Application Of OTN In The Operating Metropolitan Area Network

With the arrival of the era of business operation, telecom operators provide no longer just such traditional voice service, but the transition for ICT comprehensive service provider. Role change,3G communications and IPTV, the rapid growth of the broadband business, need operators man transmission capacity is more and more strong, way more and more flexible. In this paper based on T1/E1of the first generation of digital transmission network, and based on the SONET/SDH second generation of digital transmission network, and on the basis of illustrating their already no longer can meet the demand of the man. Optical transmission network OTN as a third generation transmission network technology standards, inherited SDH WDM and the double advantage, is large particles broadband business an ideal scheme transmission.OTN papers on the system structure, composition and function of each layer, key technology paper and analysis. In zhenjiang unicom intracity networks nearly four years of the online user quantity, export traffic spikes data as the basis, the expansion of comparing with traditional methods, the author puts forward to OTN technology as operators of expansion plan.In this paper application of man OTN zhenjiang unicom object, the full needs analysis, and the flow analysis and power saving choice made plenty of research, the ring, three counties and the topological structure of the ring choosing the overall design. In OTN equipment selection, fully considered advanced, usability, safety, fault tolerance, can pay sexual factors, for OTN nets yuan chose zte’s corresponding equipment. In the detailed design, this paper gives the OTN and YeWuWang interface definition, each room facilities configuration, relay cable configuration, business wave way configuration, business protection way, etc. The paper also is OTN in zhenjiang unicom in man the actual operation and maintenance are described, for an equipment compatible and uninterrupted flow problems and their solutions are explained. Finally through the scheme design and operation in the OTN technology is the argument of the transmission network operators best solutions.
