Product Overview

The 10G SFP+ Active DAC Twinax Cable (FOT-DAC-10G-A) is a factory-terminated active direct attach copper assembly linking one 10G SFP+ port to a SFP+ port, delivering full 10G throughput over 30/28 AWG twinax copper at distances of up to 10 m. Active signal conditioning at both ends extends copper reach beyond passive limits while keeping cost well below optics.

Each assembly ships terminated, serialized and 100% traffic-tested: eye-diagram and BER verification on every lane, connector housings inspected, and EEPROM programmed to your requested vendor coding so the cable is recognized natively by your switches and NICs.

OEM branding, custom lengths and mixed-coding ends (different vendor coding on each end) are all supported with short lead times.

Platform Compatibility

Every cable is EEPROM-programmed at the factory to the vendor coding you specify, so it is recognized natively — no "unsupported transceiver" warnings, no console workarounds. Mixed coding (a different vendor on each end) is available for inter-vendor links.

Quality & What's in the Box

100% Traffic Tested

Every lane BER-verified end-to-end on live traffic before packing; eye diagrams sampled per batch.

Serialized & Traceable

Unit serial number links to test record, coding profile and production batch for full traceability.

Test Report Included

Per-order test report available on request; sample reports provided for tender documentation.

Packaging

Individually bagged with pull-tab protector caps, coiled to safe bend radius, export cartons.

Typical Applications

Data Center Fabrics

Spine-leaf and top-of-rack links inside and between adjacent racks.

AI / GPU Clusters

High-radix accelerator fabrics where cost per port and power per bit decide the BOM.

HPC & Storage

InfiniBand-class latency for compute and NVMe-oF storage backends.

Enterprise Core

Cost-effective uplinks between aggregation and core switching layers.

Frequently Asked Questions

When should I choose an active DAC over a passive one?

Choose active when the run exceeds passive copper limits (usually 3–5 m) but you still want copper economics — an active DAC reaches 7–10 m at a fraction of AOC cost. Beyond ~10 m, move to an AOC.

Will it work with my switch brand?

Yes — tell us your platform when ordering and we program the EEPROM with the matching vendor coding (NVIDIA/Mellanox, Cisco, Arista, Juniper, Huawei, HPE or open MSA). Mixed coding on the two ends is available for inter-vendor links.

What are your MOQ and lead time?

Standard configurations ship in 3–7 days with flexible MOQ. Custom OEM/ODM runs are quoted per project — send us your specs for a fast quotation.
