The city-state of Singapore is one of the wealthiest and most densely-populated nations in the world. Its MRT rail network forms the backbone of the city's public transport system. The government is currently expanding the network through the introduction of the Circle Line (CCL), a fully-underground orbital line connecting all the MRT routes into the city, at a cost of US$6.7 billion.
Set for completion in 2010, CCL will be 33.3 km long with 29 stations. Its purpose is to cut traveling time by enabling commuters to bypass busy interchanges.
The primary goal of the Land Transport Authority of Singapore is to provide the population of around 4.5 million, plus its 10 million yearly visitors, with a safe, efficient, and comfortable means of public transportation.
On completion, the CCL is expected to carry around 500,000 commuters. It will also be used by a large volume of tourists, the numbers of which are anticipated to increase with the imminent opening of two new integrated (casino and theme park) resorts in the city.
With such a high passenger flow, the monitoring and management of crowd control is of paramount importance. The Singapore government is also dedicated to countering potential terrorist threats to the country across its infrastructure. To address these issues, an extensive surveillance system has been installed incorporating Optelecom-NKF's fiber optic transmission equipment.
Singaporeans are extensive users of public transport and proud of their world-class system. CCL therefore requires state-of-the-art security equipment. Singapore Technologies Electronics, the system integrator for the surveillance project, chose Optelecom-NKF as an integral supplier for the system.
Optelecom-NKF will be responsible for providing the fiber optic transmission system within each of the CCL stations. The units will relay the collected video, data, and alarm signals from the surveillance cameras to each of the station control rooms. The project involves the deployment of four-channel digital video multiplexers, transmitters and receivers, which will connect the surveillance security system while maintaining high picture quality at all times.
For such a high-profile installation, the customer needed to have complete confidence in their suppliers. Optelecom-NKF met this expectation through its reputation for product reliability and by demonstrating technical support and local knowledge.
The project also demanded short lead times for installation, which Optelecom-NKF was able to meet as a result of close cooperation between its regional office and the factory.
