Product Description


JW3306B High Performance Handheld Optical Fiber Identifier




JW3306B 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 JW3306B 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: 0.25, 0.9, 2.0 and 3.0. The WF3306A optical fiber identifier is powered by a 9V alkaline battery.



·  Easy-to-use with ONE KEY”l operation.

·  Efficiently identifies the traffic direction and frequency tonel (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.
