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

The BlueOptics Q28-4S28-DAC-2M-MR-BL is a high-performance passive Direct Attach Breakout Cable (DAC) designed for seamless integration with Meraki networking equipment. This cable converts a single QSFP28 port into four SFP28 ports, enabling cost-effective 100G to 4x25G connectivity within data centers and high-performance computing environments. Built with 26 AWG copper and measuring 2 meters in length, it ensures reliable, low-latency transmission with minimal power consumption.

Advantages

This breakout cable offers a compact and efficient solution for upgrading network infrastructure without the need for additional transceivers. Its passive design ensures zero power draw, while the breakout configuration maximizes port utilization and reduces cabling complexity. The BlueLAN© series guarantees compatibility and performance, making it an ideal choice for high-density deployments.
