## Summary description

Direct attach cable (DAC) BlueOptics NDAAFF-0002 is a 2-meter copper twinax cable designed for 100GBASE-CR4 connections. It provides a fixed, low-latency, short-range link between compatible 100GbE ports, commonly used in data center switch-to-switch or switch-to-server interconnects. The cable is a pre-terminated solution for easy installation and reliable high-speed connectivity.

## Long description

Direct Attach Cable BlueOptics NDAAFF-0002 100GBASE-CR4, 2 m copper twinax is a factory-terminated short-range interconnect designed for 100GbE environments. The 2 m twinax copper cable provides a fixed electrical connection between compatible 100GBASE-CR4 ports, offering low latency and predictable signal performance for data center switch-to-switch or switch-to-server links. As a pre-terminated direct attach cable, it simplifies installation and eliminates the need for separate transceivers and fibre patching for short-reach connections.
Advantages
This 2 m direct attach cable delivers consistent high-speed 100GbE connectivity with lower power consumption compared with optical transceiver plus fibre assemblies in short-reach scenarios. Its pre-terminated design reduces installation time and potential points of failure, while the copper twinax medium provides stable electrical performance and minimal added latency. The cable’s compact form factor and fixed length help maintain tidy rack management and predictable signal path characteristics.
Suitable for
Short-range 100GBASE-CR4 links between data center switches
Direct 100GbE connections from switches to top-of-rack servers with compatible ports
High-density racks where low latency and reduced power are required
Environments preferring pre-terminated copper twinax for predictable performance
Key specifications
Data rate: 100 Gbps over CR4 electrical interface
Media type: copper twinax (direct attach)
Length: 2 metres
Connector configuration: fixed pre-terminated 100G electrical connectors compatible with CR4 ports
Typical use range: short-reach intra-rack and adjacent-rack links
Latency: low electrical latency appropriate for data centre interconnects
How to use
Install the cable by inserting each pre-terminated connector into the corresponding 100GBASE-CR4 port on the network devices until the connector latches. Ensure both equipment ports support 100GBASE-CR4 electrical interfaces and are powered down or follow hot-plug guidance from the device manufacturer. Route the 2 m cable to avoid tight bends and mechanical strain; maintain manufacturer-recommended bend radius for twinax copper to preserve signal integrity. After physical connection, verify link status and correct speed negotiation on the devices' management interfaces.
Usage recommendations
Use this direct attach copper twinax cable for short-distance, high-throughput links where optical transceivers are unnecessary. Confirm port compatibility and firmware support on both ends before deployment, and avoid excessive bending or compression of the cable to maintain performance and longevity.
