The loose tube is as follows: optical fibers can be loosely placed in the cable, and a sleeve made of polybutylene terephthalate (PBT) protects the optical fibers from internal stress and external side pressure. Even the optical cable with the same purpose is characterized in that the optical cables are different in number of the optical fibers, the optical cables are small in appearance difference and low in identification degree, and when the optical cable is used, two different optical cables are easily mixed, so that inconvenience is caused.

In the prior art, although the ferrule body is also distinguished by being arranged in different colors, when the number of optical fibers reaches a certain number, the ferrule body is also difficult to clearly distinguish by the different colors of the ferrule body.
