BLUEOPTICS Compatible Planet 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-PT-BL is a high-performance passive direct attach breakout cable designed for reliable 100 Gigabit Ethernet connectivity. This cable converts a single QSFP28 port into four SFP28 ports, enabling cost-effective and efficient network upgrades. Compatible with Planet Systems equipment, it delivers full 100Gbps aggregate bandwidth over a 1-meter length with 26 AWG copper construction.

Advantages

This breakout cable offers a simple, low-power solution for connecting 100G QSFP28 switches to 25G SFP28 servers or storage. Its passive design ensures zero latency and high signal integrity, while the breakout configuration maximizes port utilization and reduces cabling complexity. The cable is hot-pluggable and RoHS compliant, ensuring easy installation and environmental responsibility.
