SFP+ cable BlueOptics JNP-SFP-DAC-2M-BL 2m plug/plug

The BlueOptics JNP-SFP-DAC-2M-BL is a 2 m SFP+ direct attach cable (DAC) designed for short-distance 10 Gbit/s connections between switches, servers and storage devices. It features SFP+ male connectors on both ends and a twinax copper construction suitable for 10GBase-CR, Ethernet, FCoE and Fibre Channel applications over a 2 meter span. The cable is MSA-compliant and intended for rack-to-rack or adjacent-rack links where passive DACs are supported.

Advantages

This passive SFP+ cable offers low latency and very low power consumption compared with active optical transceivers, and its twinax copper design provides reliable electrical transmission for short runs. Being MSA-compliant and built with industry-grade components, it delivers consistent compatibility with hardware platforms that support Juniper-style SFP+ DACs while providing a durable physical construction with a small, lightweight profile.

Suitable for

• 10 Gbit/s connections between switches and servers in data centers
• Rack-to-rack or adjacent-rack links within server rooms
• Storage-to-switch links for Ethernet, FCoE and Fibre Channel up to 10 Gbit/s
• Environments where low latency and low power consumption are required

Key specifications

• Cable length: 2 m
• Connectors: SFP+ male to SFP+ male
• Type: Passive twinax copper (DAC)
• Supported data rate: up to 10 Gbit/s
• Wire gauge: 30 AWG
• Colour: coral and silver
• Weight: 0.08 kg

How to use

Insert each SFP+ connector firmly into compatible SFP+ ports on the devices to be linked, ensuring the host hardware supports passive DACs. Verify link status in the device management interface and observe port negotiation for the intended 10 Gbit/s speed. Avoid sharp bends and excessive pulling; route the cable within rack channels or cable management trays to prevent stress on the connectors.

Recommendations

Use this 2 m passive SFP+ DAC for short, fixed connections inside racks or between adjacent racks. Confirm device compatibility with Juniper-style passive SFP+ DACs before deployment and keep the cable free from tight bends and mechanical strain to maximize service life.
