Understanding The Difference Between Single-mode and Multimode Fiber

Posted by John Kornegay on Tue, Sep 25, 2018 @ 09:09 AM

There are so many cable options available the one might wonder where to start. This article will set you on the right path in the decision process. Let’s begin by focusing on single mode and multimode fiber optic cables.

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.

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.

Single Mode Optical Fibers by ITU Standards

Posted by Kevin Miller on Wed, May 18, 2011 @ 14:05 PM

The International Telecommunication Union (ITU) is a United Nations agency involved with the development of worldwide standards for communications technology.  With the explosive growth and use of fiber optic technology around the world, a number of single mode optical fibers have been designed over the years for various applications.  Since integration of a variety of optical fibers and systems is required to achieve seamless worldwide communication, ITU developed standards for fibers that help to ensure this can happen.

Commonly Used Single Mode Optical Fibers

Posted by Kevin Miller on Thu, Jun 3, 2010 @ 13:06 PM

Single Mode Optical Fibers are commonly used throughout the world for fiber optic communications,  as they offer narrower modal dispersion characteristics, making them more suitable (than multimode fibers) for medium and longer distance transmissions.  With several manufacturers, as well as industry standards, it is important to understand what fibers are available when designing, installing, and testing fiber optic products and systems.
