Optical fiber line monitoring/management systems
These systems are used to optimize optical facilities maintenance and management work and make optical line and circuit design work easier. Specifically, these systems are responsible for such tasks as preventing optical fiber cable deterioration, gathering information during line stoppages, checking lines and routes when installing new equipment, helping to recover from damage, and examining network configuration. Furukawa Electric's monitoring and management systems have been adopted by local governments and the Ministry of Land, Infrastructure, Transport and Tourism, and are making it possible to detect damage to optical communications networks earlier and restore optical fiber cables damaged during accidents quicker.
Optical Fiber Intrusion Detection System
These sensors detect intrusion through a fence, and transmit the corresponding reduction in optical power as an alarm. They are used in such locations as airports, ports, mega solar power generation facilities, theme parks, factories, and power plants. As security continues to be enhanced and as trespass alert systems continue being developed for public and critical facilities, optical fence sensors are being developed and improved to take advantage of the characteristics of optical fiber cables.
Radar systems
Based on submillimeter wave radar (Note 1) used for in-vehicle equipment, these systems are mainly used for traffic counters (Note 2) and systems to detect reverse running vehicles (Note 3).
They provide an accurate picture of traffic conditions and road usage, and can be used for traffic planning, traffic policy development, and road improvement planning. They can also detect reverse running vehicles in real time, to prevent accidents from happening. These systems are insensitive to noise and weather, and can be installed on a pole at the side of the road, reducing maintenance and the risk of damage to the road surface.
(Note 1) Submillimeter wave radar is a radar system used in fields such as military, aviation, automobiles, and medicine for purposes including obstacle detection, distance measurement, speed measurement, and image generation.
(Note 2) Traffic counters are devices that measure traffic on roads and sidewalks. They detect the number of passing vehicles along with the position, speed, and size of vehicles to determine traffic conditions and road usage.
(Note 3) These systems detect reverse running vehicles on the road. They are used to prevent accidents and other hazards at locations such as intersections and on highways. When a reverse running vehicle is detected, the system alerts the driver through means such as alarms and displays, so that the issue can be handled quickly.
Optical multi-hop telecommunications systems (high availability solution)
These optical telecommunications systems are simple to configure but offer high availability.
"They provide stable communication at high speed through the use of an optical network with a flexible routing configuration, similar to a wireless network. They support a variety of network configurations such as tree, ring, and mesh, providing both flexibility and reliability."
"Unlike typical network switches, optical multi-hop does not require complex configuration and allows for quick and easy system setup. Network changes, such as new installations, expansions, relocations, and removals, can be implemented quickly. Optical multi-hop also offers autonomous decentralized routing functionality that can maintain communications even in the event of power outages or optical fiber disconnection. This high degree of fault tolerance ensures business continuity and uninterrupted operation of critical communications. "
