Description

technical field [0001] The invention belongs to the technical field of optical communication devices, and relates to an optical power controller, in particular to a miniaturized optical power controller with SFP (Small Form-factor Pluggable) small-size pluggable package. Background technique [0002] Optical power controllers are widely used in various optical fiber communication systems, CATV networks, optical fiber sensors, and measuring instruments to regulate and stabilize optical power. With the application of wavelength division multiplexing technology in optical fiber communication system more and more widely, the optical power management of each wavelength also uses more and more optical power controllers.

AI Technical Summary

Problems solved by technology

[0007] Generally, on the control circuit board in the traditional optical power controller, the optical attenuator and the optical power monitor are arranged in parallel. The separation distance is usually large, which also makes the lateral size of the optical power controller relatively large

[0008] At the same time, in the traditional optical power controller, the optical fiber is coiled and arranged in the entire three-dimensional space between the top plane of the electronic device on the control circuit board and the housing, which makes the size of the optical power controller in the vertical direction perpendicular to the lateral direction relatively large. bigger

[0009] On the other hand, the traditional optical power controller usually adopts multi-channel integration. This kind of optical power controller is often bulky, and due to the increase of built-in components and the bending optical loss of the optical fiber, the process arrangement of the optical fiber in the free space is complicated. It also caused problems such as large volume of traditional optical power controllers, difficult production and assembly, poor working stability, and inconvenient use.
