随着宽带普及工程的深入开展,ITU-T G.657弯曲损耗不敏感单模光纤已大量使用在与ITU-T G.652D光纤相接的环境中。但目前现有国标的测试方法已不能满足弯曲损耗不敏感单模光纤部分参数的测试。在传送网与接入网技术工作委员会(TC6)线缆工作组近日审查通过的部重点行标“通信用弯曲损耗不敏感单模光纤传输特性和光学特
ITU-T G.657 bending loss insensitive single-mode fiber has been extensively used in the environment connected to ITU-T G.652D fiber with the further development of broadband universal engineering. However, the current national standard test method can not meet the bending loss insensitive single-mode optical fiber part of the parameters of the test. In the transmission network and access network technology Working Committee (TC6) Cable Working Group recently reviewed and approved by the Ministry of key line standard ”bending loss with communication insensitive single-mode optical fiber transmission characteristics and optical special
