Hi all,
First of all I would like to clear a very big confusion among the people regarding armored fiber optic cable; most of the people think that fiber optic armored cable means cable with metal protection. Its totally wrong concept.
First we need to understand that armoring is a technique to protect the cable and second question will come about the materiel which will be used to protect the cable. It may be fiber yarn, glass yarn & Polyethylene etc. It may be the non metal material.
Now I tell you about the difference between armored and non armored cable
Its very simple that is armored cable will be with extra protection layer cable and non armored cable will be very simple cable that does not have any extra protection material.
Regards
Tam
The difference between and armoured and un-armoured cable is in their outer layers. Armoured cable has additional outer protective layer of steel or aluminium while un-armoured has a PVC or nylon outer sheath.
Armored Cable:
Armored electrical cable contains insulated electrical service wires protected by a flexible steel covering.
Unarmored Cable:
Unarmored electrical cable has no protective flexible steel covering, its covering is made of plastic.
As the name suggests, an armoured cable is protected against mechanical damage, whereas an unarmoured cable is not. Armoured cables are normally underground cables, which can be subject to damage from pieces of rock, etc., which may be in the trench backfill, or from excavation tools.
The 'armour' is a layer of overlapping metal (usually steel) tapes or wires that form the outermost metallic layer of a cable in order to protect the cable's waterproof sheath. This armour layer is itself protected against corrosion with a protective sheath.

What is the difference between pipe and hoses?
Generally a hose is flexible and a pipe is not. I was laying pipe in your girlfriend last night... whereas she and her friends are hose. I hope that helps.
What is the difference between armored cable and flexible metallic conduit?
Armored electrical cable contains insulated electrical service wires protected by a flexible steel covering. Metallic Conduit is a tube or pipe though which we lay electrical cable.(Most commonly lighting cables).
What is the difference between flexible and rigid pavements?
Flexible pavement: Are those pavements which reflect the deformation of subgrade and the subsequent layers to the surface. Rigid pavement: The rigid characteristic of the pavement are associated with rigidity or flexural strength or slab action so the load is distributed over a wide area of subgrade soil.
What temperature does ABS become flexible?
For the majority of applications, ABS can be used between −25 and 60 °C as its mechanical properties vary with temperature, at which it becomes flexible.
What is the difference between armoured car and non amoured car?
The armoured car has armour.
What is a peltast?
A peltast was a light infantryman, unarmoured, equipped with crescent shaped shield and javelins, used to harrass armoured infantry formations and archers, and as well fill the gap between armoured infantry formations and their flanking cavalry. They were mainly hired from the tribesmen of Thrace.

What is the difference between a rigid and flexible endoscope?
one is rigid and the other is flexible :)
What is the difference between a structure that is rigid and one that is flexible?
The difference between a structure that is rigid and one that is flexible is that the rigid structure will not bend or flex when force is applied. A structure that is rigid cannot flex.

Yes, the Presidential motorcade does include armoured vehicles. There are between four and six armoured vehicles in each Presidential motorcade.
What is the difference between a fixed budget and a flexible budget?
is a plan for a single level of production, whereas a flexible budget can be converted to any level of production.
What is the difference between a flexible cord and a flexible cable?
A flexible cord is a flexible cable having a conductor cross section less than =<6mm squared providing a high degree of flexibility for non fixed wiring systems

How did Alexander the Great combine the tactics of the Persians and the Greeks to produce a superior army?
Greek armies were basically foot soldiers, Although armoured infantry who fought in solid formations (the phalanx) were superior to the unarmoured Persians, the latter had the advantage of strong cavalry, so Alexander acquired mercenary cavalry forces. He also added mobile light infantry who filled the gaps and were a link between the phalanx and the cavalry. This topped the Persians who tried to establish their own armoured infantry to match his, but they did not come up to the same standard and failed at the crucial battle of Gaugamela.
What is the difference between strength and hardness?
The difference between strength and hardness is that the strength refers to the force that is present between the bonds. Strength attributes to how strong or weak the force between the bonds. Hardness refers to the nature of the force, which basically is how rigid or flexible the bonds between particles.
