摘要
在全数字网络条件下,利用全光网络进行IPQAM插播成本较高,而利用射频进行插播之后,再用1 550直调发射机传输不失为一种较好的解决方案。针对直调1 550传输系统,在不同距离、不同激光器驱动电平条件下进行实际测试,并得出一些分析结论,供同行参考。
The cost of all-optical network with IPQAM inter-cut is very high,and using the 1 550 nm directly modulated transmitter with radio frequency inter-cut is a better transfer solution.This article is based on the actual test of 1 550 nm directly modulated transmission system at different distances,different laser drive levels.There are some conclusions for your reference.
