Three U.S. communications operators develop laser broadband technology

Recently, three U.
S.
communications carriers are testing a laser broadband technology that uses wireless and laser links to transmit data at high speeds over distances of up to ten kilometers
.
A telecom operator in Mexico is also deploying the technology
.

The inventor of this technology is AOptix, which believes that laser communication is cheaper and more practical, and will become an alternative
to optical fiber.
Digging trenches and laying optical fibers in dense urban areas requires layers of approval, and the actual operation is very
difficult.
Nigeria began laying high-capacity submarine cables to connect to Europe in 2013 and is currently building internet infrastructure, precisely in the process of introducing laser broadband technology
.

On June 3 this year, AOptix announced that it has partnered with Anova Technologies to use this technology in New Jersey to complete the computer that connected the NASDAQ stock market to the global operator of the securities derivatives market BATS, and it only takes a few nanoseconds to complete the data transfer
.
Michael Klayko, CEO of AOptix, said the connection between the two financial institutions perfectly highlights the strength
of AOptix's laser broadband technology.

Chandra Pusarla, senior vice president of products and technology at AOpitx, said that many rural areas and developing countries lack fiber optic infrastructure, and the fastest way to increase network speeds is to use AOpitx's wireless towers, which can transmit data at speeds of up to 2Gbps
per second.

Psala pointed out that today's mobile phone users are increasingly demanding mobile data transmission, and this service is particularly attractive
to mobile operators.
Many U.
S.
carriers have upgraded the copper lines connecting cell phone base stations to fiber, but progress has been slow and expensive
.
It costs up to $800,000
to bury a kilometer of fiber optic cable in the suburbs of New York City.

AOptix's technology uses a box the size of a coffee table, with an infrared laser emitter peeking out of a small window on the front of the box and a directional millimeter-wave receiver
next to the transmitter.
The two units in the box form a wireless link
with another identical box 10 kilometers away.
Multiple such links are connected together to form a link
of any length.

AOptix combines laser technology with wireless connectivity to make up for the lack of
using a single technology.
The laser beam is blocked by fog, while the millimeter-wave wireless signal is absorbed
by rain.
Psala said that the redundant routing data generated by the AOptix device can guarantee a rate of 2Gbps per second in any weather situation, with a low
failure rate.

Due to the limitations of radio frequency, ordinary fiber optics may be 10 times or more
faster than laser broadband.
But Psala believes that the convenience of the technology can compensate for this, and in the future the rate of laser broadband may increase to 4Gbps or higher
.

The wireless laser unit in the AOptix device can automatically move to compensate for tower sway
caused by wind.
AOptix originally developed this laser broadband technology for the Pentagon, designing systems that control laser beams to propagate
data between ground stations, drones and fighter jets.

Psala denied that U.
S.
carriers or Nigerian customers had tested
AOptix's technology in 2013.
But AOptix's early customers have shown a positive attitude
toward laser broadband technology.
Car-sa, Mexico's telecommunications operator, first opened multiple links and intends to use it to connect cell towers to provide network services
to the group's customers.
