Abstract

This invention discloses a type of optical cable wiring system, including: a main optical cable, first optical cable connector box and optical cable fan-out disposed near a first user zone; a second optical cable connector box disposed at a distance from the first user zone and near a second user zone; and a single main adapter optical cable disposed between the first optical cable connector box and second optical cable connector box. An optical cable fan-out converts a single main adapter optical cable to multiple branch adapter optical cables. Multiple branch adapter optical cables are connected to the main optical cable via a first optical cable connector box; multiple first distribution optical cables for the purpose of connection to a first user zone are connected to a main optical cable via a first optical cable connector box; multiple first distribution optical cables for the purpose of connection to a second user zone are connected to a single main adapter optical cable via a second optical cable connector box. In this manner, it becomes unnecessary to lay multiple second distribution optical cables over long distances between the first user zone and second user zone, thus reducing the laying length of second distribution optical cables, reducing material and labor costs, and additionally improving municipal aesthetics.
