Fast Identification: This fiber optic reader features rapid identification, accurately determining the direction of the transmitting fiber and displaying its relative core power without causing any damage to the fiber or interfering with the network. Three Signal Recognition Capability:This advanced fiber optic reader can recognize three commonly used signal frequencies: 2kHz, 1kHz, and 270Hz. A beep will sound upon frequency recognition. Micro-Bend Testing Technology: This fiber optic reader employs micro-bend testing technology for precise fiber orientation identification. Left and right indicator lights on the device will indicate the signal direction when a signal is present. If the left indicator light is on, it means the light source is shining from right to left. Ergonomic Design:Simply hold the device and press the trigger switch on the back with your index finger. The test will start automatically after the fiber optic cable is clamped. Pressing down securely clamps the fiber optic cable for stable testing. Service: If you have any questions, please feel free to contact us and we will reply within 24 hours!
