With the rapid development of the telecom industry and increasingly specified market demand

the traditional structure

manufacturing technique

and installation method of fiber optic cables are no longer consistent with the increasingly saturated and limited pipeline resource. Therefore

fiber optic cables with large fiber count

small outer diameter（OD）

and simple installation method

which satisfy the new market demand

have become more and more popular among users. This article mainly introduces a new type of optical fiber cable structure under the requirement of large fiber count and small cross-sectional area. The article also analyzes the structural characteristics

performance characteristics

manufacturing technique and application prospects to serve as a reference for the research

design

manufacture

and application personnel of fiber optic cables.
