An Introduction to Large Core Optical Fibers

Posted by George Zhu on Thu, Sep 28, 2017 @ 10:09 AM

The most common multimode optical fibers, which allow multiple light modes to propogate along the link simultaneously, are designed with a core diameter size of 50µm for for high-speed communications networks.  You may recognize these types of fibers by industry specifications such as OM2, OM3, and OM4 or by brand names like Corning® ClearCurve® and OFS® LaserWave®.

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.

Get The Most Out Of Bare Optical Fiber Spools

Posted by Kevin Miller on Thu, Apr 4, 2013 @ 17:04 PM

If your company is like most that are involved with building or utilizing fiber optic systems, chances are you have a few spools of bare optical fiber laying around the lab.  Since it is critical to ensure fiber-based equipment works as intended prior to deployment in the field, it is a recommended and common practice for engineers to simulate networks using spools of bare optical fiber.  Because there have been a variety of different fibers available over the years, engineers can end up with fair amount of spools at their disposal.

Chromatic Dispersion in Optical Fibers

Posted by Kevin Miller on Wed, Aug 24, 2011 @ 12:08 PM

Chromatic dispersion is a phenomenon that is an important factor in fiber optic communications.  It is the result of the different colors, or wavelengths, in a light beam arriving at their destination at slightly different times.  The result is a spreading, or dispersion, of the on-off light pulses that convey digital information.  Special care must be taken to compensate for this dispersion so that the optical fiber delivers its maximum capacity.

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.

Why Test Fiber Optic Equipment Using Real Optical Fiber?

Posted by Kevin Miller on Thu, Jun 10, 2010 @ 15:06 PM

When testing fiber optic equipment intended for longer distances during the development/certification stages, it is vital that engineers ensure their products will operate as intended once installed in the field.  In order to do this, there are a few alternative methods that have been used to accomplish this task.  As a leading provider of network simulation platforms containing real optical fiber spools, questions we commonly receive include:
