Optical Time Domain Reflectometer (OTDR) is an intelligent meter of a new generation for the detection of fiber communications systems. With the popularization of optical network construction in cities and countrysides, the measurement of optical network becomes short and disperse; 3302F is specially designed for that kind of application. It’s economic, having outstanding performance. 3302F is manufactured with patience and carefulness, following the national standards to combine the rich experience and modern technology, subject to stringent mechanical, electronic and optical testing and quality assurance; in the other way, the new design makes 3302F smarter. Whether you want to detect link layer in the construction and installation of optical network or proceed efficient maintenance and trouble-shooting, 3302F can be your best assistant.

3223 Power meter and VFL integrated in one unit, this tester allows to perform both optical power/loss measurements and Fiber faults tracing visually.

3213 Series PON Optical Power Meter target at the FTTx application and maintenance. This power meter is able to simultaneously test and estimate the signals of the voice, data and video. It is an essential and ideal tool for the construction and maintenance of the PON projects.

3306B Optical Fiber Identifier can quickly identify the direction of transmitted fiber and display the relative core power without any damages to the bend fiber. When the traffic is present,the intermittently audible tone is activated. The 3306B optical fiber identifier also recognize the modulation 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. The 3306B optical fiber identifier is powered by a 9V alkaline battery .
