types of fibre
Different Types of Optical Fibres. In optical fibre technology, multimode fibre is optical fibre that is designed to carry more than one signal at a time. Each carries multiple rays or modes concurrently, each at a slightly different reflection angle with the optical fibre core.
Type IIa fibers are also sometimes known as fast oxidative fibres and are a hybrid of type I and II fibers. These fibers contain a large number of mitochondria and Myoglobin, hence their red colour.
Single mode fibre is optical fibre that is designed to carry a single signal at a time. It is used mainly for long distance signal transmission. A: STEP-INDEX MULTIMODE FIBRE has a large core, up to 100 microns in diameter. As a result, some of the light rays that make up the digital pulse may travel a direct route, whereas others zigzag as they bounce off the cladding.
