Optic Cables Work
The traditional method of data transmission over copper cables is
accomplished by transmitting electrons over a copper conductor. Fiber
transmit a digital signal via pulses of light through a very thin
strand of glass. Fiber strands (the core of the fiber optic cable)
are extremely thin, no thicker than a human hair. The core is surrounded
by a cladding which reflects the light back into the core and eliminates
light from escaping the cable.
optic cable chain works in the following manner. At the
one end, the fiber optic cable
is connected to a transmitter. The transmitter converts electronic
pulses into light pulses and sends the optical signal through the
fiber optic cable. At the other end, the fiber optic cable is plugged
into a receiver which decodes the optical signal back into digital
vs Singlemode Fiber
A "mode" in Fiber Optic
cable refers to the path in which light travels. Multimode
cables have a larger core diameter than that of singlemode cables.
This larger core diameter allows multiple pathways and several wavelengths
of light to be transmitted. Singlemode cables have a smaller core
diameter and only allow a single wavelength and pathway for light
to travel. Multimode fiber is commonly used in patch cable applications
such as fiber to the desktop or patch panel to equipment. Multimode
fiber is available in two sizes, 50 micron and 62.5 micron. Singlemode
fiber is typically used in network connections over long lengths and
is available in a core diameter of 9 microns (8.3 microns to be exact).
vs 62.5 micron fiber
Both 50 micron and 62.5 micron fiber optic cables use an LED or laser
light source. They are also used in the same networking applications.
The main difference between the two is that 50 micron fiber can support
3 times the bandwidth of 62.5 micron fiber. 50 micron fiber also supports
longer cable runs than 62.5 micron cable.

vs Duplex Cable
Simplex cable consists of a single fiber optic strand. Data is transmitted
in only a single direction, transmit to receive. Duplex cable consists
of two fiber optic strands side-by-side. One strand goes from transmit
to receive and the other strand connects receive to transmit. This
allows bi-directional communication between devices.
There are a variety of fiber optic connectors. Below is a common list:

known as SPF, Small Form Factor & Mini Gibic
& Disadvantages of Fiber Optic cable
There are many advantages and disadvantages in using fiber optic cable
instead of copper cable. One advantage is that fiber cables support
longer cable runs than copper. In addition, data is transmitted at
greater speeds and higher bandwidths than over copper cables. The
major disadvantages of fiber optic cables are cost and durability.
Fiber cables are more expensive than copper cables and much more delicate.
