FTTH drop cable: it is mainly used for FTTH drop-in section (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), invisible butterfly cable.


Ordinary butterfly drop cable (GJXH) is to place the optical fiber in the center and place two parallel steel wires on both sides as strengthening elements. It is suitable for laying along the wall or through pipes, not hanging in the air.


A self-supporting butterfly drop cable (GJYXFCH) is a non-metallic butterfly drop cable with a reinforcing element (steel wire or steel wire rope) attached to the outside. It is suspended in the air and suitable for introduction from outdoors to indoors.


The invisible butterfly cable (GJIXH) is basically the same as the ordinary butterfly drop cable. The difference is that the middle part of the GJIXH optical cable is a single-core invisible optical cable. It is wrapped with a transparent sheath with a diameter of 0.9mm. The outer diameter is thin and fully transparent. When laying, it generally follows the skirting line of the building and the surrounding of the decorative strips of door and window and is fixed with glue, and the wiring is concealed and beautiful.
