LANGHORNE, Pa., 28 March 2008. Optellios Inc.'s fiber-optic perimeter intrusion detection system has passed the final acceptance test for securing Qinghai-Tibet railway in China. The company's FiberPatrol system was chosen for final testing after it outperformed competition in head-to-head engineering trials in September 2007.
FiberPatrol was the only fiber-optic sensor to pass the trials, which it did by demonstrating accurate intrusion detection with zero false alarms, despite windy conditions and passing trains. The FiberPatrol system performed well during the final test, which took place at a remote section of the railroad.
Qinghai-Tibet railroad, completed in 2005 and opened for operation the following year, is the world's highest, reaching a peak altitude of 3.152 miles above sea level.
The Qinghai-Tibet Railway Surveillance System project covers the railway section from Golmud, a city in China's Qinghai province, to Lhasa, the capital city of the Tibet Autonomous Region. The section's total length is 710 miles, 80 percent of which lies at an altitude of at least 2.5 miles; it includes 45 train stations, and multiple tunnels and bridges. The project adopts some of the most advanced security and surveillance technologies, providing real-time monitoring of train operation and environmental conditions, and ensuring safety of travel.
"We are very impressed by the capabilities and performance of FiberPatrol. We have tested several fiber optic sensors for railway security and FiberPatrol stood out as the top performer from start to finish," says Fang Jingen, vice president of Qinghai-Tibet Railway Co., an affiliate of China Ministry of Railway.
Based on a unique distributed fiber-optic technology, FiberPatrol intrusion detection systems can monitor many miles of sensing cable and report accurate GPS location of any intrusion attempt.
During tests, GPS coordinates of alarms were sent to a video verification system, provided and integrated by TeraMage Technologies, which then used the coordinates to automatically control security cameras. The integrated system brought real-time video, capturing the scene of intrusion, to the front panel of the monitoring station.
"FiberPatrol has made it possible to monitor a large length of perimeter by accurately detecting intrusion location and virtually eliminating all false alarms," says Alvin Guo, executive VP and CTO of TeraMage Technologies. TeraMage Technologies has been offering Optellios products on the Chinese market since the two companies signed a distribution agreement in 2005.
