BlueOptics Compatible Alcatel-Lucent QSFP28-4SFP28-DAC-2M BlueLAN Passive 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28 Direct Attach Breakout Cable, 2 Meter, AWG26 (Q28-4S28-DAC-2M-AL-BL)

The BlueOptics Q28-4S28-DAC-2M-AL-BL is a high-performance passive Direct Attach Copper (DAC) breakout cable designed for reliable 100 Gigabit Ethernet connectivity. It converts a single QSFP28 port into four SFP28 ports, enabling cost-effective 100G to 4x25G breakout applications in data centers and high-performance computing environments. This cable is fully compatible with Alcatel-Lucent equipment and MSA compliant QSFP28/SFP28 ports.

Advantages

This breakout cable offers a simple, low-power, and cost-effective solution for high-speed network interconnects. By utilizing passive copper technology, it ensures zero latency and minimal power consumption compared to active optical cables. The 2-meter length with 26 AWG gauge provides flexibility for rack-to-rack or rack-to-switch connections while maintaining signal integrity.

Suitable for

• Data center top-of-rack to server connections
• High-performance computing clusters
