Why FTTH is needed
Portugal Telecom use case
Exponential demand for bandwidth and
integrated 3P services requires a future-proof
network evolution path
New services require increased bandwidth … that only
FTTH will provide in long term

•Lower CAPEX with reductions of 30%
to 60%
•Less OPEX with reduced energy
consumption (~2,5 time less)
•Less space required, with equipment
~7 times more concentrated
•Potential to increase bandwidth with
lower split ration (and in the medium 7
term, with NGPON)
Why FTTH is needed
Portugal Telecom use case
FTTH network supports the aggregation
of different traffic types:
Residential (IPTV, HSI, VoIP)
Corporate/Soho (Different Services Classes)
Mobile Backhaul (UMTS, LTE)

FTTH in Portugal
In the PT case, each PON, in a B+ class
GPON, supports 64 ONTs that are acquired
by the use of two or three levels of
splitting .
Typical distance <20km.
RF Overlay carries up 70 PAL B/G TV
channels
• 2.5 Gbps downstream
• 1.25 Gbps upstream
• B+ class GPON (28dB)

NG-PON2 Requirement for coexistence with RF Overlay in
GPON scenario:
•
Support of RF Overlay is needed;
•
Minimize impact on the RF performance;
•
Upgrade to NG-PON with minimal service disruption of GPON
clients;
Increase the bandwidth to ≥10 Gb/s DS & US, ie NG-PON2

Conclusions and
Recommendations
FTTH provided PT
NG-PON2
an opportunity to
standards are
grow in terms of
critical to allow
revenues and
network growth
regaining clients
over existing ODN,
to target new
business services
