With the grand opening of the MTR Tuen Ma Line, transportation in Hong Kong is more convenient. The Tuen Ma Line – running approximately 56 km and serving 27 stations is the longest railway line in Hong Kong connecting the SCL “Tai Wai to Hung Hom section” with West Rail Line and the Tuen Ma Line Phase 1, providing more alternatives for passengers traveling to different districts. Despite the harsh installation environment, the fiber test at Tai Wai station was successful. Dust covers were added to the adaptors in order to prevent contamination of the adaptor and assure the best performance of the adaptors.
