Abstract

A protocol-free parallel optical interconnecting module is introduced as a solution to solve memory test system transmission bottlenecks. The optical transmission system flexibly suited for a memory test system is reviewed and discussed. A parallel optical module capable of transmitting from dc to 34.1Gb/s (4.267 Gb/s × 8 ch) has been developed. A data transmission throughput density per unit volume of 19 Gb/s/cm3 is achieved. A random jitter of less than 3-ps root-mean-square is also achieved. Furthermore, high-density optical connector,high-density optical fiber cable, fiber guides, and cable management/reinforcement members suited for mechanical requirements of the memory test system have been developed.
