GAO820 Optical Fiber Identifier uses the technique of macro-bending, which is safe and credible. And it is not necessary to interrupt the operation and cut the fiber to identify the transmission directions. The check and measurement of current signal will not affect the normal transmission signal because of the low loss of this method and it can therefore test the transmission speed under the comparison light. It provides 5 grades of indications for the identified transmission signal and the optical signal. It is very useful to the engineer and technical persons to determine the proper core line.
