The directional coupler factory is one of the important devices of optical system, and it is also one of the optical passive devices. So how can we judge a directional coupler factory? Judging the quality of directional coupler factory from the following aspects.
1. Appearance of directional coupler factory: Generally speaking, when detecting the directional coupler factory, the first thing to look at is the appearance. If the appearance is not up to standard, it proves that the directional coupler factory is unqualified. The general appearance of the directional coupler factory depends on its exterior frame and whether the tail sleeve is qualified. If it is, it proves that the connector is good. If it is not, it proves that the connector is unqualified.
2. Size: No matter what size is important, the directional coupler factory is the same. directional coupler factory is generally composed of external frame, internal frame, tail sleeve, spring, brake, insert, etc. If the size of these devices is qualified, the assembly into a connector is generally good; if the size of these devices is unqualified, the assembly into a connector is also bad. Because the size is not qualified, the assembled connector will have no flexibility and no elasticity, and the connection with the flange is either not inserted or very loose, resulting in unusable, so the size can also judge the directional coupler factory.
3. Performance: The general performance of the directional coupler factory includes: whether there is flexibility, the length of the insert, the protruding length of the insert, whether the insert has chamfer, etc
From these aspects, you can also judge the directional coupler factory. If there is no flexibility, it will affect the use of the directional Coupler Factory. If the plunger length is different, it will affect the docking of two end faces. The normal use of the directional coupler factory will be affected.
The above judgment of the directional coupler factory is based on my personal opinion, and I hope it will be helpful to you when detecting connectors.
