Cabo breakout Direct Attach BlueOptics Q28-4S28-DAC-1M-QL-BL compatível com Qlogic QSFP28 para 4x SFP28, 1m, passivo, 100GBASE-CR4/25GBASE-CR, AWG26

The BlueOptics Q28-4S28-DAC-1M-QL-BL is a high-performance, passive Direct Attach Copper (DAC) breakout cable designed for reliable 100 Gigabit Ethernet connectivity. This cable converts a single QSFP28 port into four independent SFP28 ports, enabling seamless integration of 100G switches with 25G servers or storage devices. With a length of 1 meter and AWG26 gauge, it offers a cost-effective, low-latency solution for data center and high-performance computing environments.

Advantages

This breakout cable eliminates the need for separate transceivers and fiber cabling, reducing cost and complexity. Its passive design ensures zero power consumption and ultra-low latency, while the robust copper construction provides excellent signal integrity over short distances. The cable is hot-swappable and fully compatible with Qlogic equipment, ensuring plug-and-play operation.

Suitable for

• Data center top-of-rack (ToR) to server connections
• High-performance computing (HPC) clusters
• Enterprise network upgrades to 100G/25G
