The SUN-FI316 Optical Fiber Identifier is a handheld device that can identify single-mode optical fibers without damage by detecting optical signals. It displays the core power level and identifies frequency tones without interrupting fiber network services. It comes with interchangeable adapter heads that fit various fiber sizes and allows identification of fibers in both directions.

SUN Telecom’s SUN-FI316 Optical Fiber Identifier is an essential installation and maintenance
instrument.
By inserting the fiber into its adapter head, SUN-FI316 Optical Fiber Identifier 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 SUN-FI316 Optical Fiber
Identifier also allows relative core power display and identification of the 270Hz, 1 kHz and 2 kHz
frequencies. When they are used to detect the frequency, the continuously audible tone is activated.
There are four types of adapter heads available: 0.25mm, 0.9mm, 2.0mm, and 3.0mm.
Applications:
Maintenance in Telecom
Maintenance CATV
Test Lab of optical fibers
Other Fiber Optic Measurements
Features:
Efficiently identifies the traffic direction and frequency tone (270Hz, 1KHz, 2KHz) without any
damage of the fibers
Displays the core power of the fibers (-50~+0dBm)
Low bending loss and highly efficient output
Easy-to-replace adaptors (0.25mm, 0.9mm, 2.0mm, 3.0mm to match various optical cables)
Mechanical damp design of adapter heads to ensure the fiber without damage
