High-Density DAC, AOC, and AEC Cables for Short and Mid-Range Interconnects

Trxcom provides a comprehensive selection of high-speed DAC (Direct Attach Copper), AOC (Active Optical Cable), and AEC (Active Electrical Cable) interconnects for top-of-rack (ToR) and rack-to-rack connectivity. Covering 10G, 25G, 40G, 100G, 200G, and 400G applications, our cable assemblies support QSFP28, QSFP-DD, SFP28, and OSFP interface types.

Passive DACs are ideal for short-range, low-power environments, while AOCs and AECs offer extended reach with active signal conditioning. All cables are factory pre-terminated and pre-tested, ensuring plug-and-play deployment with guaranteed signal integrity and compliance with IEEE and InfiniBand standards.

Whether you're connecting switches, NICs, or GPU servers, Trxcom’s interconnect portfolio provides cost-effective, latency-optimized solutions tailored for cloud, AI/ML, and enterprise use cases.

Frequently Asked Questions about DAC/AOC/AEC Cables

• Q: What is the difference between DAC and AOC cables?
  A: DAC (Direct Attach Cable) is a copper-based, low-cost solution for short-distance interconnects, while AOC (Active Optical Cable) uses fiber optics and supports longer distances with better EMI performance.

• Q: What are AEC cables used for?
  A: AEC (Active Electrical Cable) extends copper-based connectivity beyond the reach of passive DACs, typically up to 7-10 meters, using signal equalization and amplification.

• Are LINK-PP DAC/AOC cables compatible with QSFP28/QSFP-DD ports?
  A: Yes. LINK-PP pre-coded DAC and AOC cables are fully compatible with standard QSFP28, SFP28, and QSFP-DD port specifications from major vendors.
