BlueOptics Q28-4S28-DAC-1M-AO-BL Compatible Avago QSFP28 to 4x SFP28 Direct Attach Breakout Cable, 1m, Passive, AWG26

The BlueOptics Q28-4S28-DAC-1M-AO-BL is a high-performance, passive direct attach breakout cable designed for data center and enterprise networking applications. It provides a cost-effective solution for connecting QSFP28 ports to four SFP28 ports, supporting 100GBASE-CR4 on the QSFP28 end and 25GBASE-CR on each SFP28 end. This cable is fully compatible with Avago equipment and complies with MSA standards, ensuring seamless integration into existing networks.

Advantages

This breakout cable offers significant advantages in terms of cost, power efficiency, and ease of deployment. By eliminating the need for separate transceivers and fiber optic cabling, it reduces overall system cost and power consumption. The passive design ensures zero latency and high reliability, making it ideal for high-density environments. The 1-meter length with AWG26 gauge provides flexibility for rack-to-rack or intra-rack connections.
