GPON简介1.1 GPON技术起源于19

36、95年开始逐渐形成的 ATMPON技术标准，PON 是英文 无源光网络”的缩写。而GPON(Gigabit-Capable PON)最早由FSANd0Pment组织于2002年9月提出，ITU-T在此基础上于2003年3月完成了 ITU-T G984.1和G.984.2的制定，2004年2月和6月完成了 G984.3的标准化。 从而最终形成了 GPON的标准族。 基于GPON技术的设备基本结构与已 有的PON类似，也是由局端的 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），连接前两种设备由单模光纤（SM巾ber）和无 源分光器（Splitter）组成的ODN（光

37、分配网络）以及网管系统组成。1.2 GPON的特点及优势（1）前所未有的高带宽。GPON速率高达2 .5 Gbps,能提供足够大的带宽以 满足未 来网络日益增长的对高带宽的需求，同时非对称特性更能适应宽带数据业务市场。（2） QoS保证的全业务接入。GPON能够同时承载 ATM信元和/或GEM 帧，有很 好的提供服务等级、支持 QoS保证和全业务接入的能力。目前， ATM承载话音、PDH、 Ethernet等多业务的技术已经非常成熟；使用 GEM承载各种用户业务的技术也得到大家的一致认可，已经开始广泛应用和发展。（3） 很好地支持TDM业务。TDM业务映射到GEM帧中，由于GPON TC 帧帧

38、长为125 s,能够直接支持TDM 业务。TDM业务也可映射到 ATM 信元中，也能提供有QoS保证的实时传输。（4）简单、高效的适配封装。采用 GEM对多业务流实现简单、高效的适配 封装。在APON中，所有的多业务流（话音、数据业务流）都必需进行协 议转化，映射到ATM信元中传输。众所周知，5字节的ATM头相对于 48字节的数据来说，会带来超过10%的带宽损失，特别对于长分组的数 据包来说，其打包过程复杂、效率非常低。而在 EPON中，虽然直接承载 以太网帧，实现过程简单，但仅考虑8B/ 10B的线路编码就已经有20%的 带 宽浪费，加上对以太网帧的封装和开销，EPON带宽利用率比 GPON

39、 低30%左右。同时，在传输TDM业务时，需要将其通过协议转化映射到以 太网帧中，目前对此技术还没有规 定统一的标准。GPON的GEM提供了 一种灵活的帧结构封装，支持定长和不定长帧的 封装，对多种业务实现通 用映射，不需要进行协议转换，实现过程简单，开销小，协议封装效率最Innovation, the - s t opay Ie ead ng roe of inova.n i Ie inovainof s ande y.have.a- d a Ie cre of the oveal d 1 opmet of ad teCnolgy inovation Lo in ad dve op te e
