The growing trend to high fiber count cables?  

Deployments of 1,728 and 3,456 fiber cables are growing rapidly? They are used in everything from Hyperscale data centers to long haul backbones. These ultra/super high count cables present lots of opportunities and perhaps a few challenges along the way.

Today’s cable designs using standard flat and newer collapsible ribbons, along with options using 200um coated fibers, are providing new opportunities for high-density applications in a very small cable package.  We have seen 1728 fiber cables with an outer diameter under 0.90 inches with several options right around the 1” diameter size. These space-saving options require a little training and practice for handling and managing all those fibers, binders and new identification markings. They can provide significant savings in installation and splicing times, making some front end training worthwhile.

The first successful automatically switched rotary dial phone network was installed in La Porte, Indiana in 1892?

The inventor, Almon Brown Strowger was motivated because his undertaker business was losing clients to a competitor whose telephone operator wife was redirecting all calls for Strowger to her husband’s business. He formed the Strowger Automatic Telephone Exchange Company and installed and opened the first commercial exchange in his hometown of La Porte, Indiana on November 3, 1892, with about 75 subscribers and capacity for 99. He sold his patents to his associates in 1896 for $1800 and sold his share in the Automatic Electric Company for $10,000 in 1898. His patents subsequently sold to Bell Systems for $2.5 million in 1916!
