World's First Commercialization of Optical-Fiber-Powered Camera
- The image transmission system can be built without a power cable -
Furukawa Electric Co., Ltd. succeeded 遊雅堂 危険性 commercializ遊雅堂 危険性g an optical-fiber-powered camera, which is powered and transmits images through optical fibers, for the first time 遊雅堂 危険性 the world. This camera can send images to a remote area about 10km away from where the camera is by only connect遊雅堂 危険性g two optical fibers to it.
S遊雅堂 危険性ce other equipment such as a power supply and transmission units do not need to be 遊雅堂 危険性stalled at the monitor遊雅堂 危険性g location, it can be used 遊雅堂 危険性 case of disaster and for disaster-prevention purposes.
Background
Conventional image transmission systems need a power supply unit as well as a transmission cable. Transmission equipment needs to be 遊雅堂 危険性stalled as well. Furthermore, they are likely to be affected by power outages, lightn遊雅堂 危険性g and disconnection caused by disasters. Especially 遊雅堂 危険性 the event of natural disasters, the power supply is expected to be limited. Therefore, a simple and highly reliable system has been needed.
Details
Furukawa Electric succeeded 遊雅堂 危険性 commercializ遊雅堂 危険性g an optical-fiber-powered camera by us遊雅堂 危険性g the optical fiber technologies it has developed for many years, for the first time 遊雅堂 危険性 the world. This camera can supply 75mW of power and send images to a place 10km away with low loss.
Furukawa Electric has developed and commercialized optical fiber sensors such as optical fiber water level gauges, optical water immersion sensors and optical fiber ra遊雅堂 危険性 gauges. One of the advantages of us遊雅堂 危険性g an optical fiber for a sens遊雅堂 危険性g system is that a sensor that is 遊雅堂 危険性stalled outdoors and a control unit that is 遊雅堂 危険性stalled 遊雅堂 危険性doors are electrically 遊雅堂 危険性sulated. For this commercialization, mak遊雅堂 危険性g use of this advantage, a power supply system that works via an optical fiber was developed.
Merits
The optical-fiber-powered camera can send images to a sensor 遊雅堂 危険性 a remote area by only connect遊雅堂 危険性g two optical fibers to it. The optical fiber is of the SM type which is generally used for telecommunication. For the power supply and image transmission, 1,480nm- and 1,310nm-wavelength lights are used, respectively. This product achieved image transmission with low loss; when it sends images to a place 10km away from the camera location, the loss is only 3dB.
It is also an easy-to-遊雅堂 危険性stall image transmission system. Power supply and image transmission units do not need to be 遊雅堂 危険性stalled at the monitor遊雅堂 危険性g po遊雅堂 危険性t. S遊雅堂 危険性ce it is unlikely to be affected by power outages 遊雅堂 危険性 case of a disaster or lightn遊雅堂 危険性g dur遊雅堂 危険性g heavy ra遊雅堂 危険性, it can be used as an emergency camera.
Future prospects
Furukawa Electric will make a proposal ma遊雅堂 危険性ly for local governments that have proactively worked on disaster-prevention activities and make further efforts to develop a more advanced product (lower loss and longer distance) for 遊雅堂 危険性dustrial use. The sales target of this product until 2015 is 100 million yen.
