What is Active Optical Network (AON)?
Home run (AON)
– Point to point
– Highest bandwidth
– High flexibility
– Most deployed in Europe
Active star (AON)
– High bandwidth
– High flexibility
– Active equipment in field
– Most deployed in Europeand Korea
Passive optical network (PON)
–Passive network with
tree topology
–Average bandwidth
–Most deployed in Asia andUSA

What determines NGOA?
OPEX
CAPEX
Digging costs
Business model
Regulation
Traffic pattern
Technical performance
Political & societal factors
• Mutually more or
less contradictory
• Different for AON
and PON
There will not be one size fits all, but we
need to understand the differences and
similarities for the various solutions

Topology Trends in NGOA
NG PON approach:
Many COs are costly in
OPEX ->
Consolidation of COs
NG AON approach:
Contents become local ->
Dynamics in distribution

Today PON and AON
topologies very similar

Measurements on a Swedish FTTH network
(Jan–June 2010, 2500 users), symmetric
The success of peer-to-peer technologies:
Illegal file sharing: Pirate Bay, etc
Commercial content distribution: Spotify, Voddler, NRK, etc
File sharing reduces server costs and optimises content distribution
Key question: How much traffic is local?

Future options for AON
Mesh-like AON/Ethernet for higher dynamics and flexibility
the access and distribution networks can be merged
Inherently higher resilience without adding cost to network elements (NE)
The possibility of keeping local traffic local e.g. for P2P based content distribution

Conclusions
Many factors determine the shaping of NGOA – the are often
mutually contradictory
Two topology trends today: Dynamics in distribution network vs
consolidation of central offices
Traffic in high capacity access networks dominated by peer-to-
peer traffic
NG AON merges access and distribution into one multi-layer
network
Provisioning across home gateway demonstrated in
interconnected home/access network
There will not be one size fits all, but we
need to understand the differences and
similarities for the various solutions
