基于PON的ODN组网模式的探讨

Exploration on ODN networking mode based on PON

ODN是基于PON技术的光纤接入网中从OLT到ONU之间的部分,属于接入光缆网的一部分,为OLT和ONU之间的光信号提供物理传输通道。在不同环境下选择不同的ODN组网模式,对技术的实施、后期的维护管理和投资成本的降低都具有重要意义。文章针对已有的ODN规划原则,提出自己的看法,给出高层住宅、别墅和聚类市场三种典型环境下ODN的组网模式。

ODN is the part from OLT to ONU in the optical fiber access network which is based on PON technology and belongs to the acce cable network, h provides physical transmission channel for the optical signal between OLT and ONU. Choosing different ODN networking model in different environment is of great importance for the technology implementation, later maintenance management and investment cost reduction. Aiming at the existing ODN planning principles, this paper proposes the ODN networking under three typical environments, namely, high-level residence, villa and clustering market.
