SFP+ Direct Attach Cable BlueOptics JW102A 10GBASE-CR, 3 m

SFP+ Direct Attach Cable BlueOptics JW102A 10GBASE-CR, 3 m is a 3-metre copper twinax assembly designed for short-reach 10 Gigabit Ethernet links. The cable provides a direct SFP+ form-factor connection between devices with SFP+ ports, offering a low-latency, fixed 10G interface without the need for separate optical transceivers. It is intended for rack-to-rack, top-of-rack and server-to-switch interconnects where cost-effective, high-throughput cabling is required.

Advantages

The direct attach cable delivers deterministic latency and lower power consumption compared with optical transceivers plus fiber, and its integrated SFP+ connectors simplify installation. Being a purpose-built twinax copper link for 10GBASE-CR, the cable offers consistent electrical performance for short-distance links and reduces component count in the network path. The 3 m length balances reach and cable management for data center topologies.

Suitable for

• Short-reach 10 Gigabit Ethernet interconnects between switches
• Server-to-top-of-rack and rack-to-rack connections
• High-density switch stacks and blade server networks
• Environments where low latency and low power are required

Key specifications

• Interface: SFP+ to SFP+ direct attach (twinax copper)
• Standard: 10GBASE-CR (10 Gigabit Ethernet over direct-attach copper)
• Length: 3 metres
• Data rate: 10 Gbit/s
• Cable type: Shielded twinax copper suitable for short-reach links
• Connector form factor: SFP+ compatible

How to use

Install the SFP+ Direct Attach Cable by inserting each SFP+ connector into the SFP+ ports of the devices to be connected until the latch engages. Verify link status on both endpoints and confirm negotiated 10 Gbit/s operation in the device interface settings. Route the cable to avoid sharp bends and excessive strain; maintain recommended bend radius for twinax copper. For redundant links, use separate cable paths and ports as defined by your network design.

Usage recommendations

Use this 3 m twinax SFP+ cable for short-distance connections inside racks or between adjacent racks. Avoid using it for long-span runs or in situations requiring optical isolation. Check device compatibility with SFP+ passive/direct-attach assemblies and follow vendor guidance for firmware or port settings when necessary.
