Fiber Identifier TW3306

Optical Fiber Identifier TW3306B

It is an essential installation and maintenance instrument. By inserting the fiber into its adapter head,

itcan identify SM optical fibers without any damage by detecting the optical signals being transmitted

through them so as to avoid the opening of the fiber at the splice point for identification and thus

avoids the interruption of the service. In the presence of traffic, the intermittently audible tone is

activated. The TW 3306Aoptical fiber identifieralso allows relative core power display and

identification of the 270Hz,1kHz and 2kHz frequencies. When they are used to detect the frequency,

the continuously audible tone is activated.There are four types of adapter heads available: Ø0.25,

Ø0.9, Ø2.0 and Ø3.0. TheTW3306A optical fiber identifieris powered by a 9V alkaline battery.



1) Efficiently identifies the traffic direction and frequency tone (270Hz, 1KHz, 2KHz) without any damage of the fibers.

2) Displays the core power of the fibers (-50~+0dBm)

3) Low bending loss and highly efficient output

4) Easy-to-replace adaptors (Ø0.25, Ø0.9, Ø2.0, Ø3.0 to match various optical cables)

5) Machanical damp design of adapter heads to ensure the fiber without damage.

6)“ONE KEY” operation design, easy-to-use.
