Embodiment Construction

[0016] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0017] 1. This method uses a 650nm laser as the indicator light. This kind of laser is cheap, visible, and has good light directionality, and the light spot formed on the reflective screen is small, which can ensure the accuracy.

[0018] 2. This method uses the tight fit process to carry out the assembly process of the adapter and the square metal parts:

[0019] 1) Initial position calibration: In this method, first fix the position of the square metal part 5 and the coaxial center of the down-pressing jig 2 of the hand plate on the lower mold 6, lay it flat, and place a four-sided and square metal part 5 on the square metal part 5. A metal piece parallel to the metal piece 5, paste a small mirror surface on one of the outer surfaces of the metal piece, so that the side with the mirror is in the sam...

Abstract

The invention relates to a fiber adaptor single fiber doubleaction device and the four-sided metalwork assembly technology, which is characterized in that: the process includes: 1. initial position adjusting is that fixing the four-sided metal component on the lower die of the push clamp with the same axle of handle plate press, placing a metal block which has four sides paralleled with the four-sided metal component and one outer surface stuck with a small reflector, adjusting position of the incoming ray, letting the reflecting ray shine on the receiving screen, and marking the position of facular with marker pen; 2. opening red light, covering the fiber adaptor around the push clamp of the handle plate press, letting the ray shine on the 0 degree spectral filter of the adaptor, which has fixing relative position with the 45 degree spectral filter, turning the adaptor, making the ray reflect by 0 degree spectral filter on the facula of the receiving screen which is matched with the position marked by marker, at last pressing the fiber adaptor of the push clamp into the four-sided metal component.

Description

technical field [0001] The invention relates to a single-fiber bidirectional device, in particular to an assembly process of an optical fiber adapter and a square metal part of the single-fiber bidirectional device. Background technique [0002] The product shown is currently an optical communication device widely used in fiber-to-the-home projects. Through it, one optical fiber can be used to transmit two channels of signals, one of which uses 1310nm optical signal transmission, and the other uses 1550nm optical signal transmission. . Among the two signals, one transmits the uplink signal and the other transmits the downlink signal. The working principle of this device is: use a band-pass filter at an angle of 45 degrees to the optical axis of the emitting device, and coat it with a 1310nm or 1550nm high-reflection film to allow only 1310nm or 1550nm light to pass through. If it is a 1310nm optical filter, the optical signal emitted by the 1310nm laser can be coupled to t...
