Embodiment Construction
[0047] The present invention will be described below in conjunction with the accompanying drawings.
[0048] The invention relates to a manufacturing process of an all-fiber-optic current transformer, aiming at the manufacturing of a FOCT optical circuit, including a photoelectric optical circuit integration process and a modulation optical circuit integration process.
[0049] The photoelectric optical circuit integration process integrates the photoelectric optical circuit. The integrated photoelectric optical circuit realizes the functions of optical devices such as light sources, beam splitters, and photodetectors in the optical path of traditional processes. However, the design principles and production processes are fundamentally different. The optoelectronic optical circuit integration process applied for adopts the pigtail coupling type process scheme. Photoelectric optical circuit integration process The principle of integrated photoelectric optical circuit 1 is as fo...
