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

The BlueOptics Q28-4S28-DAC-2M-NK-BL is a high-performance passive direct attach breakout cable designed for Nokia compatible networking equipment. It provides a cost-effective and low-power solution for high-speed data center interconnects, converting a single 100 Gbps QSFP28 port into four 25 Gbps SFP28 ports over a 2-meter copper cable.

Advantages

This breakout cable offers significant advantages over traditional transceivers and fiber cabling. It consumes less power, reduces latency, and provides a simpler, more reliable connection. The passive design ensures zero power consumption, while the breakout configuration maximizes port utilization and flexibility in top-of-rack or end-of-row architectures.
