I census instrument cable for telecommunications engineers and technicians provide the easiest way to troubleshoot fiber optic instrument, clear track and identify targets fiber / cable. A lot of time at this stage because the long-term communications cable, fiber optic cable on the nameplate off, how the cable on the same routes Flanagan could not tell in the end is the target cable, to routine maintenance and cutover diversion with a lot of trouble, often resulting in large communication accidents, early identification cable is to strengthen the middle of the cable core to identify, but the cable construction process in order to prevent lightning current burn room equipment Fiber investigation instrument specifications, so every dish in the middle of a metal reinforced core cable is disconnected, the use of optical fiber sensing principle, as long as the fiber is where we can, together with the supply of fiber optic test instrument investigation when a technician at knocking the target fiber / cable, via sensor technology, without the need to connect the cable to strengthen the core of the issue is easy via fiber Get the audio and video signals. With high sensitivity, anti-electromagnetic interference, easy to operate, for telecommunications operators room building, line transformation, cable cutover, standardized management, resource survey, duty to maintain a very important role in the noisy environment of the target cable performs a voice / video dynamic range of a detector, International Audio - Fiber patent 2, field application and strong, for practical large telecommunications users 3, the cable remote listens mechanical perturbations 4, in a noisy environment by locating an audio or video cable 5, optimizing the dynamic range for testing fiber optic line to troubleshoot instrument prices of different lengths, Xin Hao Yuan (certified), fiber optic instrument investigation by Tianjin Xin Hao Yuan Science and Technology Development Co., Ltd. Tianjin Xin Hao Yuan Science and Technology Development Co., Ltd. (tjaic.gov.cn/shownews.asp?id=5921) is Tianjin, special instrumentation leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness , and satisfy customer needs. Xin Hao Yuan in leadership with the staff warmly welcome all inquiries negotiations to create a better future Xin Hao Yuan.
