Optical regeneration for 160 gigabit transmissions a triumph for IP surveillance.

03 April, 2008
Oki Electric have solved the problem of long distance high speed Gigabit transmissions with the development of signal regeneration technology that can span the globe.
Increasing demand for broadband internet in locations that are becoming increasingly more isolated from the data centres is driving signal transmission and switching technology to greater heights. The spin off for the security industry is network technology that continues to keep pace with the inflationary demands of Megapixel camera surveillance networks.

Security professionals want real-time, high quality images transmitted from multiple cameras in distant locations to centralised monitoring stations. If this isn't demanding enough on IT resources, they also want to share the network with other systems to facilitate integration and minimise infrastructure costs.

The answer to this puzzle is capacity. IT is a little like the motoring world of the pre-70s fuel crises when if you wanted horsepower, you couldn't beat cubic capacity and large engines delivered the needs of the power-hungry public. Now, of course, improved materials, design and efficiency have led to smaller engines packing as much horse power as engines twice their size from 30 years ago. Although transmission efficiencies and improved materials and components are providing benefits in the IT world as well, we're still hungry for capacity and this is what Oki is now delivering.

Remote megapixel cameras can perform pre-processing activities with on-board computing power to avoid unnecessary transmissions and bandwidth loading but when it decides to transmit, monitoring stations want the images crisp and instant. With 160 Gigabit Ethernet and regeneration technology to counteract signal attenuation, this is now achievable over virtually any distance providing a workable solution for two of the most challenging surveillance environments, namely pipelines and railways. In both of these applications, remote locations and the potential seriousness of public safety issues make reaction time a crucial factor.

Thanks to the technological advancements in switching and transmission systems by companies such as Oki, the abilities of the security industry to cope with such challenging applications continue to be an achievable reality.
