2018 / Did You Know...

That the average broadband speed worldwide is projected to nearly double by 2021? / August 2018

The global average broadband speed continues to grow and will nearly double from 2016 to 2021, from 27.5 Mbps to 53.0 Mbps.  Several factors influence the fixed broadband-speed forecast, including the deployment and adoption of Fiber to the Home (FTTH), high speed DSL and cable broadband penetration, as well as overall broadband penetration.  Japan, South Korea and Sweden are the countries that lead in terms of broadband internet speed largely because of their wide deployment of FTTH.

That OTDRs operate like optical radar? / July 2018

OTDRs operate like an optical radar, injecting pulses of light into the fiber from one end and measuring reflections and backscatter that is returned to the OTDR. Loss due to fusion splices, connectors, breaks or macro-bends reduce the amount of returned backscatter. The OTDR records returned backscatter and reflections vs. time and may present this as a trace showing optical loss vs. distance. Intelligent algorithms interpret the trace to locate, identify and characterize detected network start, end, components and faults.

The U.S. now has more wireless than wired connections? / May 2018

Although many in the fiber industry express concers over the growth of wireless technologies, fiber optic backbones are still the most reliable and economical way to move that IP voice and data. Their analysis is also projecting that Internet Protocol traffic will grow 2.5x over the next 5 years. All that extra bandwidth demand is good for the fiber optic industry!

There are 448 submarine cables currently in service around the world, covering a distance of over 1.2 million kilometers? / April 2018

One of the newest subsea cables was put into service thanks to funding from Microsoft and Facebook while Telxius will operate the span. The 'Marea' subsea cable, with just 8 fiber pairs, runs from Virginia Beach, VA to Bilbao, Spain and is capable of transmitting up to 160 terabits of data per second, becoming the highest capacity subsea cable across the Atlantic. From design through construction, Marea was completed in less than two years - nearly three times faster than the typical subsea cable project.

You can’t strip off a fiber’s cladding? / March 2018

In glass optical fibers, the core and cladding are actually two layers of one solid, inseparable, piece of glass. Each layer has its own distinct optical properties, and both are critical in order for light to travel through the fiber. The light is transmitted through the core by continuously reflecting off of the cladding through a principle known as “total internal reflection.” Without the cladding layer, all of the light would escape rather than travel further down the fiber.

The first televised broadcast using fiber optics was at the Winter Olympics? / February 2018

Broadcasters for the 1980 Winter Olympics in Lake Placid, New York, originally had coaxial cables installed to televise their coverage, and multimode fiber was installed at the last minute to serve as a backup video feed. However, the fiber transmission was so reliable and high quality, it soon took over as the primary video feed for the entire Olympics broadcast.

That in 2017, the most common cause of fiber network failures or trouble calls is still dirty or damaged connectors? / January 2018

Industry experts have been talking about this for years. There are many great products available that will keep your connectors clean and your losses low. Whether you use sticks or ‘one-clicks’, cassettes, wipes, dry or wet cleaners – be sure they are designed specifically for fiber optic use. Clean and inspect before you connect!
