Technical index of PLC optical splitter

- Mar 28, 2019-

In system applications, the light ratio is indeed based on the amount of light power required for the actual system light nodes, determining the appropriate light ratio (except for the average distribution), and the light splitter's dimming ratio is related to the wavelength of the transmitted light, such as a light division in the transmission of 1.31 microns of light at the two outputs of the light ratio of 50:50 When transferring 1.5μm light, it becomes 70:30 (this occurs because the optical splitter has a certain amount of bandwidth, that is, the frequency band width of the optical signal transmitted when the light ratio is basically constant). So be sure to indicate the wavelength when ordering the optical splitter.
