Direct Attach & Active Optical Cables

Newton Optics Direct Attach Copper (DAC) cable assemblies offer customers a high performance, cost effective I/O solutions for 10G 25G 40G and 100G Ethernet and  Fibre Channel applications.

DAC Cables offer the lowest cost connectivity as well as a high port density and low power requirement. For short distances DAC cables offer a lower cost alternative to SFP+ Transceivers and fibre patch cables.

There are 2 versions of Direct Attach Copper Cable; passive and active. Passive DAC Cables enable connection up to 12m. Active DAC cables have an increased distance (to 15m) and also have a reduced size cable diameter. Note – Some equipment brand will only accept active DAC cables.

Each DAC cable is programmed prior to dispatch with correct code to ensure it is compatible with the brand of equipment. All Newton Optics DAC are fully tested for compatibility prior to dispatch and are MSA (Multi Source Agreement) compliant.


Active Optical Cables offfer a cost-effective solution consisting of fixed fiber optic transeivers on a fiber cable for short reach connections between 1m and 50m. AOCs are a plug and play assembly, reducing the complexity of a standard fiber install. In addition, AOCs single 30mm cable diameter reduces the cable pile up in a data center cable trays over a standard duplex fiber cable deployment.


Multi-vendor Codeable Low Cost 10G, 25G, 40G, 100G.
