BlueLAN Cable Direct Attach SFP56 50GBASE-CR pasivo, 2 metros, compatible con NVIDIA 980-9I874-00G002

The BlueLAN 50GBASE-CR Passive SFP56 Direct Attach Cable (DAC) is a high-performance, cost-effective solution for short-range, high-speed data center and HPC interconnects. Designed as a compatible replacement for NVIDIA 980-9I874-00G002, this passive copper twinax cable delivers reliable 50 Gbps connectivity over a 2-meter length, ideal for top-of-rack to server connections.

Advantages

This passive DAC cable offers ultra-low power consumption (<0.1W) and zero latency, making it an energy-efficient alternative to active optical cables. Its SFP56 form factor ensures hot-pluggable installation and backward compatibility with SFP+ and SFP28 ports. The robust copper twinax construction provides excellent signal integrity and durability in high-density environments.
