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.

The Positive Impact of Using Optical Fibers on Cell Towers

Posted by Jonathan Tuck on Wed, Sep 2, 2015 @ 14:09 PM

While fiber optic technology has been utilized for many years in the communications industry, consumers generally identify with the role that it plays in wired communications such as Cable TV, Fiber-To-The-Home, and the related networking equipment.  However, what most overlook or do not realize is the significant impact that deploying optical fibers has also had on something consumers use every day – mobile devices.  In order to achieve the high speed data levels that we have become accustomed to when using mobile devices, cell towers and their supporting networks had to be retrofitted with optical fiber cables.

Upgrading to 40/100 Gigabit Ethernet? Consider the Implications on your Multimode Fiber Infrastructure

Posted by OJ Johnston on Mon, May 11, 2015 @ 17:05 PM

While many enterprises are considering the move to a 40/100G ethernet infrastructure, often they overlook the impact of remaining with a multimode fiber infrastructure. While there is little difference in the infrastructure requirements of 10G ethernet for single-mode fiber and multimode fiber infrastructures, there is an exponential difference in 40/100G ethernet infrastructures. Many people tout the economics of MMF vs SMF lasers as the key reason for remaining with their MMF infrastructure; however, the savings achieved there will likely be erased by the increased cost of the passive optical infrastructure.

Solving Optical Multicast Challenges

Posted by Kevin Miller on Mon, Mar 17, 2014 @ 18:03 PM

There are many scenarios in today’s networks that require the replication of an optical signal, also known as optical multicast. Some of those scenarios include video feeds or data streams that need to reach multiple endpoints simultaneously. In other scenarios an expensive 40/100Gbps port may need to be replicated. In either case, current multicasting solutions create potential problems associated with congestion, cost, and latency.

Optical Switches: Symmetric and Asymmetric

Posted by Kevin Miller on Wed, Feb 5, 2014 @ 16:02 PM

While there are a number of aspects that can be discussed in regards to optical switching technology, the focus of this article is to provide information about two key categories of optical switches – symmetric and asymmetric.  The concept is very straightforward, but still important to understand when determining which type of optical switch will be most suitable for a given application.
