What Is Optical Fiber?

Posted by Tiffany San Souci on Thu, Jun 9, 2016 @ 09:06 AM

Optical fiber is made by drawing glass or plastic to a desired length and diameter (slightly larger than a human hair).  This flexible and highly pure fiber is most commonly used to transmit light for a wide range of applications including visible light displays, sensors, and high-speed communications networks which we will discuss in this article.

History of Optical Fiber

Posted by Tiffany San Souci on Mon, Jun 6, 2016 @ 09:06 AM

The first instances of glass being drawn into fibers date back to the Roman times, however it was not until the 1790’s that a pair of French brothers named Chappe, invented the first “optical telegraph”. This primitive system was made up of towers outfitted with a series of lights that operators could use to relay messages back and forth.

WANem As A Delay Simulator

Posted by Tiffany San Souci on Tue, Apr 26, 2016 @ 09:04 AM

Wide Area Network Emulators, or WANem, are designed to simulate WAN connections for use in laboratory settings, and makes for a good delay simulator as well.

By calculating the interactions between different network entities, WAN emulation creates artificial delay, bandwidth constraints and other impediments and functions.

This functions as a way to gauge applications and protocols against actual conditions. WAN characteristics like packet loss, disconnections, jitter, and time delay can be mimicked over a transparent application gateway with a WANem. This unique test condition allows users to bring the internet into their development, laboratory or test environment.
