BlueOptics Molex 74764-1201 Compatible BlueLAN QSFP+ Direct Attach Copper Cable, 2m, 40Gbps, Passive, 30 AWG, Black

40 Gbps of raw throughput over a 2-meter passive copper link—this BlueOptics QSFP+ DAC cable delivers high-density interconnect performance without the cost or complexity of optical transceivers. Engineered for Molex 74764-1201 compatible environments, it meets QSFP+ MSA SFF-8436 specifications and supports 40 Gigabit Ethernet, InfiniBand QDR/FDR, and Fibre Channel protocols. Ideal for top-of-rack switching, HPC clusters, and enterprise data centers where latency and power budgets are tight.

Overview

The BlueOptics BlueLAN QSFP+ Direct Attach Copper cable is a passive twinax assembly terminated with QSFP+ connectors on both ends. It provides a reliable, low-power 40Gbps connection over 2 meters, using 30 AWG conductors and a durable PVC jacket. The cable is fully compliant with the QSFP+ MSA and RoHS, ensuring seamless interoperability with Molex 74764-1201 and other MSA-compliant QSFP+ ports. With a power consumption of less than 0.5W, it significantly reduces energy costs compared to active optical cables.
