GPON – Gigabit Passive Optical Networking
This technology allows extended Ethernet connectivity over fibre-optic cabling infrastructure over distances up to 40Kms.
GPON technology is primarily designed to provide Point-to-Multipoint connections with line rates up to 2.5Gbps in the downstream direction and 1.25Gbps in the upstream to both commercial and residential Customers.
Passive Optical Splitters
The fibre-optic cabling infrastructure for GPON systems includes Passive Optical Splitters which enable single fibre-optic cables to ‘fan-out’ to multiple fibre-optic cables by ‘splitting’ the available GPON light spectra.
GPON Splitters are available in 1×2, 1×4, 1×8, 1×16, 1×32 and 1×64 formats, offering up to 64 splits from a single fibre-optic ‘uplink’.
GPON Splitters can also have multiple uplinks for redundancy e.g. 2×32
GPON splitters can also be ‘daisy-chained’ to expand the fibre-optic line plant even further if so required. Note; Light power budgets (db) need to be calculated to determine how many GPON Splitters in total can be added in series.
