BlueOptics DAC-Q28-4SFP28-25G-2M Compatible BlueLAN QSFP28 DAC SC282701L2M26 InfiniBand Cable 4xSFP28 Black (DAC-Q28-4SFP28-25G-2M-BL)

The BlueOptics DAC-Q28-4SFP28-25G-2M is a high-performance passive direct attach copper (DAC) breakout cable designed for InfiniBand EDR and 100 Gigabit Ethernet applications. It connects a QSFP28 port to four SFP28 ports, providing aggregate data rates of 100 Gbps (4x25 Gbps per lane). This cable is compatible with BlueLAN QSFP28 modules and is ideal for high-speed data center interconnects.

Advantages

This breakout cable offers a cost-effective and low-power solution for high-bandwidth connections. Its passive design ensures zero power consumption, and the copper construction provides reliable signal integrity over the 2-meter length. The cable is hot-pluggable and complies with IEEE 802.3bj, SFF-8665, and SFF-8402 standards.

Suitable for

• Data centers requiring high-speed InfiniBand EDR or 100GbE connectivity
