BlueOptics MCP7F00-A002-BL QSFP28 to 4x SFP28 Passive Direct Attach Copper Breakout Cable, 2m, Black

The BlueOptics MCP7F00-A002-BL is a high-performance QSFP28 to 4x SFP28 passive direct attach copper (DAC) breakout cable, designed for data centers and high-performance computing environments. It provides a cost-effective and reliable solution for connecting 100 Gb/s QSFP28 ports to four 25 Gb/s SFP28 ports, supporting InfiniBand EDR and 100GbE Ethernet protocols.

Advantages

This breakout cable offers significant advantages in terms of flexibility and cost savings. By breaking out a single 100 Gb/s QSFP28 port into four 25 Gb/s SFP28 connections, it enables efficient utilization of existing infrastructure and simplifies cable management. The passive design ensures low power consumption (<0.5 W) and high reliability, while the 2-meter length provides ample reach for rack-to-rack or within-rack connections.

Suitable for

• Data center interconnects
• High-performance computing (HPC) clusters
• Enterprise networking
