Increasing mobile traffic and smart devices require continuous expansion of optical access network capacity and easy optical connectivity for residential, business, and mobile services. A high-speed TDM-PON system with high power budget is an attractive solution to accommodate explosive mobile traffic since multiple remote nodes with simple optical power splitters could easily provide optical connections anywhere in an optical distributed network. Thus, both high speed per wavelength and high-power budget are desirable in the TDM-PON system. We demonstrate a TDM-PON system with 50 Gb/s/λ with PAM4 and 35-dB power budget in the entire O-band by simply operating a booster SOA in the saturation region. In addition, a dynamic range of 50 Gb/s PAM4 receiver higher than 15 dB is demonstrated to support loud-soft ratio. We also successfully demonstrate error-free transmission of 50 Gb/s TDM-PON system by utilizing an OLT line-card and an ONU board.

具有50 Gb / s PAM4和饱和SOA的高功率预算TDM-PON系统的演示

越来越多的移动业务和智能设备需要不断扩展光接入网络的容量，并为住宅，企业和移动服务提供简便的光连接。具有高功率预算的高速TDM-PON系统是容纳爆炸性移动流量的有吸引力的解决方案，因为具有简单光功率分配器的多个远程节点可以轻松地在光分布式网络中的任何位置提供光连接。因此，在TDM-PON系统中，每波长的高速和高功率预算都是期望的。通过在饱和区域内简单地运行升压SOA，我们演示了具有50 Gb / s /λ的PDM4和35 dB功率预算的TDM-PON系统，在整个O波段中。此外，还证明了高于15 dB的50 Gb / s PAM4接收器的动态范围可支持大声柔比。
