BlueOptics Compatible Lenovo 7Z57A03564 BlueLAN Passive 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28 Direct Attach Breakout Cable, 1m, AWG26 (7Z57A03564-BL)

The BlueOptics 7Z57A03564-BL is a high-performance passive copper direct attach breakout cable (DAC) designed for reliable 100 Gbps connectivity in data centers and high-performance computing environments. This cable is fully compatible with Lenovo 7Z57A03564 and provides a cost-effective solution for breaking out a single QSFP28 port into four SFP28 ports, enabling seamless integration of 25 Gbps and 100 Gbps equipment.

Advantages

This breakout cable offers significant advantages over active optical cables or transceivers: lower power consumption, zero latency, and reduced cost. The passive copper design ensures reliable signal integrity over the 1-meter length, while the AWG26 wire gauge provides optimal flexibility and durability. Hot-pluggable connectors allow for easy installation and maintenance without network downtime.
