High-density parallel optical interconnection for 10Tbps interconnection in high-speed memory test systems

High-density parallel optical interconnection is introduced as a solution to solve transmission bottlenecks in memory test system. A protocol-free parallel optical module capable of transmitting from DC to 34.1 Gbps (4.267 Gbps × 8 ch) has been developed. Data transmission throughput density per unit volume of 19 Gbps/cc and random jitter of less than 3ps rms are achieved. And also, we will describe the manufacturing process, the module testing, and self-diagnosis for optical transmission system. Furthermore, high-density optical connector and high-density optical fiber cable suited for mechanical requirements of Memory Test System have been developed.
