Types of Fiber Optic 2008-04-06 08:42:00 There are two basic types of fiber:
Multi Mode Optic
al Fiber
:Used to transmit many signals per fiber (Multi Mode generally are used for in computer networks, lan applications)
MultiMode Optical Fiber produce as 50 / 125 and 62.5 / 125 ( Core / Cladding diameter Microns)
Single Mode Optical Fiber: Used to transmit one signal per fiber (Single Mode generally are used for in telephones and cable tv applications)
SingleMode Optical Fiber produce as 8 / 125 and 9 / 125 ( Core / Cladding diameter Microns)
Types of fiber optic cable of Design
Two basic cable designs are:
Loose-Tube Fiber ( indoor / Outdoor Loose-Tube) : fiber optic cable filled
with a water blocking gel. Loose-tube cables generally are used for outside-plant
installation in aerial, duct and direct-buried applicati
Basic Information 2008-04-01 15:53:00 What is Optical Fiber Cable?
Optical cables used to transmit light signals over long distances.
It has basic three parts:
Core: Thin Glass center of the Optical Fiber Cable where the light signal travels.
Cladding: Outer Material surrounding the core. Reflects the light signals back
into the core.
Coating:
Protects the Optical fiber from damage.
How to Work Fiber Optic Transmissions?
Optical fiber transmissions are light Signals instead of voltage Signals.The
light signals in a fiber optic cable travels through the core and Cladding Reflects
the light signals back into the core.Light source is a laser or some kind of
LED (light emitting diode).

Disadvantages 2008-03-26 13:22:00 Disadvantages of Fiber Optic Cabling
Adding additional nodes is difficult
Cost of transmission equipment is Higher than copper
Cost of installation is Higher than copper
Difficult to Install
Expensive over short distance (less 5 km)
Requires highly skilled installers
Advantages 2008-03-26 10:52:00 Advantages of Fiber Optic Cabling
Fiber Optic Cabling Is Environmentally friendly
High Bandwidth Over Long Distances- Speed
Lower signal attenuation (loss)
Immunity to Electromagnetic Interference - Electrical Isolation - Nonconductive
No crosstalk
Lower bit error rates
Signal (data) Security (Better Security)
No common ground required
Freedom from short circuit and sparks
Decreased size and weight
Environmental Protection
Resistant to radiation , corrosion and temperature variations
Improved ruggedness and flexibility
Less restrictive in harsh environments
Lower installation cost - Less expensive

Glossary-Cabling Definitions 2008-02-21 20:05:00 GLOSSARY
Adapter
A device to join and align two connectors.( optical fiber duplex: A mechanical
device designed to align and join two duplex optical fiber connectors (plugs)
to form an optical duplex connection.)
Axial ray A light ray that travels along the axis of a fiber optic cable.
Bend loss
Losses due to bends in the fiber. The loss increases as the bend radius decreases.
Bend radius
Minimum bend radius. The smallest acceptable bend for a fiber or cable before
bend loss is apparent.
Buffer - A protective layer over the fiber optic cable, such as a coating,
an inner jacket, or a hard tube. The primary buffer, next to the cladding, is
250 µm in diameter. A secondary buffer of 900 µm is used on indoor cables.
Buffer coating -A protective layer, such as an acry Read more:Glossary
