Add-On SFP-28G-PDAC1-5M-RD-AO 5M 25G DAC Cable

Overview

The Add-On SFP-28G-PDAC1-5M-RD-AO is a 5-meter passive Twinax direct attach cable designed for 25 Gigabit Ethernet (25GbE) connections. It terminates in SFP28 connectors on both ends, enabling direct, short-reach interconnects between network devices like switches, servers, and storage arrays. Its passive design means it draws power directly from the host ports, simplifying installation and reducing potential points of failure. This cable is TAA (Trade Agreements Act) and MSA (Multi-Source Agreement) compliant, ensuring it meets specific government procurement and industry standards for interoperability and sourcing.

Compatibility

This cable is compatible with any network equipment featuring SFP28 ports that support 25GBASE-CR standards. This includes a wide range of enterprise switches, data center switches, and server network interface cards (NICs) from various manufacturers that adhere to the SFP28 MSA. It is designed for direct connection between two SFP28 ports, such as switch-to-switch or server-to-switch configurations within a rack or adjacent racks.

Installation Notes

Connectors should be firmly seated into the SFP28 ports on both devices. Ensure the cable is not subjected to excessive bending radius (typically > 50mm) to maintain signal integrity. The passive nature of this cable means it requires no external power source. Verify that both connected devices are configured for 25Gbps operation. The 5-meter length is suitable for intra-rack or adjacent rack connections in data center environments.
