HPE 537963-B21 Direct Attach Copper Cable

Overview

The HPE 537963-B21 is a 5-meter direct attach copper cable designed for high-speed network connections. It terminates with SFP+ connectors on both ends, enabling 10Gbps data transfer rates. This cable is suitable for short-reach interconnects within racks or between adjacent racks in data centers, server rooms, or network closets where high bandwidth is critical. Its 24AWG construction and PVC (OFNR) jacket ensure reliable performance and compliance with plenum-rated environments.

Compatibility

This SFP+ cable is compatible with any network device featuring SFP+ ports, supporting protocols such as 10 Gigabit Ethernet, Fibre Channel, and InfiniBand (QDR, DDR, SDR). It adheres to the SFF-8665 standard, ensuring broad interoperability with SFP+ transceivers and host systems from various manufacturers. Verify your specific switch, server, or network interface card (NIC) has SFP+ ports for successful integration.

Installation Notes

The cable features a minimum bend radius of 30mm, requiring careful routing to avoid kinks that could impede signal integrity. The jacket material is PVC rated OFNR (Optical Non-Routine), suitable for vertical runs in non-plenum spaces. Operating temperature range is 0 to 70°C. Crosstalk is limited to 2% maximum, and the time delay is 1.31 nsec/ft, ensuring predictable performance in demanding environments.
