This document is effective when optical cabling in a building is shared with multiple optical access operators. The figure below shows a schematic representation of what could exist in a building with multiple operators' FTTH access networks, without shared cabling.

Many cables and boxes could be installed in common parts in this assumption which can cause permanent disturbance for inhabitants. Besides, saturation of infrastructures could be reached with a strong impact on reliability of existing and new cables and on maintenance issues.

A challenge for operators in that case could be to try to provide the condition for optical cabling sharing inside the building.
