Copper network in Italy: LLU Success Story

The Unbundling model used with the classical copper access network has been a case of great success in opening the access network and has allowed great development of competition and created great advantages for the consumers.

Copper Network is unique as:

Why not FTTH?

Fiber optic unbundling in FTTH

Point to point architecture, one fiber for user from the exchange to the home. The fiber optic unbundling can be provided at the exchange side.Solution is similar to copper unbundling.

A Future Proof Network

Maximum flexibility and ease in passing from one operator to another

Technology agnostic (the access network is single passive fibre that can support any technology such as ethernet, GPON, etc.)

Symmetric services

Zero touch: no further infrastructure up-grade

Low maintenance cost

P2P Architecture

- -

P2P needs a lot of fibers but:

New micro-cables technologies allow higher existing infrastructure reuse (not only Telco)

New digging technique make easier new infrastructure development (micro trench, one day dig…)

P2P needs space in Central office but:

New High density Optical Distribution Frame allows to manage up to 10k fibers in about 30-40 m2

No need of thousands of cabinets installed in curb or building

High Density Optical Distribution Frames are becoming available

For example :

Application Footprint: max. 1536-ports/frameApplication Density: max. 3353-ports/m²

New technologies in support to Fibre Implementation

In Rome we are testing jointly with Fastweb and Vodafone an Optical distribution Frame for 10k fiber with 36m2 footprint in an LLU scenario

FTTH has long term viability

Pay back investment not less than 7-10 years

Crucial issue for credible business model is Copper Total Replacement.

Copper fees totally transferred to the fiber network.

Other solutions for enhancing the FTTH business model can be found by introducing new broadband services and by decreasing the cost per home passed (100% take rate)

FTTH Business Issues

FTTH Business Issues

Many studies show that one P2P infrastructure can optimize the global investment and the TCO

The total amount of available money is limited. Instead of overlapping several networks, the overall coverage could be enlarged with a single network, using the same amount of money

Overlapping NO-Overlapping

FTTH Business Caseand ImplicationsFTTH Business Caseand Implications

Pure P2P cost VS Multi-GPON

Memorandum Of Understanding Italia Digitale Sviluppo dell’infrastruttura per Reti a Banda Ultra LargaRoma, 10 novembre 2010

A MOU has been undersigned between Operators and the Government who has promoted it , in order to stimulate the development of Ultra Broad band Networks in Italy.

From the evaluations carried out within the MOU, it can be deduced that the additional capex needed to implement a fully P2P architecture would be around 10% vs multi-GPON

- -

Average Capex difference between Base Case (Std GPON) and Exchange Flexi Point(1 fiber per user from the Exchange to the Household, PtP like) is about 23%

P2P +23% vs Single GPON, but Multi-GPON +47% vs P2P

P2P represents a viable solution in high take rate area and small to medium CO

The opportunity is to build only one fiber agnostic infrastructure(P2P) with copper total replacement in order to:

Avoid duplication

Enlarge as much as possible FTTH area

Enable services ecosystem and Country economy

Reduce TCO and guarantee future profness

Infrastructure could be a premium only in start-up phase

Lesson Learned in Mobile Tower is clear: now each operator tries to share sites as much as possible
