"people's posts and telecommunications" editor's choice award released on december 28th, 2012,hengtong optical-electric co. ltd. ocean engineering cable system solutions owned "submarine cable excellent product" award. this award reflects a high degree of recognition and praise of industry experts to hengtong optical-electric co. ltd submarine cable products and solutions. marine optical transmission systems engineering is a world recognized high technical difficulty and wide coverage. this system includs cable products and accessories, system design and equipment, marine construction and other parts. the large length undersea production requirements are very high, including the length of submarine cable manufacturing, high reliability requirements, water tightness, high resistance to water pressure. the same time, due to the complexity of the seabed topography, ocean climate variability, submarine cable laying is very difficult. therefore, for a long time, submarine optical transmission systems engineering is almost monopolized by foreign companies.
