There are many different types of fibre cable but for this report I will be explaining the most common type, which is 62.5/125-micron loose tube. The numbers on the diagram represent the diameters of the fibre core and the cladding, these are measured in microns (millionths of a metre). The loose tube fibre cable can be used indoor or out door a gel, which acts as a moisture barrier, normally surrounds the outdoor cabling. The number of cores in one cable can range from 4 to 144. The 62.5/125 microns is a multimode cable and as stated before are the most common cables used, although recently the 62.5 has become more popular. As you can see in the diagram (Refer to Appendix) an outer sheath covers the fibres, this is normally plastic and protects the fibres from physical damage. The cladding that surrounds the fibres is a reflective coating and “acts as a mirror that bounces light waves back into the fibre core. (Burd, 2001, 296)”
