星枫 instruments, optical power meter [Model], PM is provided by 星枫 instruments. We are Nanchang Xing Feng Instrument Co., Ltd. (www.xingfengyiqi.com) located: Nanchang, Jiangxi professional: rangefinder, coating thickness gauge, ultrasonic thickness gauge, hardness tester, vibrometer EP300 EPON Optical Power Meter = Installation, commissioning and maintenance of FTTX applicable to business. By using the measurement methods that can simultaneously measure all PON signals, measurable 1310nm burst signal, using TOOLBOX software for data processing. Instrument internal mass storage unit allows users to store up to 1800 test results, and handheld optical power meter can be connected via the USB interface and PC management software, so that the test results are effectively managed. Can be used as an ordinary power meter. EP300 is equipped with a pass / warning / fail LED indicators set by the user to set a threshold optical power meter 12, when the test instrument automatically based on thresholds, given the measured power state. EP300 is your best choice for the development and maintenance of FTTx business. It can simultaneously test the value of the optical power down the line EPON system. And the use of LED indicates pass / fail, so that testing becomes simple, even a beginner can easily grasp. OVA-02 fiber and a variable attenuator is provided to maintain a certain amount of attenuation to the handheld instrument optical fiber strength for the single mode fiber. Its compact, stable performance and can withstand shock and vibration. And it is a two-way attenuation design ideas to make it easy to use, very suitable for field construction. In use, the optical power meter model, OVA-02 with the light source and the optical power meter needs to be used in conjunction. The main features of a single rotating disc operation, simple and fast two-way attenuation, applicability double scale indication, more in line with the physical characteristics of optical fiber machining, compact, stable performance passive design, independent of temperature and humidity affect large attenuation range of 0 ~ 60dB
