Short Content: Along with communication's swift development, the fiber optic communications technology has become the correspondence the important means. The optical fiber transmission system has the capacity to be big, transmitting range far two big superiority. The optical fiber theory capacity may reach 20000GHz, the non-relay transmission distance may amount to 50-80 kilometers. The light end machine is one kind of equipment which in the fiber optic communications uses, materially is an electrical signal to the light signal, the light signal ...
