[JW3306B optical fiber identifier] Zhengzhou where to sell? Product quality and after-sales what? Tel: 18939564786 Product Overview the: JW3306B Optical Fiber Identifier is a not destroy the fiber, without interrupting the communication under the premise quickly and accurately identify the fiber-optic line, pointed toward optical signal by the optical signal and displays the relative optical power fiber value, and it can identify 270Hz, 1KHz, 2KHz modulation signal, optical fiber chuck with mechanical damping design, to ensure that the wrong fiber damage, fiber optic lines routine maintenance, repair and business with the cutover essential tool , but also has the sound and light alarm and key lock function, to make it easier to use, more comfortable operation. Product features: digital display portable models the relative optical power in the fiber, without interrupting fiber able to identify the direction of the light and the frequency of use "push to talk" mode of operation, simple operation, convenient for bare fiber and a variety of pigtail The adapter head can identify three common signal frequency of 2 kHz, 1 kHz, 270Hz technology indicators: instrument the Model JW3306B wavelength recognition range 800-1700nm identify the type of signal CW, 270HZ ± 5%, 1 kHz ± 5%, 2 kHz ± 5% detection head model? 1mm InGaAs 2pcs adapter type (mm)? 0.25 for bare fiber? 0.9/2.0/3.0 for LED indication about the direction of the pigtail signal relative optical power digital display light signal frequency 270Hz, 1KHz, 2KHz LED indicator Operating Temperature (° C) -10 to +60 Storage Temperature (° C) -25 to +70 9V battery Dimensions (mm) 195x30x27 Weight (g) 235 standard: JW3306B optical fiber identifier 1 user manual 1 warranty card a certificate a 9V battery adapter first four cleaning swabs a desiccant an Oxford cloth soft pack 1 Zhengzhou Hanson Radio and Television Communications Equipment Co., Ltd.
