Deployment / Use Cases
This SFP+ direct attach cable is ideal for connecting servers, switches, and storage devices within the same rack or adjacent enclosures. Its 5-meter reach supports typical data center layouts where equipment is closely located, providing high-bandwidth links for virtualization, database clusters, and backup systems.
Common applications include linking IBM System x servers with 10Gb CNA cards to top-of-rack switches, establishing spine-leaf connections in compact networks, and upgrading existing 1GbE links to 10GbE without rewiring. The active design ensures performance in environments with potential electromagnetic interference.
Server-to-Switch Connectivity
Connect IBM System x servers equipped with 42C1800 or 42C1820 10Gb CNA cards to SFP+ switch ports for high-speed network access.
Data Center Inter-Rack Links
Establish 10GbE connections between adjacent racks for storage networks, hyper-converged infrastructure, or cluster communication.
Physical Profile
The cable features a slim, flexible twinaxial construction with a compact SFP+ connector footprint. With dimensions of 0.25" height and 0.50" width at the connectors, it fits densely populated SFP+ cages without obstructing adjacent ports. The 5-meter length provides ample reach for rack-to-rack or within-rack deployments, while the 10.24 oz weight minimizes stress on port latches.

User Manual
FAQ
What is the difference between active and passive direct attach cables?
Active direct attach cables like the AddOn 45W3039-AO include built-in electronics that amplify and condition the signal, allowing for longer reaches (up to 5-7 meters for 10GbE) and better performance in noisy environments. Passive cables have no electronics and are typically limited to shorter distances (up to 3 meters) as signal integrity degrades over length.
Is this cable compatible with non-IBM equipment?
While specifically tested and coded for compatibility with IBM System x 10Gb CNA cards (42C1800 and 42C1820), this SFP+ cable may work with other devices that support 10GBase-CU standard and SFP+ interfaces. However, compatibility is not guaranteed outside the listed IBM systems, and we recommend verifying with your equipment vendor.
What does TAA compliant mean for this product?
TAA (Trade Agreements Act) compliance indicates this cable meets U.S. government procurement requirements, meaning it is substantially manufactured or significantly transformed in a designated country. This makes it suitable for federal, state, and local government contracts, as well as educational and healthcare institutions that require TAA-compliant products.
Can I use this cable for distances longer than 5 meters?
No, this cable is designed for a maximum reach of 5 meters (approximately 16.4 feet). For longer distances, you would need fiber optic transceivers and cabling. The 10GBase-CU standard over twinax is optimized for short-reach applications within racks or between adjacent racks.
Does this cable support Digital Optical Monitoring (DOM)?
No, this is a direct attach copper cable (DAC) and does not include DOM/DDM capabilities. DOM is a feature typically found in fiber optic transceivers that provides diagnostic monitoring of temperature, voltage, laser bias, and optical power. This cable provides a simple electrical connection without optical components or monitoring.
What is the warranty on this direct attach cable?
The AddOn 45W3039-AO comes with a lifetime limited warranty, covering defects in materials and workmanship for the product's usable life. This warranty provides long-term assurance for network infrastructure investments, though it does not cover damage from misuse, improper installation, or unauthorized modifications.
