Key Features

10GBASE-CU passive twinax cable
SFP+ to SFP+ terminations (copper)
Compatible with HP J9281D devices
Designed for short-reach data center links
Passive electrical design — no external power
Low-latency, deterministic copper interconnect

Preserve critical 10 Gbps connectivity without adding expensive optics. This AddOn Networks compatible cable implements 10GBASE-CU passive twinax copper with SFP+ terminations, designed for short-reach server and switch interconnects where electrical DACs reduce cost and port density overhead. It is sold as a compatible replacement for the HP J9281D family, providing vendor-flexible deployment options in mixed-vendor racks. The passive twinax design requires no external power or configuration, delivering deterministic latency and consistent signal integrity across copper interconnects. Choose this cable when you need reliable, low-latency links between 10G SFP+ ports and want to avoid the recurring expense of transceivers and fiber patching for very short distances. Note: verify platform compatibility with your switch or server vendor before purchase.

Ideal For

Connect 10G SFP+ NICs to top-of-rack switches for short-reach links
Link adjacent rack servers without fiber transceivers
Replace failed or lost vendor DACs in multi-vendor racks
Implement low-latency links for virtualization hosts and storage nodes

Why This Product

1Lower per-port cost than fiber plus transceivers in short runs
2No external power or optics compared with active DACs
3Vendor-compatible replacement for HP J9281D family
4Better latency and determinism than fiber over short distances

Frequently Asked Questions

Is this cable compatible with HP J9281D ports?▾

This AddOn Networks cable is sold as compatible with HP J9281D family SFP+ ports. Validate firmware and vendor compatibility in your switch or server before deployment.

Can I use this cable for long-distance connections?▾

No. Passive twinax SFP+ DACs are intended for short-reach links within racks or adjacent racks. For longer distances use fiber with appropriate transceivers.

Does the cable require additional power or configuration?▾

No. Passive twinax DACs are electrically passive and require no external power or user configuration; they appear as standard SFP+ ports to the host.

Are there latency differences versus fiber transceivers?▾

Passive twinax copper links typically produce lower, more deterministic latency than fiber plus transceivers for short-reach links, making them suitable for latency-sensitive server interconnects.
