BLUEOPTICS Compatible Coriant QSFP28-4SFP28-DAC-2M BlueLAN Passive 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28 Direct Attach Breakout Cable, 2 Meter, AWG26

The BLUEOPTICS Compatible Coriant QSFP28-4SFP28-DAC-2M is a high-performance passive Direct Attach Copper (DAC) breakout cable designed for reliable 100 Gigabit Ethernet connectivity. This cable converts a single QSFP28 port into four independent SFP28 ports, enabling seamless integration into Coriant (Nokia) systems. With a length of 2 meters and 26 AWG gauge, it offers a cost-effective and energy-efficient solution for short-range interconnects in data centers and high-performance computing environments.

Advantages

This breakout cable provides significant advantages over active optical cables, including lower power consumption (less than 0.5W per end), reduced latency, and superior signal integrity. Its passive design ensures plug-and-play simplicity without the need for external power. The cable is fully compliant with IEEE 802.3bj, SFF-8665, and SFF-8402 standards, guaranteeing interoperability with standard QSFP28 and SFP28 ports.

Suitable for

• Data center interconnects (Top-of-Rack to Server)
• High-performance computing (HPC) clusters
• Network switches and routers requiring 100G to 4x25G breakout
