High reliability pre-mold package with optical fiber guide pipe

A pre-mold package with optical fiber guide pipe has been developed to supply the low cost package for the access network systems market. This paper describes the PD module utilizing the premold package which has a very low variation of dark current after the reliability test. It is very close to that of TO-CAN type PD. In this paper, we propose the premold package to meet the market requirements offering low cost and high reliability solution.
