Mellanox / NVIDIA-Compatible DAC, AOC & Transceiver Cables
This collection brings together high-performance passive DAC cables, active optical cables (AOC), and QSFP transceivers fully compatible with NVIDIA Mellanox switching and server platforms. Every cable is EEPROM-coded to the target platform, ensuring plug-and-play installation — no CLI overrides, no link-up headaches. From 25G SFP28 edge connections to 800G OSFP breakouts for next-generation AI fabric, Resilient Tec stocks the interconnects your infrastructure demands.

Passive DAC vs. AOC — Which Is Right for Your Rack?
Passive DAC cables are the lowest-latency, most cost-effective choice for short-reach connections (typically 1–3m) within the same rack or adjacent racks. They draw minimal power and introduce no additional electronics between endpoints. Ideal for top-of-rack switch-to-server connections and spine-leaf patching at short distances.
Active Optical Cables (AOC) use fiber optics with integrated optics in the connector housing, making them the right choice for longer intra-data-center runs (up to 100m+). AOCs provide EMI immunity and allow flexible routing through tight cable management, making them a strong choice for inter-rack and mid-row connections in high-density AI GPU clusters.
Breakout Cables for AI & High-Density Fabric
Breakout DAC cables allow a single high-speed port to fan out to multiple lower-speed endpoints — a critical capability in AI training clusters built on NVIDIA DGX and HGX systems. Our 800G OSFP to 4x200G and 200G QSFP56 to 2x100G breakout cables are specifically coded for NVIDIA Mellanox HDR and NDR switch platforms, enabling maximum port density at minimal cost per connection.
