This fixed cable integrates the connector ends and copper twinax conductor to deliver a low-latency, 10 Gbps link without separate optical transceivers. The compact design and direct-attach form factor make it suitable for dense rack environments, server-to-switch links, switch stacking, and other short-range 10GbE interconnects where a cost-effective, plug-and-play solution is required.

Advantages

The cable provides a simple plug-and-play connection that eliminates the need for separate transceivers, reducing component count and power consumption. As a copper twinax assembly it offers low latency and stable throughput for short distances while keeping acquisition and operational costs lower than optical alternatives. Its 2 m length supports flexible deployment in typical rack and cabinet layouts while preserving signal integrity for 10 Gbps links.

Suitable for

• Server-to-switch connections in data centers
• Switch-to-switch stacking and short-range aggregation links
• Top-of-rack and end-of-row 10GbE interconnects
• Environments where low latency and reduced power consumption are important

Key specifications

• Standard: 10GBASE-CR over copper twinax
• Data rate: 10 Gbps
• Length: 2 m (fixed assembly)
• Connector type: SFP+ direct-attach interface
• Cable medium: copper twinax
• Application: short-reach server, switch and stacking connections

How to use

Install the Direct Attach Cable by inserting each SFP+ connector into the corresponding SFP+ port on network devices until the latch engages. Ensure both devices are powered and configured for 10GbE operation; the link will typically be detected automatically by modern switches and servers. Route the cable within the rack to avoid sharp bends and mechanical strain, keeping the length consistent with the 2 m specification and maintaining proper airflow around equipment.

Usage recommendations

For reliable performance, avoid tight bends and excessive pulling force on the cable. Use in ambient conditions and rack layouts that match device specifications, and verify firmware or driver compatibility for SFP+ direct-attach modules on the connected equipment. For distances beyond the short-reach range, consider optical transceivers with fiber cabling.
