Hi Ravil
Thanx for your reply
You are right when i reduce system bitrate upto 8Gbit/s timing jitter removes from uplink. But it appears at 13Gbit/s.
I am using wavelength reuse concept and down link wavelength is using in uplink part.
1-The downlink system is good at 13Gbit/s So i can not change the system bitrate to 8Gbit/s and i have to optimize uplink on 13Gbit/s.
2- How can i tackle with timing Jitter that is appeared on uplink???
And Fiber length is not Paying any effect on Timing Jitter. Whether i increases or decreases the length….. Showing same results on 25km and 75km.
