US R&D laser broadband technology
Recently, three US telecommunications carrier is testing a laser broadband technology that uses wireless and high-speed data link laser, the transmission distance of up to ten kilometers. A telecom operator in Mexico are deploying the technology.
The inventors of this technology is AOptix company, the company that laser communication cheaper and more practical, will become a substitute for fiber. In dense urban areas trenching of laying fiber to go through layers of approval, but the actual operation is very difficult. Nigeria in 2013 to begin construction of high-capacity submarine cable from Europe, is currently building the Internet infrastructure, it is the introduction of laser broadband technology.
June 3 this year, AOptix announced a partnership with Anova Technologies in New Jersey, the company has to use the technology to complete the connection Nasdaq stock market and securities derivatives market operator BATS Global computer before, just a few nanoseconds to data transfer is complete. AOptix CEO Mike Coley Cole (Michael Klayko), said the connection between the two financial institutions AOptix perfectly highlights the strength of laser broadband technology.
Senior vice president of products and technology AOpitx Uppsala Chandra (Chandra Pusarla) said that many rural areas and developing countries lack fiber infrastructure, improving the speed more quick way is to use AOpitx's wireless towers, data Transmission speeds of up to 2Gbps per second.
Uppsala pointed out that today's mobile phone users increasingly high data transmission requirements, this service is particularly attractive for mobile operators. Many US operators have to connect your phone to upgrade to fiber optic base of copper, but progress is slow, too costly. In the suburbs of New York City's laying one km of fiber optic cable it costs up to $ 800,000.
AOptix technology uses a coffee table-sized box, an infrared laser transmitter unearthed from the front of the box a small window next to the millimeter-wave transmitter to set a directional receiver. The box is the same in both devices and other far away as 10 kilometers away form a wireless link. A plurality of such link together to form a link of any length.
AOptix laser technology and wireless connectivity technologies, to make up for the lack of a technology alone. The laser beam is blocked by the fog, and millimeter wave radio signal can be absorbed rain. Uppsala, said redundant routing data generated AOptix device can ensure that in any weather conditions to achieve 2Gbps per second rate, and low failure rate.
Due to the limitations of RF, ordinary laser broadband fiber may be greater than 10 times faster or more. But Uppsala believe the convenience of this technology can make up for it, may be increased to 4Gbps or higher rate in future broadband laser.
AOptix wireless devices laser device can automatically move to compensate for wind caused the towers sway. AOptix was originally developed for the Pentagon this laser broadband technology designed to control the laser beam system to enable data between ground stations, unmanned aerial vehicles and fighter jets spread.
Uppsala denied that US carriers or Nigeria has customers in 2013. AOptix techniques were tested. But early customers AOptix broadband technology for laser shows positive attitude. Mexican telecom company Car-sa first open multiple links, intends to use it to connect to cell towers, providing network services to corporate customers.
