GPON or 'Gigabit Passive Optical Networks' is a point-to-multipoint access mechanism. The main characteristic of GPON is the use of passive splitters which enable a single feeding fibre from the network provider's central location to serve multiple users within their homes and small businesses.

What is passive in GPON?

Passive Optical Network (PON) which had no active components between CO and customer. Passive equipment has no electrical power needs, it guides the traffic signals contained within specific optical wavelengths. ... And particular equipment used is GPON – GPON equipment.

Is GPON single mode or multimode?

GPON uses optical wavelength division multiplexing (WDM) so a single fiber can be used for both downstream and upstream data. A laser on a wavelength (λ) of 1490 nm transmits downstream data.
