Synchronization Network Design Of A Communication Company Based On DWDM

Synchronization network and telecommunications management network, thesignaling network, the three support network of the telecommunications network,is the foundation of the normal operation of the modern communication network.Digital synchronous network can be accurately synchronization information fromthe reference clock is passed to each node of the synchronous network,regulatenetwork clock, to keep pace to meet the telecommunications network to transferbusiness information transmission and exchange performance requirements, is animportant means to ensure that the key aspects of the network timingperformance, but also to protect the quality of a variety of business network run,has a pivotal position in the telecommunications network.Thus, to solve theproblems of synchronization network, not only related to the stable operation ofthe synchronization network, but also can improve the quality of the entirecommunication network.Unstable device itself causes and timing signal transmission link, so thatthe synchronization network often is on hold or fault condition can not be normaland effective working, the output timing signal instability or degradation,resulting in the synchronization network did not play its due role. To this end theneed for clock synchronization network transmission link re-select, and clocksynchronization network planning.This paper start from the basics of the synchronization network, the briefbuilding integrated timing and synchronization to discuss the clock signal chainto pass, focused on dense wavelength division multiplexing technology and howthe clock passed through the dense wavelength division multiplexingsystem.Detailed synchronization network design requires knowledge, includingthe the timing allocation between the timing distribution and Bureau Council,synchronization network structure. Passed through the dense wavelength division multiplexing system clock signal synchronization network is designed based on.Finally, the synchronization network design testing, the results can meet thestandard requirements of the International Telecommunication Union, a goodsolution to the synchronization problems plagued the development of thetelecommunications industry.
