BlueOptics Networks 10203 Compatible BlueLAN QSFP+ Direct Attach Cable (DAC) 3m Twinax Copper Passive 40GbE

Direct Attach Copper (DAC) cable delivering 40 Gigabit Ethernet over a 3-meter passive twinax assembly. The BlueOptics Networks 10203 provides four 10 Gbps lanes for an aggregate 40 Gbps, ideal for short-reach, high-density interconnects in data centers and HPC clusters.

Advantages

With 26 AWG twinax copper and passive design, power consumption stays below 0.5W, drastically reducing operating costs compared to active optical cables. The SFF-8436 compliant interface and 100 Ohm impedance ensure robust signal integrity across all four channels. Hot-pluggable QSFP+ connectors allow quick installation without downtime, and MSA compliance guarantees interoperability with BlueLAN and other vendor equipment.

Suitable for

• Top-of-rack to server connectivity in data centers
