1. Ordinary fiber optic cable

Ordinary optical cables may be the earliest optical cables widely used in communication networks, including commonly used GYTA optical cables (commonly known as "pipeline optical cables"), GYTS optical cables (commonly known as "overhead optical cables"), and GYTA53 optical cables (commonly known as "direct buried optical cables") And GYTZA type optical cable (commonly known as "flame retardant optical cable").

2, FTTH drop cable

The FTTH drop cable is mainly used for the FTTH drop (from the optical fiber distribution box to the user's home ONT equipment), which is divided into ordinary butterfly drop cable (GJXH), self-supporting butterfly drop cable (GJYXFCH), prefabricated end Butterfly drop cable, invisible butterfly cable and prefabricated invisible cable.

3. Optical fiber ribbon cable

Optical fiber ribbon is a thin flat ribbon with 4 to 24 optical fibers arranged in parallel and cured by UV. The optical cable with optical fiber ribbon in the cable is called optical fiber ribbon cable, commonly known as ribbon optical cable.

When a ribbon fiber optic cable with a large core count is spliced ​​by a ribbon fiber fusion splicer, the splicing efficiency of the optic cable can be significantly improved, but the splicing loss is slightly larger than that of the loose fiber optic cable. The optical fiber ribbon cable is suitable for use in the section with a large number of fiber cores in the metropolitan area network and wired access network. Commonly used fiber optic ribbon cables are layered structure (GYDTA) and skeleton structure (GYDGA).
