ITU-T G.983

ITU-T G.983 is a standard that defines how fiber optic communication systems, specifically Passive Optical Networks (PONs), should operate. It ensures compatibility between equipment, specifying details like signal formats, transmission methods, and system performance, to enable reliable high-speed internet and data services over fiber optic cables. Essentially, it provides guidelines for building and maintaining efficient, interoperable fiber networks used by internet providers and other communications services.
