BlueOptics NVIDIA 980-9I48T-00C02A BlueLAN SC282701L3M26 Passive 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28 Direct Attach Breakout Cable, 3 Meter

The BlueOptics NVIDIA 980-9I48T-00C02A BlueLAN SC282701L3M26 is a high-performance passive Direct Attach Copper (DAC) breakout cable designed for data center and enterprise networking environments. It provides a cost-effective and low-latency solution for connecting 100GbE QSFP28 ports to four 25GbE SFP28 ports, enabling seamless migration to higher bandwidths.

Advantages

This breakout cable offers significant advantages over traditional transceivers and fiber cabling. It consumes zero power (passive design), reduces cable clutter, and provides reliable, low-latency connectivity for high-density deployments. The cable is hot-pluggable and fully compliant with IEEE 802.3bj and 802.3by standards, ensuring interoperability with NVIDIA (formerly Mellanox) equipment and other compatible switches, routers, and servers.

Suitable for

• Data center top-of-rack (ToR) and end-of-row (EoR) switch interconnects
• Server-to-switch connections requiring 100G to 4x25G breakout
• High-performance computing (HPC) clusters
• Storage area networks (SAN) and cloud infrastructure
