基于RSOA再调制WDM-PON的移动前传调制方式
|
摘要
将波分复用无源光网络(WDM-PON)作为移动前传解决方案,研究了基于RSOA的WDM-PON移动前传网络在下行速率40Gb/s、上行速率10Gb/s时不同调制方式对系统性能的影响。上行信号采用不归零(NRZ)码,下行信号分别采用光双二进制(ODB)、改进型双二进制(MDB)、4阶强度调制(PAM-4)和差分相移键控(DPSK)调制方式。通过建立仿真系统,研究4种下行调制方式时的系统性能,测得了上/下行信号的眼图和Q值。
This paper taking WDM-PON as mobile fronthaul solution, studied the effect of different modulation schemes on the WDM-PON mobile fronthaul network system performance, which is based on the RSOA.The study was conducted at a downlink rate of 40 Gbit/s and an uplink rate of 10 Gbit/s. With uplink signals using no-return-to-zero(NRZ) modulation mode, the downlink signals use optical duobinary(ODB), modified doubinary(MDB),4 order pulse amplitude modulation(PAM-4), differential phase shift keying(DPSK) modulation method respectively. In software, a simulation system is established to study the system performance of four descending modulation methods. The eye digram and Q values of the up/down link signals are detected.
