Optical Transmitters drives the Technology behind the Fibre Optic Cable communications

Modern day communication relies a lot on the fibre optic cable connections. The system includes a series of cables made of fibre optic channels connected to optical transmitter. Amplifier system may also be used to magnify the weak signals in case multi-modal fibre optic cables. For domestic applications, the multiple fibre optic cables are routed through the underground conduits and tubes to ensure minimum interaction with environmental factors and human contacts.

 

Optical Transmitters: The Heart of Technology
The optical transmitters used in the fibre optic cable system are made of semiconductors. The Light-emitting Diodes or LEDs and Laser diodes are the most common optical transmitters used in the modern communication models.  The optical transmitters that have LED source produce an incoherent light beam, while the ones installed with Laser Diodes produce a beam of coherent light source.

What are the properties of a good Optical Transmitter?
For the sake of compatibility with the modern day Fibre optic cable system, the Optical transmitters must be:
-    Compact in design to accommodate large bundles of fibre optic cables
-    Efficient in terms of power consumption
-    Minimum interference with the external signal sources
-    No loss of signal due to heat dissipation
-    Reliable accuracy owing to good quality insulation
The Laser diodes used in the Fibre optic cables are more affordable and reliable in terms of their operational benefits over a wide range of wavelengths and high frequencies. In case of optic channels using the LEDs, the efficiency is ambiguous and hard to predict. LED optical transmitters should be used to reduce cost and not for high-performance applications.

The reduced dependence on the Amplifiers
In a traditional fibre optic cable layout, there could be multiple nodes where amplifiers can be linked. A sequential cable router can have as many as a 10 to 15 amplifiers. The information passed through the fibre optic cable layout is typically encrypted digitally that can be generated using the same set of hardware used in computer, telephone systems and telecom models.
Another advantage of using Laser-based transmitters is the minimized dependence on the optical receivers and amplifiers. The primary photo-dectors for telecommunications are made of conventional photo-diodes with Metal-semiconductor-Metal configuration.

What is the modern LED optical transmitter trend?
LED Optical transmitters are made of Gallium arsenide or Indium Gallium arsenide phosphate. Fibre optic cables used with the LED based optical transmitters can carry a longer wavelength of signals. Despite their high fibre dispersion rate, these transmitters can be used with quantum wells to emit signals over a broader spectrum.

All local area Wavelength- Division Multiplexing networks use fibre optic cables installed with LED-based optical transmitters.

The LEDs are quickly getting replaced by the Vertical Cavity Surface Emitting (VCSEL) Lasers. Speed is the key to transmit signals through the fibre optic cables. VCSEL devices are compatible with all single-mode as well as Multi-mode optic cables.
From stability to high-grade circuit integration, optical transmitters are major components of the optic fibre telecommunication channels.

Fibre Optic cables: 6 Reasons why it is the Key to Power and Data Transmission

Copper wires have ruled for more than two centuries. Now it is time to phase them out with a more efficient and power saving option. The recent technological demands summed up as data requirements have thrown up a novel item. The fibre optic wires used in the transmission of electrical signals and data are doubling up the digital inventions made every year.

The 6 things about the fibre optic cables and connectors that make them unique are as follows:

1    Abundant Raw Material
Optic fibre cables are made using sand. The silica is the basic raw material used to manufacture the high grade optic cables. Cheaper versions do use the plastic materials but for transmitting power and data over a long distance, silica is the best material. The silica is processed from sands from the river banks and sea shores.
Other compounds being explored as a potential raw materials are:
-    Fluoroaluminate
-    Chalcogenide
-    Fluorozirconate

2    Simple classification
The fibre optic cables are classified as Single mode cable and multimode cables. The wires with diameters less than 10 microns are placed in the segment of Single mode fibre optic cables.
The multi mode cables have a diameter between 100 and 50 microns.
A special set of plastic fibre optics are also included in the family of optic wires. They are referred to as POFs.

3    It works much like your Camera Lens
The fibre optic cables works on the principle of Total Internal Reflection and the signals are transmitted based on Optical properties. The higher the quality of glass material used in the fibre optic cables, higher will be the efficiency in data transmission. The light pulses bounce multiple times from the internal walls without losing the energy. It follows the Law of Conservation of Energy and Charge.

4    It does not get Hot
Industrial sectors can finally breathe a sigh of relief. The fibre optic cables come as welcome solution to fight global warming and heat dissipation issues. The carbon rating from the fibre optic cables is least and it hardly gets hot. It means that the fibre optics can be used to transmit charge infinitely without losing its efficiency over a period of time due to conduction or radiation.

5    Safe to Touch even when it is transmitting
Electrical shocks remain the biggest fear in the minds of the user while handling electrical appliances. The fibre optic cables minimize the risk to a certain degree. The insulation and the internal optical properties of the fibre optic cables make the wires easy to handle and install even when they are connected to the source.

6    No change in efficiency even when it’s bent or twisted
Physical properties are not affected due to twisting or bending of the wire. It continues to carry signals as per its original rating. With no issue of broken fibres or blocked channels, the user can continue to experience highest performance from the appliances even in restricted space.

Optic Fibre: The Drive behind the Digital Revolution

The space could be expanding, but the technologies on Earth are shrinking every second. The contracting medium with invisible potential to meet daily needs is driven by the fibre optic cables and the semiconductors. The optic fibre cables have been successful introduced in commercial as well as in high-end domestic units with ease. While the industries transform into seamless platforms, it’s the common consumers at home who can benefit much more from using the appliances compatible with the sleek fibre optic cables. The cables can emphatically replace the existing metal wires and hence qualify as the tools of evolution in electronics and electrical segment.

Here’s a list of things you must know about the optic cable fibres that make them compatible with existing wiring systems.

Looking for High Bandwidth: Fibre Optics is the Solution
 

The fibre optic cables have been projected as the simplified tools of network layout. The cables can be used to transfer data across a reasonably larger distance at high bandwidth capacity. It automatically translates into better speed and higher quality of data transfer. The glass fibres ensure minimal interference with the localized magnetic and electric fields. Systems using fibre optic cables experience fewer cross-signal interference and minimum data corruption.


Everything will work at the Speed of Light

Since ages, scientists have been trying to build electrical systems that can match the efficiency of photons and light pulses. When an object travels with a speed close to that of light, it experiences minimum resistance from the medium. Unlike the metal wire cables, the working of the fibre optic cables is independent of the properties of material or quality. If glass is used, the fibre optic cables qualify as a standard light pulses carrier. It means the industry saves material cost and quality testing time to verify the efficiency of the external coating of insulation used in copper wires. Customers can enjoy every appliance working at speed close to light pulses.


It’s time to say goodbyes to electrical failures

The electrical systems using the standard fibre optic cables have shown tremendous efficiency in sustaining fluctuating power loads. The resistance to electrical failures make these wire cables a suitable option for use as Power Transmission and Management element. Imagine the millions of dollars that can be saved by using few kilometres of optic cables that neither breaks or surge under environmental pressure?

 

Building a Hybrid system with Existing wires

Certain operations require the use of copper wires even today. Like fuse wire or grounding circuits. Even the submerged transformers and motors operate with copper wires. The fibre optic cable can be used harmoniously with the wired systems. The cost of expansion or evolution can be saved by simply integrating the new wires with the older hardware and peripheral accessories.


Easy Troubleshooting

The fallouts in system using the fibre optic cable can be easily detected and resolved using spectrometers. The troubleshooting of failure in conventional metal wire layouts take longer time as far as detection and replacement is concerned. With fibre optic cables, the troubleshooting time is reduced by over 400 percent. The cost of replacement is exponentially downsized too!
