The optical cables used in FTTH networks are divided into outdoor optical cables, indoor optical cables, and indoor outdoor optical systems according to their working environment. According to the position of light in the FTTH network, it is divided into feeder fiber optic cables, distribution fiber optic cables, and incoming fiber optic cables.

1. FTTH Outdoor Drop Cable requirements

The optical cables used in the FTTH network are divided into outdoor optical cables, indoor optical cables, and indoor outdoor optical cables according to the working environment. They are divided into feeder optical cables, distribution optical cables, and indoor optical cables according to the position of light in the FTTH network.

2. Indoor optical cable requirements

Indoor optical cables used for FTTH are usually divided into single core optical cables, dual core optical cables, multi-core optical cables, and fiber ribbon optical cables. In addition, according to different purposes, it can be divided into vertical wiring optical cables, horizontal wiring optical cables, and equipment interconnection optical cables. Under long-term allowable tension, the strain of the optical fiber should not exceed 0.2%, and there should be no obvious additional attenuation of the optical fiber. Under short-term tension, the strain of the optical fiber should not exceed 0.4%, and there should be no obvious residual additional attenuation. The sheath should have no visible cracking.
