PON TECHNOLOGIES

Passive optical networks<nbsp;(Passive Optical Network, PON) represent one of the most important directions in the deployment of optical access networks. Passive because there is no need to use actively operated network elements between the ISP's switching point and the end customer.</nbsp;(

A significant advantage is the lower construction and operating costs compared to active networks. Passive networks save both the number of fibres pulled (sharing of the transmission width of a fibre by several subscribers) and the equipment required for network operation (simplification of the network elements in the provider's exchange).

PON technology provides access to advanced "triple play" services, i.e. internet, television and voice services. The GPON standard for passive optical networks enables transmission speeds of 2.4 or 1.25 Gb/s per user using WDM, i.e. the transmission of signals in a single fibre with different wavelengths. New generations of NG-PON enable 10 Gb/s , 50Gb/s and even 100Gb/s.
