To-type optical element package for high-speed communication

Abstract

A TO-type optical element package for high-speed communication which is used for an optical module for high-speed communication of at least 10 gigabits per sec (Gbps) and enables thermoelectric elements to be embedded in an upper part of a stem. The TO-type optical element package for high-speed communication can transmit high-quality signals in a high-speed operation of the optical element by inserting and fixing an electrode pin (120) in a through-hole formed on a stem base (100), surrounding a lateral surface of the electrode pin (120) protruding to an upper part of the stem base (100), with a metallic instrument (400) having a through-hole so as to enable the impedance of an electrode pin (120) part, surrounded with the stem base (100), to correspond to the impedance of an electrode pin (120) part protruding to the upper part of the stem base (100).
