【Abstract】 FTTH has got deeper and deeper penetration in recent years. Based on the economy and speed of the FTTH construction the installation methods of FTTH fiber optic cables have different features from those of trunk fiber optic cables,such as miniature structure,high density of fibers,easy mid-span access,and dry cable core. In addition some connection technologies are adopted,such as mechanical connection,field installable connector,and preterminated connection. The configuration and requirements for fiber optic cables used in FTTH are presented,and the structures,characteristics,and field installation technologies of the new types of fiber optic cables used in FTTH are described.更多还原
