摘要

对单模光纤宏弯损耗进行了理论分析与实验测量

选取D.Marcuse、H.Renner和L.Faustini的理论公式模拟分析了康宁公司SMF28单模光纤的宏弯损耗

并与测量结果进行了对比。结果表明:根据D.Marcuse公式模拟的结果无法预测SMF28光纤宏弯损耗随弯曲半径变化而振荡的趋势

H.Renner的公式能够预测这种趋势

但模拟结果与测量结果差别较大

最大相对误差为57.8%

L.Faustini的公式也能模拟该趋势

且模拟结果与测量结果差别较小

最大相对误差仅为19.6%

是一种较为准确的计算带涂覆层单模光纤宏弯损耗的理论公式。

Abstract

Macrobending loss of single-mode fibers is analyzed theoretically and measured experimentally in the paper.Simulations of macrobending loss for Corning SMF28single-mode optical fiber are conducted based on the formulas proposed by D.Marcuse

H.Renner and L.Faustini

respectively.The measurement and simulation results are compared.The results show that the simulation results based on D.Marcuse’s equation cannot predict the macrobending loss oscillation phenomenon

while the simulation results based on H.Renner’s can predict this phenomenon with largest relative error of 57.8% between simulation and experimental results.Meanwhile

the simulation results based on L.Faustini’s formula can predict this phenomenon with largest relative error of only 19.6%.Therefore

the equation presented by L.Faustini can be considered as an accurate formula to calculate macrobending loss of coated single-mode fibers.
