BlueLAN Compatible Arista CAB-Q28-S28-1M Passive 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28 Direct Attach Breakout Cable, 1m, AWG26

The BlueLAN CAB-Q28-S28-1M-BL is a high-performance passive copper direct attach breakout cable (DAC) designed for compatibility with Arista networking equipment. It provides a cost-effective and reliable solution for high-speed data center interconnects, converting a single 100G QSFP28 port into four 25G SFP28 ports.

Advantages

This breakout cable simplifies cabling and reduces costs by eliminating the need for separate transceivers. It supports aggregate data rates of 100 Gbps, with each of the four lanes delivering 25 Gbps. The passive copper design ensures low power consumption and minimal latency, making it ideal for high-density environments.
