Measuring and studying the effective area of single mode fibers by the variable aperture technique
The effective area is an important parameter of single mode fiber. Up to now
its measurement has not been studied and set up in China. In this paper
it is reported that we have first time measured the FFP、NFP and the Effective Area of single mode fibers with difference Refractive Index Profiles by the Variable Aperture Technique. Based on the results
we have proved the relationship between fibers’ effective area and mode field diameter
that is supplied by the ITU T Recommendation. Meanwhile
the Effective Areas have been measured in details for fiber companies’ G.655 fiber products.
