ChallengesChallenges
• Cables in the Zorès• Deviation of snake
• Obstruction• Obstacles between
the two coupling heads
• Remaining space
• Network configuration• Height difference between snakes
• Required pushing force

ConclusionsConclusions
� 40…50% fewer holes on streets and pavements
� Construction works represents 50…80% of FTTH Rollout costs
� Less construction works means buildings are connected more quickly
� Optical fibers can be effectively laid in existing pipe networks
