HP Optic fiber Cable (234457-B24)

The fiber optic cable provides reliable data interconnect with high speed, over long distances. The fiber channel is actually a gigabit interconnect technology, that allows concurrent communications between devices and peripherals using SCSI and IP protocols. Nowadays, you can see fiber optics in many industries, especially in the computer networks and telecommunications.

Fiber optics are thin and long strands of very pure glass, whose diameter is near about the diameter of a human hair. The fiber optics are arranged in bundles called optical cables which are used for transmission of light signals over long distances. The optical fibers are arranged in bundles in optical cables and their number is in thousands. These bundles are protected by jacket, which is the cable's outer covering.

The optic cable has the following parts:
 Core – this is the thin glass center of the fiber optic where the light travels
 Cladding – this is the outer optical material surrounding the core. It reflects the light back into the core
 Buffer coating – it is plastic coating. It protects the fiber from moisture and damage.
Some optical fibers can also be made from plastic. These plastic fibers have a large core (0.04 inches or 1 mm diameter) and transmit visible red light (wavelength = 650 nm) from LEDs ( light-emitting diodes).
There are two types of optical fibers single module fibers and multi-module fibers.
The Single-mode fibers have small cores (about 3.5 x 10-4 inches or 9 microns in diameter) the single-mode fibers transmit infrared laser light (wavelength = 1,300 to 1,550 nanometers).
The multi-mode fibers have larger cores (about 2.5 x 10-3 inches or 62.5 microns in diameter) and they transmit infrared light (wavelength = 850 to 1,300 nm) from LEDs (light-emitting diodes).

The optic fiber cables provide more benefits as Compared to conventional copper wire (metal wire).
The optical fibers are more advantageous as compared to the copper wire. The optic fibers are:
 Suitable for Digital signals
The optical fibers are ideally suited for carrying digital signals.
 Non-flammable
There is no threat of fire, because electricity is not used.
 More Thinner
The optical fibers can be drawn to smaller diameters as compared to the metal wire.
 Low cost
The optical cable is cheaper than copper wire.
 Less signal degradation
The loss of signal in optical fiber is less than in copper wire.
 More capacity to carry
As the optical fibers are thinner than copper wires, therefore, more fibers can be bundled into a given-diameter cable than copper wires. In this way more phone lines go over the same cable or more channels to come through the cable into your cable TV box.
 Lightweight
The weight is less than the copper wire cable. It also uses less space in the ground.
 Low power
Lower-power transmitters can be used instead of the high-voltage electrical transmitters needed for copper wires.
 Light signals
The light signals in the optic fiber do not interfere with those of other fibers in the same cable. Due to the absence of interference the phone conversations and the TV reception become clearer.
