These cables are just three inches thick, carry just a few optic fibers, and have total capacities of between 40Gbps and 10Tbps, and latencies that are close to the speed of light and just a few milliseconds in duration. I’ve heard stories about how some species of sharks also used to gnaw on copper cabling at the bottom of the ocean. I also got to see the Porthcurno telegraph museum when I was in England 5 years ago.  Amazing how 150 years ago they laid all that cable, and the manpower it took to do it. I’m constantly amazed by the infrastructure that was rolled out during the Industrial Revolution.
I have a question: apart from the cables you laid, did you lay any underground equipment like DWDM or repeaters? Fiber optic cables are actually about 1″ diameter, slightly smaller than the copper cables which carried signals across the Atlantic from 1858 until 1988.

Business Flowcharting Tool - The easiest way to draw a new flowchart is by starting with a CuteDraw templates and samples.
Flowcharts use special shapes to represent different types of actions or steps in a process. Templates and examples listed under this category have all the special settings for grid snaps, line- and shape-linking, wizards, and other crucial attributes that make it easy to draw a flowchart.

You can start with an example that closely resembles your project or you can start with a blank page by choosing New Document. Please feel free to download and evaluate our free trial version to get a better understanding of our products.
Terra firma links between cities and cables that run alongside roads and into houses and officers are certainly impressive — and without them we wouldn’t have an internet!
While satellite data links can be in the gigabit range, the high latency of bouncing a signal through a point that is rather far away (35,000 km, 22,000 miles) makes them unsuitable for many consumer internet services. I had the priviledge to work on two of the world’s largest undersea cable, COMPAC and ANZCAN. Steps in a process are shown with symbolic shapes, and the flow of the process is indicated with arrows connecting the symbols. You'll also find additional flowcharting symbols with professionally-designed styles and more.
I was part of the ANZCAN team in the South Pacific for a landing site and maintained the last years of COMPAC.
Computer programmers popularized flowcharts in the 1960's, using them to map the logic of programs. To get from London to Tokyo, your packets can traverse Europe, the Mediterranean, the Red Sea, the Arabian Sea, the Indian Ocean, and finally the South China Sea — or they can hop across the Atlantic, the entirety of continental North America, and then long haul over the Pacific.

The technology is so amazingand when you tell newbies how sea-water is used for telecommunications, they get stunned. It comprises of 72 fibre pairs – the whole of wikipedia can be sent through one fibre pair of the cable in one second! Reproduction in whole or in part in any form or medium without express written permission of Ziff Davis, LLC. In quality improvement work, flowcharts are particularly useful for displaying how a process currently functions or could ideally function. Flowcharts can help you see whether the steps of a process are logical, uncover problems or miscommunications, define the boundaries of a process, and develop a common base of knowledge about a process. Flowcharting a process often brings to light redundancies, delays, dead ends, and indirect paths that would otherwise remain unnoticed or ignored. But flowcharts don't work if they aren't accurate, if team members are afraid to describe what actually happens, or if the team is too far removed from the actual workings of the process.
