BlueOptics Ciena Compatible QSFP28-4SFP28-DAC-2M Passive Direct Attach Breakout Cable, 2m, AWG26

The BlueOptics Q28-4S28-DAC-2M-CI-BL is a high-performance passive Direct Attach Copper (DAC) breakout cable designed for Ciena compatible networking equipment. It provides a cost-effective and low-power solution for 100 Gigabit Ethernet connectivity by breaking out a single QSFP28 port into four independent SFP28 ports, each operating at 25 Gbps. This cable is ideal for short-range interconnects within data centers and high-performance computing environments.

Advantages

This passive DAC cable offers zero power consumption, eliminating the need for external power sources and reducing overall system heat. Its breakout design maximizes port utilization and simplifies cable management by consolidating four 25 Gbps links into one 100 Gbps connection. The cable is hot-pluggable, allowing for easy installation and replacement without powering down the system. With a length of 2 meters and AWG26 gauge, it provides reliable signal integrity for short-distance connections.

Suitable for

• Data center top-of-rack to server or switch interconnects
• High-performance computing clusters
• Enterprise networking upgrades to 100G
• Ciena compatible switches and routers
