Fusion Splicing. Fusion splicing is the process of fusing or welding two fibers together usually by an electric arc. Fusion splicing is the most widely used method of splicing as it provides for the lowest loss and least reflectance, as well as providing the strongest and most reliable joint between two fibers. Virtually all singlemode splices are fusion.
Disc Brakes. A disc brake system consists of a brake disc, a brake calliper and brake pads. When the brake pedal is applied, pressurised hydraulic fluid squeezes the brake pad friction material against the surface of the rotating brake disc. The result of this contact produces friction which enables the vehicle to slow down or stop.
A brake rotor is a smooth metal disc attached to the wheel hub. Most new cars (1999 and above) come with rotors at each wheel. Older cars may have drums instead of rotors at the rear wheels . Brake rotors play an important part in the braking system. It is the friction between brake pads and rotors that cause your car to slow down and stop.
