WCWL Communications Sdn Bhd started to participate in MRT line 1 on March 2016. We were the contractor that responsible for fiber optic splicing on track and station admin and TER rooms. Besides, we were the sole contractor to be assigned to do WDCS (Wideband digital cross-connect system) digital backbone fiber optic 4 core SWA (steel wire armoured) splicing and power cable terminations. After fiber optic cable splicing then we have to deploy our tester team to be on ground along the trackside to conduct fiber testing by using OLTS (optical loss test set) for each core cables which is a ring topology.
We have encountered some challenges during our deployment on trackside work like weather is our main constraint as there were raining season therefore we have to deploy more teams in order to achieve our time line. Moreover, the allowed time frame given was short as the train already energized so we only allow to work at night shift. Nevertheless, we were to deploy more manpower in the night shift in order to rush up the work. Although with all the challenges, our team mates able to overcome it and ultimately WCWL Communications Sdn Bhd has passed the PICO conducted by PDP for WDCS from Northern to Southern line.
