BlueOptics Cabo Breakout Direct Attach Passivo BlueLAN 100GBASE-CR4 QSFP28 para 4x25GBASE-CR SFP28 IBM QSFP28-4SFP28-DAC-1M compatível, 1 metro, AWG26

The BlueOptics Q28-4S28-DAC-1M-IB-BL is a high-performance passive copper direct attach breakout cable designed for 100 Gigabit Ethernet applications. It converts a single QSFP28 port into four independent 25 Gigabit SFP28 links, providing a cost-effective and low-power solution for data center interconnects. Compatible with IBM and other standard QSFP28/SFP28 equipment, this cable ensures seamless integration and reliable data transmission over a 1-meter length.

Advantages

This breakout cable offers significant advantages over active optical cables or transceivers: lower power consumption (typically less than 0.5W), reduced latency, and a more affordable price point. The passive copper design requires no external power and is hot-pluggable, making it easy to deploy and maintain. With 26 AWG wire gauge, it provides excellent signal integrity for short-reach connections within racks or between adjacent racks.

Suitable for

• Data center top-of-rack to server connections
