Description
技术领域technical field
本发明涉及无源光网络传输技术领域,具体涉及一种GPON拉远系统、管理方法及存储介质。The invention relates to the technical field of passive optical network transmission, in particular to a GPON remote system, a management method and a storage medium.
背景技术Background technique
GPON(Gigabit-Capable PON)技术是基于ITU-TG.984.x标准的最新一代宽带无源光综合接入标准,具有高带宽,高效率,大覆盖范围,用户接口丰富等众多优点,被大多数运营商视为实现接入网业务宽带化,综合化改造的理想技术。基于GPON技术的设备基本结构由局端的OLT(光线路终端),用户端的ONT/ONU(光网络终端或称作光网络单元),单模光纤(SM fiber)和无源分光器(Splitter)组成的ODN(光分配网络)以及网管系统组成。目前GPON标准定义支持最大逻辑距离为:60km,支持最大物理距离为:20km,支持最大距离差为:20km,分光比一般为1:64。GPON (Gigabit-Capable PON) technology is the latest generation broadband passive optical integrated access standard based on the ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, and rich user interfaces. Most operators regard it as an ideal technology to achieve broadband and comprehensive transformation of access network services. The basic structure of equipment based on GPON technology consists of OLT (Optical Line Terminal) at the central office, ONT/ONU (Optical Network Terminal or Optical Network Unit) at the user end, single-mode fiber (SM fiber) and passive optical splitter (Splitter) ODN (Optical Distribution Network) and network management system. The current GPON standard definition supports a maximum logical distance of 60km, a maximum physical distance of 20km, a maximum distance difference of 20km, and a splitting ratio of generally 1:64.
在FTTH建设过程中发现,光纤资源是制约FTTH建设的一大关键因素,现有光纤资源有限,光缆资源非常紧缺。同时由于分光衰耗的原因,1:64分光时只能覆盖5km范围,部分地区无法实现业务的覆盖。为了解决此类FTTH光缆资源紧缺和覆盖距离的问题,一般会使用PON光纤聚合拉远设备。In the process of FTTH construction, it is found that optical fiber resources are a key factor restricting FTTH construction. Existing optical fiber resources are limited, and optical cable resources are very scarce. At the same time, due to the attenuation of the light split, the 1:64 light split can only cover a range of 5km, and some areas cannot achieve service coverage. In order to solve the shortage of such FTTH optical cable resources and the coverage distance, PON optical fiber aggregation and remote equipment are generally used.
工作原理如下:在拉远设备中实现4/8路OLT侧GPON业务聚合拉远,OLT侧4/8路GPON接口与局端设备4/8路GPON接口相连,实现OLT侧PON信号的OTU信号转换;远端设备4/8路PON接口与分光器连接,实现局端4/8路GPON信号到远端OTU信号的转换。所有PON接口均相互独立,互不干扰。GPON到OTN的复用过程如下图所示:The working principle is as follows: In the remote equipment, the 4/8 GPON services on the OLT side are aggregated and pulled remotely, and the 4/8 GPON interfaces on the OLT side are connected to the 4/8 GPON interfaces of the central office equipment to realize the OTU signal of the PON signal on the OLT side Conversion; the 4/8-way PON interface of the remote device is connected to the optical splitter to realize the conversion of the 4/8-way GPON signal at the local end to the remote OTU signal. All PON interfaces are independent of each other and do not interfere with each other. The multiplexing process from GPON to OTN is shown in the following figure:
在目前的基于OTN的PON拉远设备中,PON信号被透明传输,在局端拉远设备和远端拉远设备的PON接口中都存在光信号的3R(Re-amplifying,Re-shaping,Re-timing)功能,所以当在整个链路的任何节点出现了光节点故障。OLT设备无法进行有效判断并上报,整个系统的可维护性降低。In the current OTN-based PON remote equipment, PON signals are transparently transmitted, and there are 3R (Re-amplifying, Re-shaping, Re -timing) function, so when any node in the entire link has an optical node failure. The OLT equipment cannot effectively judge and report, and the maintainability of the entire system is reduced.
