JW3306B Optical Fiber Identifier                                           

Product Description


JW3306B 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.
