The debugging method according to the invention is simple and convenient in operation, high in debugging result consistency, low in insertion loss and high in yield, and can be widely applied to the field of optical fiber communication.

Description

Technical field [0001] The invention relates to the field of manufacturing methods for single-mode broadband dual-fiber collimators, in particular to the debugging technology of single-mode broadband installed fiber collimators, and specifically refers to a single-mode broadband dual-fiber collimator debugging system and method. Background technique [0002] At present, the common manufacturing method of single-mode broadband dual-fiber collimator is generally to use the mirror of the corresponding wavelength range to be placed at the image side focus of the lens calculated at a certain wavelength point or at a certain distance for debugging; because of the waveband 1260~1620nm is the common wavelength band of optical communication, so the dual wavelength points of 1310nm and 1550nm are selected for debugging and monitoring to meet this broadband requirement. Use the fusion splicer, cutting knife and wire stripper to connect the single-mode broadband dual-fiber collimator to be d...

Problems solved by technology

There are too many factors that affect the coupling insertion loss in this method. The melting loss of the fusion splicer is too large, the fiber cutting end face is bad, the lens end face is dirty or the lens is eccentric, the adjustment of the one-dimensional adjustment frame is not in place, and the focal length position may affect the coupling insertion loss. , resulting in slow debugging and slow start for new employees
