TWFOI-A visual fault locator Characteristics: Easy-to-use with “ONE KEY” operation Efficiently identifies the traffic direction and frequency tone (270Hz, 1KHz, 2KHz) with audible warning Displays the relative core power More accurate test with Sunshade Easy-to-replace adaptors Durable metal housing and quality construction Lower power indication TWFOI-A visual fault locator Application: Maintenance in Telecom Maintenance CATV Test Lab of Optical Fibers Other Fiber Optic Measurements TWFOI-A visual fault locator Brief Introduction TWFOIA Optical Fiber Identifier can quickly identify the direction of transmitted fiber and display the relative core power without any damages to the bended fiber. When the traffic is present,the intermittently audible tone is activated. The TWFOIA optical fiber identifier also recognize the modulation like,270Hz,1kHz and 2kHz .When they are used to detect the frequency, the continuously audible tone is activated. There are four adapter heads available: Ø0.25, Ø0.9, Ø2.0 and Ø3.0. The JW3306A optical fiber identifier is powered by a 9V alkaline battery .
