Fiber Optic Cabling
Imagine a strand of optically pure glass as thin as a human hair being able to carry digital information for miles and miles. It’s true, Cabling Hub has the technology. A single optical fiber has a thin glass center where light travels. Covering the glass is an outer optical material that surrounds the inner core and reflects the light back into the core. On the exterior of the wire, there is a buffer coat to protect the fragile fiber from moisture and damage.
Fiber optic cabling transmits light through the fiber and functions as a waveguide, or “light pipe.” This type of wire is used for communication links where high power must be transmitted and is more complex than electrical wire or cable. A major benefit of fiber optic cabling is that it is immune to electromagnetic interference and is specially designed for higher bandwidths (data rates) than other types of cables.
There are two types of fiber optic cabling and the main difference between the two cables is the core diameter.; single-mode fibers and multi-mode fibers. Single-mode fibers transmit infrared laser light through a smaller core. Multi-mode fibers transmit infrared light produced from light-emitting diodes (LEDs) and have a larger core. The optical fibers are ideal as a medium for telecommunication and computer networking because they are flexible and can be bundled together.
The light in fiber optic cabling is constantly bouncing or reflecting from the cladding within the wire, or mirror-lined walls. This causes the light to travel freely through the core because the cladding does not absorb any of the cores light. Without interruption, the light wave in the cable can travel great distances.
This intricate type of cable is perfect for applications like the Internet, telephone systems and cable TV, transmitting data. In order for the cable transmission to complete, it needs to be connected to the other main components in a fiber optic system. A fiber optic system consists of the following:
Optical fiber cabling- Conducts the light signals over a distance
Transmitter – Produces and encodes light signals
Optical regenerator – May be necessary to boost the light signal (for long distances)
Optical receiver – Receives and decodes light signals
The transmitter generates a light signal by receiving and directing the optical device to turn the light on and off in the correct sequence. It is physically close to the fiber optic cabling and may even focus the light into the fiber with a lens.
An optical regenerator can be spliced along the cable to boost any degraded signals of light by emitting a new, stronger light signal with the same characteristics as the incoming weak light signal. Optical receivers are the ultimate destination for the light in the system. The receiver decodes the signal using a photocell or photodiode and sends the electrical signal to the other user’s computer, TV or telephone.
Fiber optic cables are becoming more common because they meet the needs of even the most demanding data communications, voice and video networks. While more expensive than other types of cables, they are increasingly being used instead of traditional copper cables due to the fact that they offer more ultra high speed Internet capacity and are less susceptible to electrical interference.
Use of fiber optic cabling to connect central offices and long distance switches has thousands of times the bandwidth of copper wire and can carry signals hundreds of times further before needing a repeater. Fiber gives greater reliability in an industrial environment because electromagnetic interference (EMI) is often a big problem.
Industrial equipment, like motors, relays and welders, generate a tremendous amount of electrical noise that can be the source of problems with copper cabling, especially with unshielded cable like Cat 5. It is commonly necessary to pull copper cable through conduit to provide adequate shielding in these environments. However, fiber optic cabling can provide complete immunity to EMI and can be installed easily from point to point, passing right next to major sources of EMI with no effect.
Copper networks can easily be converted with media converters, or gadgets that change most types of systems to fiber optics. Fiber optic networks will be less than copper run in conduit, even with the cost of the media converters. When it comes to cost, looking at the cabling component prices may not be a good way to analyze total network expenses. Instead, consider the total system and you may find fiber looks a lot more attractive.
