Remote Fiber Test Systems – Increasing Optical Network Availability

Posted by Kevin Miller on Tue, Aug 14, 2012 @ 10:08 AM

With most of the world now relying on fiber optic systems for communication, a key component to ensuring a high level of performance from operators is network monitoring.  When we think of network monitoring, much of the focus is usually on the equipment itself, as well as the management of all the data flowing through the system.  As a result, an area often overlooked when deploying and monitoring a network is the actual fiber optic cable, through which all the data is sent from one location to another.

Calculating Optical Fiber Latency

Posted by Kevin Miller on Mon, Jan 9, 2012 @ 15:01 PM

Latency is a term that is used to describe a time delay in a transmission medium such as a vacuum, air, or a fiber optic waveguide.  In free space, light travels at 299,792,458 meters per second.  This equates to 299.792 meters per microsecond (µs) or 3.34µs per kilometer.  In fiber optics, the latency of the fiber is the time it takes for light to travel a specified distance through the glass core of the fiber.  Light moving through the fiber optic core will travel slower than light through a vacuum because of the differences of the refractive index of light in free space and in the glass.

OTDR Launch Fibers - Importance and Usage

Posted by Kevin Miller on Tue, Nov 29, 2011 @ 14:11 PM

An Optical Time Domain Reflectometer (OTDR) is an optical measurement instrument designed to detect faults, splices and bends in optical fiber cables.  It functions by launching pulses of light into the optical fiber and measuring the back reflections created by the faults, splices, and bends.  It can identify the exact location of the fault by measuring the round trip time from the launch to the detection of the reflected returning pulse.  The time is determined by the speed of light in the glass core of the optical fiber.

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.

Fiber Network Simulation – 4 Tips for Improving Test Results

Posted by Kevin Miller on Tue, Jun 28, 2011 @ 10:06 AM

Engineers performing fiber optic network simulation testing with the goal of certifying that their equipment will work as intended once deployed in the field, often require the use of optical fiber spools to complete these procedures.  Since it is crucial these tests produce both correct and reliable results, below are some tips for ensuring the most positive results.
