TO-CAN PACKAGE FOR 10GBPS OPTICAL MODULE

摘要

PURPOSE: A TO-CAN package for use in 10 giga bps optical module is provided to improve the reflection loss to 17db - 37db at a range from 1GHz - 10GHz and to improve the transmittance to -0.03dB - (-0.3dB). CONSTITUTION: A TO-CAN package for use in 10 giga bps optical module includes a stem(10), a lead(20) and an RF feed line. The stem(10) receives an optical device and the lead(20) connects the optical device through the opening formed on the stem(10). The lead(20) placed inside of the TO-CAN package(100) is coated with a first insulating layer form the opening of the stem(10) to a predetermined length. And, the RF feed line is formed by the lead(20) which is placed outside of the TO-CAN package(100) encompassed with a third insulating layer.
