Design And Implementation Of Data Acquisition And Analyse System Of 10G OTN Signal

Driven by the power of the information age,global data services expand quickly and application requirements continue to improve.The development of optical fiber communication technology is changing with each passing day.Among them,OTN technology,by virtue of its large capacity transmission channel,transparent transmission and flexibility based on wavelength scheduling and other advantages,becomes gradually the first choice for optical transmission network.With the phase shift modulation and other phase modulation in the transmission system applications,optical signal rate and transmission quality continues to increase,now reach 100 Gbps or even higher.Related equipment is also gradually commercial.But,in long distance transmission system,especially the international sea cable,optical signal rate is still 10Gbps-based.Facing of many types of signals and the situation of the increasingly complex format,developing for a single signal acquisition and analysis of detection equipment from the economic,time and efficiency considerations is obviously unreasonable.The main content of this paper is on the basis of further study of the optical signal access processing and ultra-high-speed data acquisition and analysis,Designing and achieving of a 10 Gbps rate and a variety of specifications OTN signal data reception function of the new optical signal acquisition and analysis system.First of all,the paper described the background,research object and system characteristics.Secondly,the paper introduced the related concept principle of light modulation and elabora ted in detail hardware and software architecture,design principles and workflow of the system,at the same time,analyzed focus on the key technology used in system design and implementation process and frame synchronization recognition algorithm for synchronous word.At last,the paper introduced the system of the indicators and tested by field experiment.The experimental results further verify the stability and reliability of the system hardware and software.
