Digital Video, and FICON. It alsooffers highly efficient and flexiblesub-rate convergence of services,including 4×155/622Mbs, 2×GE, 4×2.5Gbs and 8×Any, incorporatingthe ability to realize multiple servicehybrid multiplexing.● Offering a flexible industrial-leadingprotection solution, consisting of sixprotection modes for optical layerand service layer.● Flexible networking modes. With aROADM, carriers can implementa variety of network topologiese.g. multi-ring interconnect, mesh,chain, star, cross, tangent ring,intersectant ring, which allowscarriers to develop new applicationor change service and trafficpatterns in metro networks.ZXMP M600 metro CWDM systemDue to low cost, large capacity,service transparence and scalability,the ZXMP M600 metro CWDMequipment is an economical andpractical WDM system. It is employedwidely in the metro convergence, andaccess layers and the metro backbonelayer of medium-sized and small cities.● Low cost. Typically, its cost is onlyone third of other DWDM products.● Transparent transmission ofintegrated services. It supportsservices with variable rates from10M to 2.5G and various protocolslike SDH, POS, ATM, GE as wellas Fiber Channel, ESCON, FICONand DVB-ASI.● Flexible sub-rate convergence. Thesystem can implement convergenceof 4×Any, improving transportnetwork channel utilization ratios aswell as reducing bit operation cost.It can also provide 1+1 path andmultiplex section protection modesfor services.● Easy scalability with modulardesign. Along with the increase inbandwidth, it can realize smoothcapacity upgrades on conditionthat the existing services are notinterrupted. Ease of maintenance,compact characteristics and lowpower consumption mean that itsatisfies the numerous requirementsof installation environments.Rapidly growing market shareZ T E a t t a c h e s i m p o r t a n c e t olowering network construction costand improving operation efficiency.Backed by strong R&D capabilitiesZTE is continually innovating andhas developed a range of advancedsolution to help provide high levels ofservices to customers. ZTE has beensteadily increasing its global marketshare of optical products with a seriesof significant achievements made.On the international front, followingthe deployment of national trunk linesand transmission networks in manycountries including India, Pakistan,Indonesia, Bulgaria, Portugal, Venezuela,Morocco, Algeria and Zambia, ZTE hasestablished a long-term partnership withKorea Telecom (KT) and SK Telecom, asubsidiary of SK Group. The successionof continuing contracts indicate thatZTE’s optical transmission productshave already entered a period of stablegrowth.Growth in the Chinese domesticmarket for ZTE’s optical transportproducts has also been strong in 2006,with a 70% share of China Telecom’s 2006WDM national trunk line project wonearlier 2006. ZTE also bid successfullyfor China Unicom’s first 800G nationaltrunk line project, China Netcom’sfive national WDM trunk lines, andthe northwest ring project of ChinaRailcom.In 2006, ZTE announced manymilestone achievements. The companyhas entered its fourth-phase expansionof China Mobile’s west ring project (thelargest DWDM backbone in the world),installed a CWDM network for ShanxiMobile (the largest CWDM networkin the world). For the world’s highestaltitude rail service, the Qinghai-TibetRailway, ZTE not only provided awireless communication network butalso built a video monitoring transportnetwork–the largest commercial RPRproject in China.With powerful technical strengthand rich experience in networkconstruction, ZTE has establisheda leading position in the opticaltransport market. At present, ZTE’soptical products have been deployedby over 130 operators in more than 70countries. By the end of September2006, the accumulated length of WDMtransmission lines built by ZTE wasover 230,000km which, if stretchedend to end, would go around the earthfive and a half times.In 2007, ZTE, as always, willprovide superior products and servicesfor carriers around the world andwork with them to create a newchapter of global optical transmissiondevelopment.ZTE TECHNOLOGIES 17
