Fiber Optic Tutorials and FAQ's



Is the fiber you select up to speed? Can it go the distance? Choosing the right Fiber Optic Cable Core Type for your present and future needs.
In the chart provided, you can see different Fiber core types have vastly different limitations for speed and maximum distance.

Choosing a fiber cable for your installation can sometimes be confusing given all of the choices. In this article, we will attempt to clear up some of the confusion. Basically there are two attributes that you will need to consider and those are “cable material and construction” and “fiber type”. 

One of the most overlooked aspects of fiber optic maintenance and troubleshooting is keeping the fiber optic connector endfaces clean. We discuss in this informational tutorial how a dirty fiber connection can either slow down or completely inhibit network traffic. 

Pre-Terminated Fiber Optic Assembly
Learn the basics of Pre-Terminated Fiber Optic Assemblies and how to choose the right type for your application. This tutorial and cable selector will help with your next installation. Learn about cable jacket types, running through different environments, how to take an accurate measurement, installtion recomendations, and how to install the Pre-Terminated assembly. 

<h1> Mode Conditioning Cables </h1>
How do I run Gigabit Ethernet (LX) over my existing multimode fiber optic cable plant - use a mode conditioning cable. This tutorial and cable selector will provide useful information on how and when to use a mode conditioning cable. 


When designing a conduit run, the most important decision that you will have to make is it’s size. Consider not only the cables that will be installed now, but the likelihood of having to add cables in the future. “Fill factor” or conduit fill, states the maximum amount of space that the installed cables should occupy in a given size conduit, expressed as a percentage of the interior volume.


This tutorial goes in depth about what is fiber? It begins with the basics of what fiber is, and goes into terms that describe fiber, termination methods, fiber performance specifications, terms that describe the tools you will need to terminate fiber, and tools that describe the test equipment. 


Fiber optic "cable" refers to the complete assembly of fibers, strength members and jacket. Fiber optic cables come in lots of different types, depending on the number of fibers and how and where it will be installed. Choose cable carefully as the choice will affect how easy it is to install, splice or terminate and, most important, what it will cost!


We terminate fiber optic cable two ways - with connectors that can mate two fibers to create a temporary joint and/or connect the fiber to a piece of network gear or with splices which create a permanent joint between the two fibers. These terminations must be of the right style, installed in a manner that makes them have little light loss and protected against dirt or damage in use. No area of fiber optics has been given greater attention than termination.


After the cables are installed and terminated, it's time for testing. For every fiber optic cable plant, you will need to test for continuity, end-to-end loss and then troubleshoot the problems. If it's a long outside plant cable with intermediate splices, you will probably want to verify the individual splices with an OTDR also, since that's the only way to make sure that each one is good. 


The LANshack fiber tutorial guide has provided you with the basics, but now you need to decide where to go from here. There are many options for further training but first you need to figure out what your career choice is. This tutorial talks about training options for more in depth information and training moving foward. 


If fiber is more expensive, why have all the telephone networks been converted to fiber? And why are all the CATV systems converting to fiber too? Are their networks
 that different? Is there something they know we don't? Telcos use fiber to connect all their central offices and long distance switches because it has thousands of times the bandwidth of copper wire and can carry signals hundreds of times further before needing a repeater. 


Estimating is necessary to figure out what the job will cost you. First of all you'll need to set up a simple chart of all the details: the items you will need to purchase (i.e. cable, connectors, etc) and their costs. You will also need to add labor cost. We'll talk about doing your homework, considering yield, visiting the job site, and talking to the customer.


The five general types of Fiber Optic Cables shown below will cover 99% of the installations that you are likely to encounter: Indoor, Indoor/Outdoor, Outdoor, Interlocking Armor, and Outdoor Aerial with Messanger. Read on to find out more details, and how to purchase these cables for your next installation. 

The usual fiber specifications you will see are size, attenuation and bandwidth. While manufacturers have other specs that concern them, like numerical aperture (the acceptance angle of light into the fiber), ovality (how round the fiber is), concentricity of the core and cladding, etc., these specs do not affect you. 

Getting Started in Fiber Optics - You need tools, test equipment and - most of all - training! This guide will help you get started by providing very basic information  and demonstrating that you don't need to break the bank to break into the field. 


Here's an alphabetical glossary of fiber optic terms. You can search the list using the alphabetical index.

LANshack Tutorials 

LANshack.com has been on the internet for 19 years now and from our very start, we knew that tutorials were important for our customers. As a matter of fact, one of the tutorials we currently have was from our beginning and has been updated from time to time when new information was available. This tutorial is titled “Category 5 / 5E & Cat 6 Cabling Tutorial and FAQ's and remains to be one of our most popular tutorials. Over the years, it has been used by various prestigious colleges and  learning intuitions in their course study material.

Much of the material we write is based over 30 years of our personal field installation experience. We offer this material to you, our valued customer at no cost to you as a thank you.
