Huawei 1.5m SFP+ to SFP+ Direct Attach Copper Cable, 10G Passive Twinax, Stacking & Interconnect

This Huawei SFP+ direct attach cable delivers a dependable 10 Gigabit Ethernet link over a 1.5-meter passive twinax assembly. Engineered for switch stacking, server-to-switch connectivity, and storage area networks, it provides a low-latency, low-power alternative to optical transceivers. The cable integrates two SFP+ connectors and complies with IEEE 802.3ae 10GBASE-CR, ensuring broad compatibility with Huawei and MSA-compliant equipment.

Advantages

Passive twinax design consumes less than 0.1 W per end, reducing operating costs and heat. The 30 AWG conductors and 100 Ohm impedance maintain signal integrity across the full 1.5 m length. Hot-swappable connectors allow for quick installation or replacement without downtime. The PVC jacket and wide operating temperature range (0°C to 70°C) support deployment in standard data center and wiring closet environments.

Suitable for

• Stacking multiple Huawei switches to create a unified logical switch
• Connecting servers with SFP+ ports to top-of-rack switches
• Linking storage controllers and disk arrays in SAN environments
• Short-reach 10GbE interconnects where fiber is unnecessary
