wavelength loss

However, in previously reported work with these holographic devices the diffraction efficiency and wavelength selectivity were not so satisfactory, which affected the insertion loss and channel spacing of the device respectively.

但是目前已报导的工作中还存在着衍射效率不高、选择性差等问题，它们分别影响着器件的插入损耗和通道间隔。

One efficient way for reducing polarization dependent loss is using polarization scrambler. Scrambling speed, scrambling uniformity, insertion loss, operating wavelength and the volume are main key indications for a polarization scrambler.

抑制偏振相关损耗的一个有效方法就是使用偏振扰偏器，偏振扰偏器的主要性能指标有：扰偏速率、扰偏均匀性、插入损耗、工作波长及体积等。

关于干涉条纹的级次，兼论“半波损失”

As having advantages such as littler inserting loss, better wavelength selection and absolute coding, FBG has bright prospects of applications in fiber communication and sensing.

由于它具有插入损耗小、波长选择性好及传感信息对波长绝对编码等优良特性，因而在光纤通信及传感领域有着广阔的应用前景。

Further, 1.3-μ m-wavelength LDs have lower loss and negligible dispersion for standard silica fibers.

另外在标准矽光纤内, 1.3微米波长有低损失与可忽略色散特点.
