JW3306B Optical Fiber Identifier is an essential installation and maintenance instrument. By inserting the fiber into its adapter head, it can 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 JW3306A optical fiber identifier also 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 adapter heads available: 0.25, 0.9, 2.0 and 3.0.

The JW3306A optical fiber identifier is powered by a 9V alkaline battery.

Features:
• Easy-to-use with " ONE KEY " operation.
• Efficiently identifies the traffic direction and frequency tone ( 270Hz, 1KHz, 2KHz) with audible warning.
• Displays the core power of the fibers ( -50~ + 0dBm)
• Low bending loss and highly efficient output
• Easy-to-replace adaptors ( 0.25, 0.9, 2.0, 3.0 to match various optical cables)
• Mechanical damp design of adapter heads to ensure the fiber without damage.
• Durable metal housing and quality construction

Applications:
• Maintenance in Telecom
• Maintenance CATV
• Fiber Optic Lab Testing
• Other Fiber Optic Measurements
• To find existing FO cables that active / in use.
