SFP+ Direct Attach Cable BlueOptics 10GBASE-CR 2 m (1200484G2-BL)

BlueOptics SFP+ Direct Attach Cable 10GBASE-CR, 2 m is a copper twinax cable designed for short-reach 10 Gbit/s connections between SFP+ ports. The cable provides a direct-attach alternative to fiber transceivers for rack- and chassis-level interconnects, enabling low-latency links between compatible switches, servers and network interface cards. Its 2 metre length is suited to inter-rack and intra-rack connections inside data centres and server rooms where a fixed, cost-effective 10G connection is required.

Advantages

The direct attach cable offers low latency and low power consumption compared with active optical links. As a copper twinax solution it reduces cost per port and simplifies installation by providing a plug-and-play SFP+ form-factor connection. The fixed length minimizes cable management complexity and helps maintain signal integrity for short-distance 10GBASE-CR links.

Suitable for

• Short-reach 10 Gbit/s connections inside racks
• Interconnects between switches and servers in data centres
• Direct links to network interface cards with SFP+ ports
• Patch and aggregation connections in server rooms

Key specifications

• Interface: SFP+ direct-attach (copper twinax)
• Rated speed: 10 Gbit/s (10GBASE-CR)
• Length: 2 m
• Cable type: Passive twinax copper
• Typical use: Short-reach, rack-level interconnects
• Plug form factor: SFP+ compatible

How to use

Insert each SFP+ connector into the SFP+ port of the devices to be connected, ensuring secure seating until the retention latch engages. Verify that both devices support 10GBASE-CR over passive direct attach copper cables and that firmware or driver compatibility requirements are met. After insertion, confirm link status via device LEDs or management interfaces and proceed with normal network configuration.

Usage recommendations

For reliable operation, use the cable for distances up to 2 m in controlled rack environments, avoid sharp bends and excessive pulling force, and keep connectors free of dust. Do not use outside specified short-reach scenarios; for longer distances or environments requiring electrical isolation, consider optical SFP+ transceivers and fiber cabling.
