10G/25G/40G/50G ACC Cables

Simple, Low-Latency Links for Racks & Adjacent Racks

Overview

The NSComm 10G/25G/40G/50G Active Direct Attach Copper (ACC) family is a cost-effective, ultra-low-latency cabling solution for short-reach Ethernet connectivity between switches, servers, and storage. ACC uses twinax copper with integrated SFP/QSFP connectors, giving you a plug-and-play alternative to optical transceivers and fiber patch cords.

Compared with passive DAC, ACC adds active circuitry to support stable performance at higher speeds and longer short-reach runs-making it ideal for in-rack and adjacent-rack deployments across enterprise networks and data centers.

Broad Compatibility

NSComm ACC cables are designed for multi-vendor interoperability and can be ordered with selectable coding options to match different platforms. They integrate smoothly with common switch and NIC ecosystems, including:
Cisco, Huawei, Juniper, Arista, Dell, H3C, NVIDIA/Mellanox (Ethernet), Extreme, Intel, and more.

Product Range

This collection covers mainstream short-reach copper links and a practical breakout option:

1. 10G SFP+ ACC (up to 10m)

A reliable choice for server uplinks, access-to-aggregation links, and general 10G short runs.

2. 25G SFP28 ACC (up to 9m)

Built for high-density server-to-ToR connections and modern 25G data center access layers.

3. 40G QSFP+ ACC (up to 10m)

Used for switch-to-switch links in ToR/leaf environments and legacy 40G interconnects.

4. 40G QSFP+ to 4×10G SFP+ Breakout ACC (up to 9m)

Perfect when you need to fan out one 40G port into four 10G ports-common for migration projects and port expansion.

5. 50G SFP56 ACC (up to 7m)

Designed for 50G server uplinks and next-gen ToR deployments where you want more bandwidth without changing the physical footprint.

Key Benefits

• Ultra-low latency: Direct electrical connection with no optical conversion.

• Cost-effective: Fewer components than optics + fiber patching.

• Clean cabling: Plug-and-play assemblies reduce install time and failure points.

• Short-reach optimized: Ideal for in-rack and adjacent-rack links.

• Upgrade-friendly: Breakout option supports 40G-to-4×10G transitions.

• Multi-vendor ready: Selectable coding options for common switch/NIC platforms.

Buying Guide

• Match the speed to the port:

  • 10G for access and legacy uplinks

  • 25G for server-to-ToR mainstream data centers

  • 40G for legacy ToR/leaf interconnects or 10G fanout

  • 50G for newer server uplinks and higher-density racks

• Choose the interface: SFP+ / SFP28 / QSFP+ / SFP56 based on your hardware.

• Decide straight vs breakout: Use breakout when a single 40G port must connect to four 10G devices.

• Plan the run: ACC is best for within a rack or to the next rack, keeping cabling short and tidy.

• Get expert support: Share your switch/NIC models and topology-our certified engineers can confirm compatibility and best-fit lengths.

Conclusion

The 10G/25G/40G/50G Active Direct Attach Copper Cable Collection delivers practical, plug-and-play connectivity for short-reach links in enterprise networks and data centers. With multi-vendor options, ultra-low latency, and a breakout solution for 40G-to-10G transitions, NSComm ACC cables help you build cleaner, faster, and more cost-efficient rack connectivity.
