Nexans 2012 1 Extraction Principle Cable 2 Extract

Extraction Principle Cable 2. Extract the nanocable for routing 1. Cut of the extractable nanocable at upstream location © Nexans 2012 - 2

Extraction Principle Are these Nano. Cables lost ? No Fibres to connect the Nano. Cables from the other side Splicing box © Nexans 2012 - 3

Extraction Principle 2. Extract the nanocable for routing 1. Cut of the extractable nanocable at upstream location 3. Second extraction of the nanocable © Nexans 2012 - 4

Aerial Cable Jelly Fibres Tubes FRP ADSS cable Aramid yarns Cable Short pullback Cable with two parts: ● Primary Distribution Cable (ADSS Design) ● Secondary Distribution Cable © Nexans 2012 - 7

Nexans aerial solution Power cable FO Feeder & Distribution cable 12 Customer Connections Aerial Box for 12 splices l l 12 Customer Connections One cable deployment No need to make regular omega loops Single fiber management solution No risk to disturb the main communication Cable Aerial Subscriber box © Nexans 2012 - 8

Omega Connection l l This operation is done regularly based on the subscriber potential One tube with 12 fibers is spliced to the secondary distribution Cable © Nexans 2012 - 9

Fibre Extraction Principle Protection Box and Boxthe closure and cut protection On subscriber extraction phase: Cut to access thebackbone distribution Cable No action on the cable © Nexans 2012 - 10

Customer Connection Primary Distribution cable Suspension piece Extraction of fiber(s) ~1, 5 m Small Box for closing secondary cable where fibers has been cut for extraction Secondary Distribution cable with 6 / 8 /12 individual fibres Drop cables to customer Max 12 Customer connection box with splices or connectors Pole © Nexans 2012 - 11

Conclusion Ø Reduced TCO approach Extractable/ADSS Savings 0 5 10 15 20 0% -5% -62% -10% -15% -20% -25% -30% 2 -8% 4 -17% 8 -27% -35% -40% l l l Customer/Km 16 -38% The cable design is more expensive, however, Based on a 8 km deployment with a customer density of 2 subscriber /km There is already a global cost decrease of 8% Optimization depending on the network mapping and decrease with higher density Ø Security of subscriber connection without disturbing the main link Ø No damage to the tension structure Ø Improvement: Possibility to develop a box containing both the cable openings. © Nexans 2012 - 12

Conclusion l Pullback solutions provide q Easier Cable deployment, q Reduced impact on the transmission network, when connecting a new subscriber q Easier repair possibility (rapid, no additional splice along the way) q Reduced TCO, based on R&D recommendations q Is part of the KINOPTIC solutions combining Cables and Components. © Nexans 2012 - 13
