Why FTTH is neededPortugal Telecom use case

Exponential demand for bandwidth and integrated 3P services requires a future-proof network evolution pathNew services require increased bandwidth … that only FTTH will provide in long term

•Lower OPEX with reduced energy consumption (4 to 5 times less)•Less space required, with equipment 4 to 6 times more concentrated•Better quality of service with loss down time

•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 term, with NGPON)



FTTH network supports the aggregation of different traffic types:

The Future of FTTH

Conclusions

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)

FTTH in Portugal

RF Overlay network designed to maximize use of remote Head End ODN Network uses two or three(2x2@CO) stage splitting

Conclusions

The Future of FTTH

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

an opportunity to

grow in terms of

revenues and

regaining clients

NG-PON2

standards are

critical to allow

network growth

over existing ODN,

to target new
