Problems solved by technology

[0005] However, the first conventional example described above requires not only a large number of components but also a large number of optical axis adjustment points, which is disadvantageous in size reduction and cost reduction
[0006] On the other hand, the second conventional example considers carrying an end face light-receiving / emitting type optical element, and therefore, it is not suitable for carrying a standard, low-cost PIN-PD (PIN-Photodiode)

Abstract

According to the present invention, there is provided a manufacturing method for an optical module made up of an optical element (1), a protective component (3) for protecting an optical transmission medium (3a) to be optically coupled to the optical element (1) and an electric wiring (3b) formed on the protective component (3) in conjunction with the optical element (1).

Description

technical field [0001] The present invention relates to an optical module, a manufacturing method of the module, a protection assembly, and a protection assembly with electrical wiring, for example, to an optical transmission module and an optical reception module suitable for use in data transmission in next-generation server systems and the like Technology. Background technique [0002] Since data transmission in a server system relies on massively parallel transmission, a large number of optical modules need to be installed in parallel. This requires size reduction and cost reduction for each optical module. [0003] As a first conventional example, Figure 22 A CAN package type optical module for optical communication is shown. Such as Figure 22 As shown, a conventional CAN packaged optical module includes the following main components: an optical element 100 such as a laser diode (LD) or a photodiode (PD), (two) lenses 200, a sleeve 300 for protecting an optical fibe...
