Optical fibers are designed for many different application scenarios. To understand the different applications, it is important to understand the properties of different fiber types.
Two major types of optical fibers exist for communication system: multimode fiber and single mode fiber. The difference between them is that multimode fiber can carry many modes of light rays while single mode fiber can only carry one mode of light ray.
Single mode fiber does have some disadvantages though. The smaller fiber core diameter makes it much harder to couple light into the fiber. This increases the manufacturing cost of many single mode fiber optic components such as isolator, attenuator, etc. Mini Manual Variable Attenuator The tolerances for single mode connectors, mechanical splices are also much more demanding.
One important variety of single mode fiber is polarization maintaining fiber, or also called PM fiber. PM fiber carries only one polarization (the light's electronic field direction) of the light. PM fiber's major applications include coherent communication system and electro-optic modulators which serves as a light transmitter in high speed fiber optic system.

Different types of transformer are audio transformer, fly back transformers,high power transformer,push-pull transformer,current transformer, Electric transformer, Isolation transformer, step up transformer, and step down transformer.
Electric transformer is a device used to transfer an alternating current or voltage from one circuit to another circuit by way of electromagnetic induction. The simplest kind comprises of two coil of wire, insulated from one another and arranged to change the current in one coil would in turn produce a change in voltage in the other coil. A current transformer is a kind of electrical instrument that is produced particularly to provide a flow of current in the secondary circuit that is properly perpendicular to the amount of current flowing in its primary circuit. A high voltage transformer are generally used in power transmission applications, where voltages are very high sufficient to present a safety hazard.
Isolation transformer is a kind of current transformer which is used to supply power for equipments. Isolation transformer was designed specially by the manufacturers to meet the requirements of the business people and general users around the world for affordable prices. Low voltage transformer can be used as a magnetic low voltage transformer or electronic transformer. Low voltage transformers are mainly produced to reduce 120 volt line voltage to the secondary or the output voltage of the 12 volts. Fly back Transformer may be defined as an integrated transformer which implies it has built in rectifiers and divider networks and several low voltage windings.

A fuel cell is an electro chemical energy conversion device, which produces electricity from external supplies of fuel (on the anode side) and oxidant (on the cathode side). These react in the presence of an electrolyte to produce energy.
Welding of the plates is by far the most time consuming process involved in the manufacture of fuel cells - there is about one meter of welding required for every single plate in every single fuel cell stack - that is about 400m of welding for each eco-car. Optimising the welding process offers the opportunity to make significant savings in the cost of production of fuel cells.
The issues here are all related to the difficulty of achieving a small, clean, reliable weld at viable production speeds using traditional laser welding techniques. To solve these problems, the leading-edge manufacturers are now looking to fibre laser welding technology.
Results from leading manufacturers in this field show that fibre laser welding will play a significant role in tipping the balance for fuel cell technology from a 'promising idea' to a serious commercial solution to the world's energy-usage problems.
