VFL Visual Fault Locator is the most commonly used, easy to carry and easy to operate. Use a Visual Fault Locator to illuminate the optical fiber connector in the direction of the optical cable, and adjust the button to emit light all the time or pulse light.

Ada: doing fiber optic cable construction will definitely come into contact with such equipment as optical power meter and OTDR (optical time domain reflectometer). Many users do not understand why the optical power meter needs to be used to test the optical loss after testing the OTDR? Does OTDR no

The unit of optical power is dbm. It has its luminous and received optical power in the manual of the fiber optic transceiver or switch. Usually the luminous is less than 0dbm. The minimum optical power that the receiving end can receive is called sensitivity, and the large optical power that can be

The development of optical fiber communication has played an important role in China's economic construction. Optical fiber communication has incomparable advantages: the transmission frequency is wide and the loss is less. The construction of optical fiber communication started in the 1990s and has
