ONT – Optical Line Terminal, located at the customer/subscribers location, converts the optical media being sent by the OLT. From an architectural standpoint, fiber-optic communication systems can be classified into two. These strands, known as fibre optic cables, have revolutionised telecommunications because they transmit information using pulses of light. The light is a form of carrier wave that is modulated to carry information. Fiber is preferred. Multichannel erbium doped fiber amplifiers (EDFAs) @ 1550 nm deployed. This tutorial explores the essential aspects of FTTH, including network architecture, configuration and the various technologies involved, such as AON, PON, EPON, and GPON.
