BlueLAN Passive Direct Attach Breakout Cable, 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28, 3m, AWG26, Compatible with NVIDIA 980-9I48U-00C02A

The BlueLAN 980-9I48U-00C02A-BL is a high-performance passive copper direct attach breakout cable (DAC) designed for reliable 100 Gbps connectivity in data center environments. This cable breaks out a single QSFP28 port into four SFP28 ports, enabling seamless migration from 100G to 25G infrastructure. It is fully compatible with NVIDIA 980-9I48U-00C02A and other standard QSFP28/SFP28 interfaces.

Advantages

Passive design ensures zero power consumption and minimal latency. The breakout configuration allows efficient utilization of existing 25G equipment while supporting 100G aggregation. AWG26 gauge provides optimal signal integrity over 3 meters. Hot-pluggable connectors simplify installation and maintenance.

Suitable for

• Data center top-of-rack to server connections
• High-speed networking between switches and network interface cards
