Networking cables Cisco

4XIB SuperFlex Cable DDR Ready, 3m Cisco is the worldwide leader in networking for the Internet. Cisco provides the broadest line of solutions for transporting data, voice and video within buildings, across campuses, or around the world. Cisco solutions ensure that networks both public and private operate with maximum performance, security, and flexibility.

Most data centers are designed and implemented to accommodate Category 5 or 6 copper and fiber optic cabling. Because these cables have a relatively small diameter and are reasonably flexible, maintaining a minimum bend radius is relatively simple and equipment cabinets can be positioned side-by-side with little or no space between them. As is typically used within the data center, Category 5 or 6 copper inter-rack cabling may be routed across overhead cable management systems up to 100 meters.
InfiniBand cable presents a challenge within this environment because the cables are considerably thicker, heavier, and shorter in length to mitigate the effects of cross-talk and signal attenuation and achieve low bit error rates (BERs). To assure the operational integrity and performance of the HPC cluster, it is critically important to maintain the correct bend radius, or the integrity of the cable can be compromised such that the effects of cross-talk introduce unacceptable BERs.
To address these issues, it is essential to thoroughly plan the InfiniBand implementation and provide a good cable management solution that enables easy expansion and replacement of failed cables and hardware. This is especially important when InfiniBand 12X or DDR technologies are being deployed because the high transmission rates are less tolerant to poor installation practices.
