BLUEOPTICS Compatible Garland Technology QSFP28-4SFP28-Cable_1 BlueLAN 100GBASE-CR4 QSFP28 a 4x25GBASE-CR SFP28 Cable Direct Attach Breakout pasivo, 1m, AWG26 (QSFP28-4SFP28-Cable_1-BL)

The BLUEOPTICS QSFP28-4SFP28-Cable_1-BL is a high-performance passive direct attach breakout cable designed for 100 Gigabit Ethernet applications. It connects a QSFP28 port to four SFP28 ports, enabling cost-effective 100G to 4x25G connectivity in data centers and high-performance computing environments. This cable is fully compatible with Garland Technology equipment and meets industry standards for reliable data transmission.

Advantages

This breakout cable offers a simple, low-power solution for splitting a 100G QSFP28 interface into four 25G SFP28 links. It eliminates the need for separate transceivers and fiber cabling, reducing cost and complexity. The passive design ensures near-zero power consumption (<0.1W) and high reliability. With a length of 1 meter and AWG26 gauge, it is ideal for short-range interconnects within racks.

Suitable for

• Data center top-of-rack to server connections
