Optical parallel interconnection characteristics of 4-channel 2-Gbit/s bit synchronous data transmission module

摘要

A simple 4-channel 2-Gb/s optical parallel interconnection module, allowing a bit synchronous data transmission over a distance of 100 m, has been fabricated. This module employs a lensless optical coupling system between 4-arrayed LD/PD and ribbon fiber, which requires no careful optical axis alignment by using the silicon micromachining technique and an MT (mechanically transferrable) connector. The optical transmitter and receiver are fabricated using the hybrid mounting technique on copper-mount backed polyimide multilayer substrate. This mounting technique can enhance the heat transfer, high-frequency, and skew characteristics. The module can be applicable to intra- and for inter-cabinet interconnections of 2-Gb/s data without any bit synchronizing circuit.
