Optical cables for vertical wiring in buildings, which is a major component of the dropsegment in FTTx networks, refer to the drop cables going from ducts in buildings intorooms. Vertical wiring is mainly applied to high-storey buildings, super high-storeybuildings, buildings with high-density subscribers and large information processing centers such as data centers.
