IBM 90Y9428 – 3M PASSIVE SFP+ DAC CABLE

Detailed Description:

The IBM 90Y9428 is a 3-meter long Passive Direct Attach Copper (DAC) Cable specifically designed for use with the SFP+ (Small Form-factor Pluggable Plus) interfaces. This high-speed cable is engineered to facilitate short-range, high-speed interconnects between networking equipment like switches, routers, and servers. The SFP+ interface at both ends of the cable enables connections that support speeds of up to 10 Gbps, making it an ideal solution for data centers and high-performance computing environments where low latency and high bandwidth are critical. Unlike active DAC cables that require power to boost the signal, passive DAC cables like the IBM 90Y9428 rely solely on the equipment they connect to for signal integrity, making them more energy-efficient and cost-effective for shorter distances. The use of copper as a medium, although limiting the maximum distance due to signal degradation, ensures that this cable provides a robust and reliable connection with low latency, which is essential for applications requiring real-time data transfer. Furthermore, the plug-and-play nature of the SFP+ interface simplifies installation, and the cable’s compact, flexible design allows for easy routing through congested network cabinets. Overall, the IBM 90Y9428 DAC cable is a practical connectivity solution that combines high performance with simplicity and efficiency.
