摘要

提出了在千兆带内波分复用(WDM)标准光网中采用波分复用技术对现有无源光网络(PON)进行升级的新方法。其目的是在保持用户带宽的同时，增加由单根光纤馈送的光分配网络(odn)的数量。在这种方法中，使用1480到1500nm的标准DS PON频谱，将四个下游(DS)波长信号从光纤线路终端(OLT)传输到四个不同的odn。来自四个不同odn的上游(US)信号也在标准化的US PON频谱范围从1270到1330 nm内进行波长复用。为了证明该提案的可行性，在一个服务32个ont的20公里PON中提出了概念验证。

Passive optical network upgrading by using In-band WDM overlay

This paper presents a new approach to upgrade the current passive optical network (PON) by using wavelength division multiplexing (WDM) in the standardized optical grid of gigabit PON (In-band WDM PON overlay). The aim is to increase the number of optical distribution networks (ODNs) fed by a single fiber while preserving the users bandwidth. In this approach four downstream (DS) wavelengths signals are transmitted from an optical line terminal (OLT) to four different ODNs using the standard DS PON spectrum ranging from 1480 to 1500 nm. The upstream (US) signals from the four different ODNs are also wavelength multiplexed within the standardized US PON spectrum ranging from 1270 to 1330 nm. Proofs of concept are presented in a 20 km PON serving 32 ONTs in order to demonstrate the feasibility of this proposal.
