Abstract
Official abstract text for this publication.
An optical module includes a package, a substrate, a lead pin, and a ground pattern. The substrate is accommodated in the package, includes a signal line pattern that transmits an electric signal, extends toward a side wall of the package beyond an end of the signal line pattern, and has a through hole between the end of the signal line pattern and the side wall of the package. The lead pin is inserted into the through hole in the substrate and inputs the electric signal to the end of the signal line pattern. The ground pattern is provided in at least a part of regions surrounding the through hole on the substrate.
First claim
Opening claim text (preview).
What is claimed is: 1 . An optical module comprising: a package; a first substrate that is accommodated in the package, includes a signal line pattern that transmits an electric signal, extends toward a side wall of the package beyond a first end of the signal line pattern, and has a first through hole formed between the first end of the signal line pattern and the side wall of the package; a lead pin that is inserted into the first through hole in the first substrate and inputs the electric signal to the first end of the signal line pattern; and a ground pattern that is provided in at least a part of regions surrounding the first through hole on the first substrate. 2 . The optical module according to claim 1 , wherein the ground pattern is provided in a region, out of the regions surrounding the first through hole on the first substrate, between the lead pin and the side wall of the package. 3 . The optical module according to claim 1 , wherein the ground pattern is provided in a region, out of the regions surrounding the first through hole on the first substrate, between the lead pin and another lead pin that are adjacent to each other. 4 . The optical module according to claim 3 , further comprising: a second substrate that is accommodated in the package, and has a signal electrode electrically connected to a second end opposite to the first end of the signal line pattern and a ground electrode disposed along the signal electrode, wherein the ground pattern extends along the signal line pattern from the region, out of the regions surrounding the first through hole on the first substrate, between the adjacent lead pins, and is electrically connected to the ground electrode of the second substrate. 5 . The optical module according to claim 1 , wherein the first substrate has a second through hole that electrically connects the ground pattern with a ground layer provided inside the first substrate or with a ground layer provided on a surface of the first substrate opposite to a surface on which the ground pattern is provided.
