SOGETREL : the major French integrator of urban telecommunications networks Turnover : 200 M€ Employees : 1100 Telecommunication technologies : optical fiber, GSM, Wimax, microwave, Wifi Yearly deployment : Thousands of authorizations negociated > 1000 base stations > 300 microwaves > 100.000 kms optical fiber > 1.000 kms civil work Supplier of all French major private and public telecommunication operators Digiworld Summit 2006 14/11/2006

Key succes factors for a cost-effective FTTH deployment Costs structure Levers to reduce FTTH costs Understanding of existing urban areas Optimized Nodes optical network’s design Optimized ways and lay-in for optical fiber deployment Deployment Roll out Digiworld Summit 2006 14/11/2006

Costs structure of FTTH deployment in % Optical fiber and equipment costs are significant Indoor deployment costs count for a lot * Outdoor deployment costs vary dramatically regarding the kind of process used (from 3 to 1) Digiworld Summit 2006 14/11/2006

Costs structure of FTTH deployment in % Digiworld Summit 2006 14/11/2006

II) Levers to reduce FTTH costs 1) Understanding of existing urban areas The complexity of a urban area from different points of view: TELECOMMUNICATION NETWORKS, BUILDINGS, LEGAL Necessity to consider the whole complexity of the existing area and the specifications of the telecommunication operators to design a new optical fiber acces network Long Haul POP Métropolitan loop Digiworld Summit 2006 14/11/2006

2) Optimized Nodes optical network’s design A balance between the number of nodes, their size, optical fiber cables capacity and diameter, legal constraints. Digiworld Summit 2006 14/11/2006

3) Optimized ways and lay-in for optical fiber deployment Re-use of existing infrastructures Adapted usage of all surface and underground processes to create new infrastructures Digiworld Summit 2006 14/11/2006

4) Deployment Roll out A balance between city life disturbance, authorizations’ extents, early sales, production capacity Digiworld Summit 2006 14/11/2006

SOGETREL : your global partner for telecommunication networks Understands existing urban area Understands telecom operators expectations Understands telecom operators business model Survey Nodes design Ways and lay-in choices Roll out And innovation : Kheops : software for network management Easyfiber ™ Digiworld Summit 2006 14/11/2006

SOGETREL’s innovation : EASY FIBER ™ An innovative way to install optical fiber through no man entry drain systems Digiworld Summit 2006 14/11/2006

An environmental friendly technology TM Eliminate the traffic congestion and disruption, noise, pollution that typically accompanies open-trench cabling construction Cost-effective and faster to operate than traditional trenching techniques Sewers provide a great protective barrier against backhoes Reach virtually every building in a city Non aggressive against the pipes – no drill – no screwing No hydraulic perturbations Small reduction of the cross section An environmental friendly technology Digiworld Summit 2006 14/11/2006

How does it work ? Step 1 Step 2 Step 3 Step 4 Step 5 TM Step 1 High pressure pipe cleaning TV Inspection Recording of the pipe geometry Step 2 Spring steel clips are fixed on a one inch HDPE duct Clips are contracted Duct is introduced into the pipe Step 3 Duct is tended between two manholes Step 4 With a small computer-driven robot, under TV control Duct is positioned on the voute pipe Clips are expanded Duct is tightly fixed to the sewer wall Step 5 Fiber cables are pulled Manholes are equiped with splice boxes Digiworld Summit 2006 14/11/2006
