We have talked about some questions about the optic fiber in last essay, now we can share with you about the other questions if you have the spare time to listen to the fiber optic manufacturer in china. I believe you can learn something about it if you really have got some basic knowledge about it.
 
First, what is the backscatter method?
Answer: backscatter method is a measurement of the length of the fiber attenuation along the way. Fiber optical power the vast majority of the forward spread, but there are a very small part towards the backscattered light emitters. The use of the light-emitting device of the splitter observed backscatter time curve, not only measure access from one end of the fiber length uniformity and attenuation, and can measure the local irregularities, breakpoints, and the joints and connectors caused optical power loss. You can get this information from fiber optic cable supplier.
What’s more, what optical time domain reflect meter (OTDR) test is the principle? What is the function?
Answer: OTDR-based optical backscatter and Fresnel reflection principle of making, using light generated after propagation in the fiber attenuation of the scattered light to obtain information that can be used to measure the fiber attenuation, splice loss, fiber fault location and Learn loss distribution along the length of the fiber, is the cable construction, maintenance and monitoring of essential tools. The main indicator parameters include: dynamic range, sensitivity, resolution, measurement time, and blind and so on.
