BlueOptics Molex 74764-2301 Compatible Breakout Direct Attach Copper Cable (DAC) Passive 40G to 4x10G QSFP+ to 4xSFP+ Twinaxial

The BlueOptics Molex 74764-2301 compatible breakout Direct Attach Copper (DAC) cable is a high-performance passive twinaxial copper solution designed for 40 Gigabit Ethernet to 4x10 Gigabit Ethernet connectivity. It features a QSFP+ connector on one end and four SFP+ connectors on the other, enabling seamless connections between switches, servers, and storage equipment in data centers and enterprise networks. This cable is ideal for rack-to-rack and adjacent rack interconnects, offering reliable, low-latency performance with minimal power consumption.

Advantages

This passive DAC cable provides a cost-effective and energy-efficient alternative to active optical cables or transceivers. With no active components, it consumes less than 0.5W per end and supports hot-pluggable installation. The breakout design allows a single 40G port to connect to four 10G devices, simplifying cabling and reducing costs. It is fully compatible with Molex 74764-2301 equipment and meets IEEE 802.3ba and 802.3ae standards.
