Network Cable BlueOptics Direct Attach Cable 10GBASE-CR SFP+ 0.5 Meter Black

The BlueOptics Direct Attach Cable 10GBASE-CR SFP+ 0.5 Meter Black is a short-range, high-performance copper twinax cable engineered for reliable 10 Gigabit Ethernet links. With SFP+ terminations and a compact 0.5 m length, the cable provides low-latency, high-throughput connectivity between switches, servers and storage devices in dense rack environments. Its industrial-grade construction ensures consistent signal integrity for 10GBASE-CR applications while minimizing clutter and preserving airflow in data centers and enterprise wiring closets.

Advantages

This direct attach cable offers native SFP+ compatibility for plug-and-play deployment without additional transceivers, delivering reduced cost per port and simplified cabling management. The short, fixed length lowers insertion loss and crosstalk compared with longer copper assemblies, while the robust jacket and connector housings provide mechanical stability and reliable mating cycles in high-use environments. The cable's design supports stable 10 Gbit/s operation with low latency suitable for latency-sensitive applications.

Suitable for

• Interconnects between SFP+ ports on switches and servers within the same rack or adjacent racks
• Top-of-rack aggregation and short-distance fabric links in data centers
• High-density networking setups where space-saving cabling is required
• Environments requiring predictable 10G copper connectivity without transceivers

Key specifications

• Interface: SFP+ to SFP+
• Data rate support: 10 Gbit/s (10GBASE-CR)
• Length: 0.5 meter
• Cable type: Twinax copper direct attach
• Connector type: SFP+ metal housing
• Typical use: Short-range, high-density interconnects

How to use

Insert each SFP+ connector into the corresponding SFP+ port on network equipment until the latch engages. Ensure both devices support 10GBASE-CR over direct attach copper and that port settings (speed and duplex) are configured as needed by your network. Route the cable to avoid sharp bends and maintain recommended bend radius to preserve signal integrity. For rack installations, secure excess length to prevent strain on connector ends.

Usage recommendations

Verify device compatibility with SFP+ direct attach copper cables before installation. Use the 0.5 m length for intra-rack or adjacent-rack links to minimize signal loss. Avoid repeated mating cycles beyond rated connector life and protect connectors from dust when not in use. For environments requiring longer reach or optical isolation, consider fiber-based SFP+ modules instead.
