ZTE Corporation, a major international provider of telecommunications, enterprise and consumer technology solutions for the Mobile Internet, today announced it has won the bid for three networks in True’s beyond-100G backbone wavelength-division multiplexing (WDM) network project in Thailand, gaining around 75 percent project share. The backbone transmission networks will enable True to provide valuable functions such as ultra-large capacity optical transport network (OTN) cross-connection, intelligent scheduling of optical networks, and ultra-long-distance transmission, helping True adapt to future service development and follow-up evolution.
ZTE is committed to helping True create a large-capacity, high-performance and high-stability backbone dense wavelength division multiplexing (DWDM) network. The new 100G/400G backbone transmission WDM network will greatly improve True’s network capacity and effectively promote its service growth in 3G/ long term evolution (LTE), fixed network, broadband and other fields.
In this project, ZTE has adopted the 100G and beyond-100G WASON solution, industry-leading PM-QPSK/PM-16QAM modulation and coherent reception technology, and the industry-leading digital signal processing (DSP) algorithm and third-generation soft decision forward error correction (SD-FEC) to achieve transmission without electronic relays in the entire network, greatly reducing the cost of the network. The software-defined optical networking (SDON) technology makes optical network transmission more intelligent, effectively shortens the service deployment time, and greatly improves the efficiency of network scheduling. In addition, this project supports the industry-leading embedded optical time domain reflectometer (OTDR) solution, can achieve comprehensive and real-time monitoring of the fibre parameters and fault points in the existing network, greatly improving network maintainability and reducing troubleshooting time. This project also provides the colourless directionless contationless flexgrid, reconfigurable optical add-drop multiplexer (CDCF ROADM) function, which can fully meet the operator’s requirements for the transparent transmission, flexible scheduling, aggregation, management, and monitoring of massive data services.
With more than 300 network application cases and a total length of 300,000 km network fibre, ZTE maintains an industry-leading position in the field of 100 Gbps/beyond-100G innovative technologies. According to a 2016 annual report released by OVUM, an internationally renowned consulting firm, ZTE ranks second for its share in the optical network market.
