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.

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.

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.
