BlueOptics Compatible Broadcom QSFP28-4SFP28-DAC-1M BlueLAN Passive 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28 Direct Attach Breakout Cable, 1 Meter, AWG26

The BlueOptics Q28-4S28-DAC-1M-BC-BL is a high-performance passive Direct Attach Copper (DAC) breakout cable designed for 100 Gigabit Ethernet applications. It converts a single QSFP28 port into four independent SFP28 ports, enabling cost-effective connectivity for data center and enterprise networks. Fully compatible with Broadcom equipment, this cable delivers reliable 100GBASE-CR4 to 4x25GBASE-CR links over a 1-meter length.

Advantages

This breakout cable offers a simple, low-power solution for high-speed interconnects. Its passive design ensures zero latency and no power consumption, while the copper construction provides excellent signal integrity. The 1-meter length is ideal for short-reach connections within racks, reducing cable clutter and improving airflow.
