提出了一种基于时域波长交织的新型无源光网络架构,阐述了其基本工作原理,并给出了一种系统实现方案以改善光接入网物理层的安全性,并降低ONU的能耗。基于该架构,针对一个2通道,速率为1.25Gb/s的系统进行了仿真验证。结果表明,该架构在保证安全性和降低能耗的同时,能够满足光接入网的要求,实现20km的无误码传输。
A new passive optical network architecture based on time-domain wavelength interleaving is proposed. Its basic working principle is described. A system implementation solution is proposed to improve the security of the physical layer of the optical access network and reduce the energy consumption of the ONU Consumption Based on this architecture, simulations were performed on a 2-lane, 1.25Gb / s system. The results show that this architecture can meet the requirements of optical access network while ensuring security and reducing energy consumption, and achieve 20km error-free transmission.
