Fiber Splitter Isolation

Isolation refers to the isolation ability of a certain optical path of a fiber optic splitter to optical signals in other optical paths. Among the above indicators, the isolation degree is more significant for the fiber splitter. In practical system applications, devices with isolation degree above 40dB are often required, otherwise the performance of the entire system will be affected. In addition, the stability of the fiber optic splitter is also an important indicator. The so-called stability refers to that when the external temperature changes and the working state of other devices changes, the splitting ratio and other performance indicators of the fiber optic splitter should remain basically unchanged. In fact, the stability of the optical fiber splitter depends entirely on the technical level of the manufacturer, and the quality of the products of different manufacturers varies greatly. In practical applications, I have indeed encountered many low-quality optical fiber splitters, not only the performance indicators deteriorate rapidly, but also the damage rate is quite high. The price, the price of the optical branch with low technology level is definitely low.
