Motivations for PON deployment
Fiber saving between splitter and CO/POP
relevant in scenarios where existing cables or ducts need to be reused towards
the splitter, or where fiber deployment is restricted (e.g., aerial cabling)
Less relevant for Greenfield scenarios
(marginal cost of fiber compared to digging, splicing, ...)
Analog video overlay for existing broadcast services
emulates cable TV distribution plant on a separate downstream
wavelength delaying introduction of IP TV
requires equivalent of cable headend at each OLT side
Port saving in the CO/POP
need to terminate thousands of fibers on switch ports
PON can reduce this by 1...2 orders of magnitude compared to P2P
port costs on a per-customer base, however, are roughly equivalent
No deployment of active equipment in the outside plant
in Europe & Middle East typically loops are sufficiently short
so that P2P deployments do not require active equipment in the outside plants
