Transmission Media - 7 Summary on What we have studied on last tutorial  :- Single Mode :  A type of cable that has only single strand of glass fiber with a thin diameter. This is a 9/125 micrometer fiber cable. The diameter of a core glass is approximately 9 micrometer. Multi mode :   A type of cable that contains a glass fiber with a larger diameter. Multiple modes of light signals can be propagated through it. This is 62.5/125 micrometer fiber cable. A connector is a mechanical device that is attached to the fiber optic cable or the light source. Straight tip ( ST) :  It was developed by AT&T. A popular connector used with the fiber optic cables and used in Gigabit Ethernet or backbone. Joins individual fibers to optical devices. Sub Miniature Type A (SMA) :  Defines a connector that uses two individual connectors for each fiber strand. Subscriber/Standard Connector (SC) :  A type of low-cost connector used in 100 Base-FX fibe...
