Description
FF-3306B 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 traffice is present,the intermittently audible tone is activated.
The FF-3306B optical fiber identifier alsor recogize the modnulation 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.
Features
– 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
