SFP+ Direct Attach Copper Cables (DAC)

R&M has introduced a new line of small-form high speed copper assemblies. Data centres increasingly need higher speeds, design flexibility and a cost-effective migration path. A new family of Small form-factor pluggable plus transceiver (SFP+) Direct Attach Copper Cables (DAC), also known as Twinax cables, has been designed to meet these requirements.

SFP+ direct attach is the optimum choice for highly cost-effective networking connectivity within a single rack and between adjacent racks. The cables meet application requirements for a high density cabling interconnect system capable of 10G per channel transmission rates and are ideal for point-to-point Top of Rack (ToR) applications.

The full portfolio includes eight cable lengths, from half a meter to seven meters. SFP+ assemblies are offered in different wire gauges depending on length.

The cables have been designed with practical installation and network management in mind: they can be removed and replaced without powering off the switch or server. A programmed EEPROM signature allows the host to differentiate between a copper cable assembly and a fibre optic module and provides length and serial number data for traceability, which can lead to considerable time and cost savings when patching and re-patching systems.

All cables are fully compatible with the SFP Multi-Source Agreement. R&M SFP+ DAC assemblies are compliant to all equipment with MSA compliant ports according to SFF-8431, SFF-8432, SFF-8472, SFF-8083.
