TDM-PON上行信号光功率均衡器的锁模特性
光通信 光功率均衡 光注入锁定 法布里-珀罗激光器 分布反馈半导体激光器
2013/12/2
为了减小时分复用无源光网络（TDM-PON）上行信号光波长的飘移，基于TDM-PON上行信号光功率均衡器架构，采用单模激光注入锁定光网络单元（ONU）法布里-珀罗（F-P）激光器（LD）方法，研究了F-P LD输出光波长的锁模特性，包括锁模的范围、驱动电流对锁模特性的影响、锁模前后温度变化引起F-P LD光波长变化情况等。结果表明，当驱动电流为9mA时，F-P LD可被锁模的波长范围为0.38nm...
Over-Sampling based Burst-mode CDR Technology for High-speed TDM-PON Systems
Networks Optical communications
2011/5/22
We review recent progress of a over-sampling based burst-mode CDR as the key PMD device for supporting next-generation, 10Gbps capable TDM-PON systems. For the essence of circuit design, its burst-mod...
Future bandwidth demand favors TDM PON, not WDM PON
Future bandwidth demand favors TDM PON WDM PON
2011/5/18
Claims to the contrary notwithstanding, quantitative trends indicate that TDM PON bandwidth supply is growing faster than subscriber bandwidth demand, and TDM PON will deliver future ultra-high speed ...
Reconfigurable WDM/TDM-PON ring-architecture by using all-optical wavelength converter and injection-locked FP-LD
Fiber optics communications
2010/6/10
We propose and demonstrate a novel ring-based WDM/TDM-PON architecture which can flexibly concentrate subscribers in response to the demand. A wavelength converter and an injection-locked Fabry-Perot ...

In this paper we propose a novel architecture and MAC protocol for a scalable, cost effective WDM /TDM PON providing fully flexible dynamic bandwidth allocation for upstream and downstream data transm...
A Novel Hybrid WDM/TDM-PON using Downlink DPSK and Uplink Remodulated OOK Signals Based on a Shared DI
Hybrid WDM/TDM-PON Downlink DPSK Uplink Remodulated OOK Signals Based
2009/7/16
We propose a novel hybrid WDM/TDM-PON using downlink DPSK and uplink remodulated OOK signals based on a single shared delay interferometer (DI) at remote node. Experiments of 10-Gb/s downstream and 1....
