ZTE bags WDM network project from Thailand telecoms True

Ericsson signs 3G and 4G deal with Thailand telecoms True MobileZTE Corporation has bagged the bid from True, a telecom operator in Thailand, for building three networks as part of its beyond-100G backbone wavelength-division multiplexing (WDM) network project.

The Chinese telecom equipment maker claimed that it gained around 75 percent project share. The name of the other equipment vendor is not known. ZTE competes with Huawei, Ericsson and Nokia in the telecom infrastructure space.

ZTE said True is making investment in the backbone transmission networks to provide functions such as large capacity optical transport network (OTN) cross-connection, intelligent scheduling of optical networks, and long-distance transmission.

ZTE, the second largest optical network company, said the new 100G / 400G backbone transmission WDM network will improve True’s network capacity and promote its service growth in 3G/ long term evolution (LTE), fixed network, broadband and other fields.

ZTE has adopted 100G and beyond-100G WASON solution, PM-QPSK/PM-16QAM modulation and coherent reception technology, and the digital signal processing (DSP) algorithm and third-generation soft decision forward error correction (SD-FEC). The aim of ZTE is to achieve transmission without electronic relays in the entire network, reducing the cost of the network.

True will benefit from the software-defined optical networking (SDON) technology that makes optical network transmission more intelligent, effectively shortens the service deployment time, and improves the efficiency of network scheduling.

This project supports the embedded optical time domain reflectometer (OTDR) solution, and can achieve real-time monitoring of the fibre parameters and fault points in the existing network, improving network maintainability and reducing troubleshooting time.

This project 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.
