ST820 Optical Fiber Identifier adopts the technology of Marco-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 measure of current signal will not affect the normal transmission signal because the low loss and it can test the transmission speed under the comparison light. It has 5 grades indication for the identified transmission signal and optical signal. It is very useful to the engineer and technical persons to choose the proper core line.
