Description

technical field [0001] The invention relates to an optical module and belongs to the technical field of optical communication component manufacturing. Background technique [0002] In the field of optical modules, with the development of optical communication technology, especially the greatly improved signal transmission rate, more stringent challenges are posed to the interconnection between circuit boards and semiconductor optical components. Specifically, the current industry will use a single-wavelength 50G, or even a baud rate of about 100G, which is greatly improved compared with the single-wavelength bandwidth rate of the 4X25Gb / S form of the common 100G module. With the increase of the single-wave rate, the signal integrity problem of high-speed signals is also highlighted. The signal integrity problem caused by excessive impedance, poor sealing performance, and poor heat insulation performance has become very serious. Contents of the invention [0003] The purpo...
