工程中光纤故障的分析与处理（Analysis and treatment of optical fiber fault in Engineering）

工程中光纤故障的分析与处理（Analysis and treatment of optical fiber fault in Engineering） Analysis and processing of.Txt optical fiber fault engineering in my life with A are B, your life is B S. Failure is not terrible, the key is not the mother of success. The students now not too much quality! Come copy feather, actually by shear! Free to study Feng Shui, after the death of a tomb is made up of living cant afford to buy a house. ]998 in December The month Designing Techniques of Posts and Telecommunications I). S:grlxng Z, a pan! 21 (a, Ze, ofPosrsandl cleeom; nunieations I E.1998 No.12 Design, construction and maintenance. Analysis and treatment of fiber failure in Engineering Wang Lixuan Peng Yungui Abstract: This paper introduces the fault characteristics of optical fiber attenuation, engineering analysis and optical fiber Treatment, and the use of optical time domain reflectometer (fDR) () test of fiber failure reasons. Keywords: optical fiber fault attenuation of fiber optical fiber transmission system of OTDR ((FL)) R) Introduction Optical fiber communication with the characteristics of large capacity, anti-interference and confidentiality is large The field of communication with all walks of life in the factory, the application of the telecommunications sector J is more widely in order to ensure safe operation of the cable line, fast quasi It is particularly important to accurately rule out cable fault, the multiple benefit Sichuan (OTDR) (TDR) of the fault point in optical fiber test As for narrative divine. A fiber optic attenuation characteristics According to the G.6 against the proposal. At the wavelength of 1310nnl is zero Dispersion wavelength, applied to 1 (T) m Liu), the optimal wavelength region Single mode fiber is called 3L (]) single mode fiber nnl performance, i.e. (in.652 optical fiber, this fiber can also be applied to the L of gansu. M, and the wavelength region Domain. But the wavelength of the fiber dispersion are not optimized. The day before, China
