Fiber Optic Splitters - Common Types

Posted by Kevin Miller on Wed, Sep 28, 2011 @ 10:09 AM

Fiber optic splitters enable a signal on an optical fiber to be distributed among two or more fibers.  Since splitters contain no electronics nor require power, they are an integral component and widely used in most fiber optic networks.  As a basic example, the diagram below shows how light in a single input fiber can split between four individual fibers (1x4):

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.

Latency in Fiber Optic Networks

Posted by Kevin Miller on Mon, Aug 1, 2011 @ 11:08 AM

The term latency refers to the time delay in a particular system. For communications systems, latency is an important factor, because transmission delays can affect the quality and reliability of the system. In the case of fiber optic networks, latency is the time delay that affects light as it travels through the fiber optic network.

Benchmarking CATV System Performance with OMI

Posted by Kevin Miller on Tue, May 24, 2011 @ 10:05 AM

Benchmarking is a term that is used widely to evaluate one's performance against a standard, which is typically based on the best organizations or processes in your industry.  In most cases, the goals of benchmarking are often centered around key factors such as quality, time, and cost.  In the performance of fiber optic communications systems, benchmarking generally applies to the performance quality of the information provided, but on a second level has an extremely significant impact on both time and cost.

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.
