摘要

波分复用无源光网络（wavelength-division multiplexed passive optical network，WDM-PON）中，操作管理和维护数据路径与用户数据路径在传输汇聚层是彼此独立的。操作管理和维护数据可以通过透传和码传两种方式进行发送。其中，透传方式由于无需额外的转码器件以及具有低时延等特性被广泛应用于各种行业网络。不同于现有的透传模式，即基带再调制和射频通道，提出了一种新型的基于差分相位再调制与时延干涉检测的辅助管理和控制通道实现方法。所提方法的辅助管理和控制信号以相位参数再调制于用户信号之上，而用户信号采用传统强度调制，因此辅助管理和控制信号的再调制过程将不会对用户信号质量产生影响。相对地，基带再调制和射频通道都会对用户信号造成扰动，这在抖动要求较高的行业网内是不允许的。所提方法被认为是波分复用无源光网络中一种有效的辅助管理和控制通道的实现方法。

Abstract

In WDM-PON

the OAM data path and user data path were independent in the TC layer.The OAM data could be transmitted either transparently or by codec.Specifically

the transparent mode was preferred by the industry network due to the free of codec and low latency.Different from the existing transparent modes

such as base-band re-modulation and RF band

a novel method for the realization of auxiliary management and control channel was proposed

which was based on the DBPSK re-modulation and delay interferometer detection.Since the OAM data was re-modulated on the phase of user data

which was modulated intensively

it would not take any impact on the quality of user data.But

in both base-band re-modulation and RF band methods

the re-modulation of OAM data would introduce interference to the user data

which was not allowed in the demanding industry network.The proposed method is thought promising as one of the solutions for auxiliary management and control channel in WDM-PON.
