The embodiment of the application discloses a pipeline optical cable.

Referring to fig. 1, a pipeline optical cable provided in the embodiment of the present application includes a plurality of optical fiber sets 1, an electromagnetic reinforced core 2, a cable core substrate 3, and an outer sheath 4; a plurality of optical fiber groups 1 are uniformly distributed around the circumference of the electromagnetic reinforced core 2; each optical fiber group 1 and the electromagnetic reinforced core 2 are arranged in the cable core matrix 3; the outer sheath 4 is arranged outside the cable core substrate 3.

Particularly, the electromagnetic reinforcing core 2 has electromagnetic characteristics, so that the optical cable is conveniently searched, and the transmission function of the optical cable cannot be influenced.

As a further improvement, the electromagnetic strengthening core 2 is specifically made by adding 20% -40% of iron powder core into the optical cable core.

Specifically, substances having electromagnetic properties are classified into diamagnetic, paramagnetic, ferromagnetic, antiferromagnetic, and ferrimagnetic substances according to their internal structures and properties in an external magnetic field. Ferromagnetic and ferrimagnetic substances are ferromagnetic substances; the diamagnetic and paramagnetic substances are weakly magnetic substances. The iron powder core is a weak magnetic substance with paramagnetism, has inherent magnetic moment which is not zero, and in the absence of an external magnetic field, the orientation of molecular magnetic moment is randomly distributed due to thermal motion, so that the iron powder core does not show specific magnetism macroscopically. In this embodiment, the iron powder core is added to the optical cable core, so that the prior transmission of the optical cable is not influenced, and meanwhile, when the optical cable is searched, the optical cable can be quickly positioned by utilizing the electromagnetic property of the iron powder core. Preferably, the content of the iron powder core in the electromagnetic reinforcing core is 20%.
