Title:
DIFFERENTIAL TRANSMISSION LINE, OPTICAL TRANSMISSION DEVICE, AND MANUFACTURING METHOD OF DIFFERENTIAL TRANSMISSION LINE
Document Type and Number:
Japanese Patent JP2015198350
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a differential transmission line and an optical transmission device, capable of reducing an amount of crosstalk between differential transmission lines, narrowing an area occupied by the differential transmission lines, acceleration, and high density mounting.SOLUTION: The differential transmission lines are arranged side by side on the same layer above a ground conductor layer. Each of the differential transmission lines is embedded with a first pair of strip conductors composed of a first right side strip conductor and a first left side strip conductor. The differential transmission lines are formed from on the ground conductor layer to above the first pair of strip conductors. The differential transmission lines include a dielectric layer whose top surface is flat. A conductor is not disposed between neighboring two pairs of first strip conductors.
