Birefringence Mapping in an Optical Fibre by Using a Polarization-OTDR
نویسنده
چکیده
We propose a new analysis method of the Rayleigh backscattered field for the measurement of the birefringence spatial distribution in a single-mode optical fiber. The technique is based on a Polarization-OTDR set-up using a rotary linear polariser. We demonstrate that the birefringence distribution may be deduced from the measurement of the round-trip Mueller matrices derived from three POTDR traces corresponding to three different angles (0, π/4, π/8 rad) of the polarizer.

Measurement and analysis of polarisation effects in optical fibres with a polarimetric OTDR
where, in electrical measurement, a transmitter sends a pulse along a coaxial cable and a receiver and oscilloscope monitor the echoes returning back to the input. Optical TDR was first demonstrated by Barnoski and Jensen in 1976 in multi mode fibres [17] and over the years, it has proved to be an invaluable diagnostic tool for use in both multi mode and single mode optical fibre systems to mea...

A spectral-hole created by locally pressing a fibre Bragg grating (FBG)s exhibited a wavelength-shift within the FBG bandwidth. A sensitivity of 74.3 pm/(N/mm) was obtained for pressure applied along the slow axis of a high birefringence fibre. ©2006 Optical Society of America OCIS codes: (060.2370) Fiber optics sensors; (060.2420) Fibers, polarization-maintaining

Calibration of Optical Time Domain Reflectometer (OTDR) has a crucial role for the accurate determination of fault locations and the accurate calculation of loss budget of long-haul optical fibre links during installation and repair. A comparison has been made between the Egyptian National Institute for Standards (NIS-Egypt) and the National Metrology institute of South Africa (NMISA-South Afri...

متن کاملFem Analysis of an Ellipltical-core Segmented Cladding Fibre
We analyze an elliptical core segmented cladding fibre using the vector finite element method (FEM) and show that the segmented cladding can effectively control the birefringence of the fibre. The analysis should be useful for fibre-based polarization controlling devices and single-polarization devices.
