摘要

文章提出了一种基于可调谐F-P腔滤波器的光分插复用器（OADM）

对它的串扰特性进行了详细的分析与计算

提出了减小串扰的改进措施;实验中

下载波长谱线宽度仅为0.18 nm

插损为4.2 dB

信道隔离度大于26.5 dB

自由光谱范围（FSR）大于33 nm。该OADM具有结构简单、隔离度高、可精密调谐、插损小、成本低和功耗低等特点

可广泛应用于现有的密集波分复用（DWDM）系统。

Abstract

A novel Optical Add/Drop Multiplexer（OADM） based on the tunable F-P cavity filter is presented.Its crosstalk characteristics are analyzed and calculated in detail and measures for improvement proposed.In the experiment

the spectral line width and insertion loss of the downloaded wavelength are only 0.18 nm and 4.2 dB respectively;the channel isolation is greater than 26.5 dB and the Free Spectral Range（FSR） wider than 33 nm.The OADM is characteristic of simple structure

high isolation

precision tuning

small insertion loss

low cost and low power consumption and can be widely used in the existing DWDM systems.
