BlueOptics SC282701L2M26-BL InfiniBand Breakout Cable 2m QSFP28 to 4x SFP28 Direct Attach Copper (DAC) Passive Black

The BlueOptics SC282701L2M26-BL is a high-performance InfiniBand breakout cable designed for demanding data center and high-performance computing (HPC) environments. This 2-meter passive Direct Attach Copper (DAC) cable features a QSFP28 male connector on one end and four SFP28 male connectors on the other, enabling seamless connectivity between 100GbE QSFP28 ports and four 25GbE SFP28 ports. It supports InfiniBand EDR and complies with SFF-8665 and SFF-8402 standards, ensuring reliable data transmission at aggregate speeds of up to 100 Gbps (25 Gbps per channel). The cable is hot-pluggable and comes in a sleek black color, making it ideal for high-density network setups.

Advantages

This breakout cable offers a cost-effective and efficient solution for splitting a high-speed QSFP28 port into four individual SFP28 connections. Its passive DAC design ensures low latency and zero power consumption, while the robust construction guarantees long-term durability. The cable is fully compatible with InfiniBand EDR and 100GBASE-CR4 standards, providing flexibility for various networking applications.
