10G SFP+ to SFP+ DAC

FIBERLAND’s DAC SFP+ Copper Cables are full-active 11.1Gbps cable assemblies. The cables are compliant with the current SFF-8431, SFF-8432 and SFP+ MSA specifications. They fill the expanding need for cost effective data center interconnects that cannot be served with passive copper or expensive fiber optic solutions. FIBERLAND’s unique low power silicon provides the additional benefit of consuming 50-75% less power than optical interconnects. When systems are optimized to operate with active copper cables, the end-to-end interconnect consumes significantly less power and emits less EMI than passive copper based systems that require the use of EDC hosts.

SFF-8431 requires active SFP+ cable assemblies to meet an output eye mask requirement when a minimal eye is transmitted through the cable assembly. The input eye mask is measured by transmitting a 10.3125 Gbps PRBS 31-1 signal into a module compliance test fixture and measuring the eye pattern through the mated host compliance test fixture. Once the input signal is established, the cable assemblies are measured through the module compliance test fixture. All cable assemblies meet the bit error rate requirement of 1x10-12. This design allows for output de-emphasis and signal amplitude to be adjusted to accomodate customer requirements.
