Bay Area trembled with Fiber Optic Cut

San Francisco Bay Area hit by another fiber optic cut on the 1st of this July, continuing the streak of incidents to interrupt internet services in the region and becoming headache for law enforcement authorities.

The latest event to disrupt the internet communication occurred near the city of Livermore. Reports confirmed unknown person or might be persons made their way through the manhole cover and ruined dozens of fiber optic cables out there. The FBI is investigating the Bay Area incident.

The network is operated by giant providers such as Level 3 Communications. These companies own huge capacity to transfer data and also serve as third party providers, therefor it is highly predicted the internet services would be greatly slowed down in several cities on the West Coast.

Microsoft announced the break down for its Azure services in the Bay Area due to Livermore fiber optics cutting. Also the Wave Broadband told to be affected by the incident. The spokesman of Wave told their Customers in Sacramento suburbs lost its services for a while and faced slower internet connection.

There have 11 similar kind of incidents been reported in the Bay Area over the past year. Five events were reported in Fremont whereas other was happened in Walnut Creek, San Jose and Berkeley.

The Liver more incident is the latest in internet disruption streak. FBI is investigating the roots of these events. It is still not confirmed whether the same hands are behind them.

Researchers achieved Epic fiber optic range

Fiber optic cables are leader in the internet connectivity and esteemed to be the ultimate solution to send data over larger distances. Nevertheless, there are few limitations – as engineers hitch up power to send up more data through fiber optics at larger distance with faster pace, but the distortion setbacks the determined range.

A researcher team at the University of California, San Diego have covered the milestone to surpass a long-standing obstacle in the data transmission rates in the fiber optics architecture.

Nikola Alic, the leading member in the project, lightened up what researchers have accomplished, “Today’s fiber optic systems are a little like quicksand. In the quicksand, the more you try to struggle, the quicker you’ll be sunk. In the case of fiber optic cables, the more you add up power to boost you signal, the more distortion comes along the way, preventing long reach. We’ve achieved the milestone to rid of power limit which, in turn, lets you achieve greater distance without needing a repeater.”

Epic Transmission Distance

The achievement of wideband ‘frequency combs’ in the optical fiber networking is the key innovation by the UC San Diego researchers.

“Removing the distortion factors in advance that will occur in the optical fiber” makes it possible to calculate the crosstalk in the cables.

Using the revolutionizing technique, researchers were able to send data over record breaking 12,000 KM (7,500 miles approx.) via fiber optic cables. No repeaters were used in the process but the standard amplifiers. In the normal process repeaters are grounded after every 100 kilometers to avoid signals distortion by noise.
