Passive Optical Network (PON) is a point-to-multipoint optical access technology. It uses only optical fibers to transmit data, voice, and video services. Whether you're deploying, upgrading, or optimizing your network, choosing the right PON SFP module or PON SFP+ transceiver is paramount. PON modules work without needing extra power. This saves energy and lowers repair costs. Operating on a passive optical network architecture, these modules eliminate the need for active. Passive Optical Network, means (in the Optical Distribution Network, ODN ) does not contain any electronic devices and electronic power supplies. In practice, PONs are typically used for the last mile between Internet service providers (ISP) and their customers.
