BlueOptics Compatible Ixia 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-IX-BL is a high-performance passive Direct Attach Copper (DAC) breakout cable designed for Ixia test equipment. It provides a cost-effective and reliable solution for 100 Gigabit Ethernet connectivity by breaking out a single QSFP28 port into four independent 25 Gigabit SFP28 links. With a length of 1 meter and AWG26 gauge, this cable ensures low latency and excellent signal integrity for data center and lab environments.

Advantages

This cable offers seamless compatibility with Ixia systems, ensuring plug-and-play operation without the need for configuration. The passive copper design consumes no power, reducing overall energy costs and heat generation. Its breakout configuration maximizes port utilization, allowing efficient connection of 25G devices to a 100G switch or tester. The robust construction guarantees long-term reliability and consistent performance.
