Building cabling for FTTH

Since 1st of April 2012 : in France it is mandatory to pre cable the building backbone with fibre (FTTH)

French cabling standard XP C 90-486 and ETSI TS 101 573 (Telecom risers) : • Installation of Floor Distribution Box • Installation of Optical ENTI

Easy mid span access riser cables

– Only fibres are extracted from the cable and managed in the distribution/branching point (to be spliced with fibres of the branching cable)

– Fibres to extract are cut in the upper branching point and pulled at the considered branching point: cable with a specific structure to extract fibres over a few meters

Access to fibres and management of fibres in the

DP with a classical cable

Access to fibres and management of fibres in

Building and in-home optical cabling

Solutions to reduce the implementation time and improve the acceptance of the wiring by the customers

Mixed copper & optical outlet to replace an existing copper outlet

Optical ENTI with a design optimized for installation in a home distributor

Small low friction cables for installation by 1 technician into conduits (free or already occupied by a cable)

Optical cable connectorized to an outlet with a cable unroller

Plug & Play kit with 30m of invisible fiber for in-home wiring

Easy mid-span access riser cables used in the common parts of the building

Standard cable 3 mm

Standard cable Easy mid-span cable

900µm fiber

Flexible flat head (patented by Orange) to pass corners and avoid the twist of the optical cable around the existing cable

Low friction optical cable 2,7x1,9mm

Coaxial cable 7mm

Interne Orange 15

Apparent installation on the wall – Refusal from some customers because of aesthetic reasons New solution for a more aesthetic cabling

900µm cable connectorized at both sides Optical outlet with a wiring system to manage the overlength of cable Accessories to ensure a minimum bending radius in the corners and accessories to

pass through the walls
