PON-X® Exploring Future PON

Passive optical network (PON) is a high-speed, cost efficient optical communications technology for delivering broadband network access services. PON optical distribution networks use a single fiber to travel the longer distance from a telecom operator’s central exchange optical line terminal (OLT) to a community of broadband users. A splitter is then used to provide multiple fibers that serve an optical networking unit (ONU) box to an individual home or business.

PON systems are typically used for deployment of high-speed fiber to the home (FTTh) broadband services.

PON systems can also be used for small scale optical home/office networks fibre to the room (FTTr) and as a scalable/cost effective copper LAN replacement in larger offices and campus networks passive optical LAN (POL).

Future Services Enabled by PON Networks

  • Ultra-high definition TV and video on demand
  • Online gaming
  • Augmented reality
  • Smart home
  • Smart office
  • Optical LAN
