体が特開昭６１−２７２７０９号に提案された。In addition, it is necessary to partially transmit electric signals for backup purposes to improve the reliability and safety of optical fiber communication. Furthermore, in measurement fields that use optical sensors, the information detected by the optical sensor and the information that controls it may be transmitted separately, and in the latter case it is often more convenient to use electrical signals. It is considered that there are cases in which electrical signals are transmitted in parallel with optical signal transmission using optical fibers, as in the example shown in FIG. Therefore, the simplest method is to arrange a conducting wire in parallel with the optical fiber, but this method requires a complicated configuration of the transmission line. Furthermore, the work required to match the optical fibers and electric wires becomes complicated, resulting in high costs. As a method for improving this, an information transmission medium in which the outer periphery of an optical fiber is coated with a conductive thin film or a conductor core wire is provided in the center of the optical fiber was proposed in Japanese Patent Laid-Open No. 61-272709.

である。Electrical conductors within the optical fiber jacket and/or buffer and/or reinforcement can be used to transmit electrical signals related to optical signals. In addition, since it is possible to provide not only one conductor but many conductors,
It also becomes possible to transmit different electrical signals simultaneously. The shape of the conductive wire in the present invention may be any shape other than a thin film from the point of view of ease of handling, but from the viewpoint of economy, a conductive wire is preferable. The size of the conductor can be selected depending on the thickness of the covering material and/or the reinforcing material, but the diameter is several μm to several cra. The type of conductor is not limited to metals such as copper and aluminum, but it is also possible to use organic substances such as conductive polymers.

際。A primary coating layer, a buffer layer, and a secondary coating layer are formed on the outside of a glass/quartz optical fiber, so when each layer is formed, a conductive wire is inserted at the same time to manufacture an optical fiber.For example, The optical fiber sent out by the sending bobbin passes through an extruder in which a coating material is melted together with the conductive wire, passes through a cooling tank, measures the wire diameter, and winds it up with a winding bobbin. Also, when converting optical fiber into cables.

ある。It is also possible to form an optical fiber transmission body by inserting conductive wires into the cushioning material and twisting them together. In plastic optical fibers, a covering material layer or a reinforcing material layer is formed on the outside of the cladding layer, but when the covering material or reinforcing material is melted and extruded as described above, conductive wires are inserted and molded. Can be done. It is also possible to simultaneously insert an optical fiber and a conductive wire into a heat-shrinkable tube and then shrink the tube while heating to obtain a transmission medium in which the optical fiber and conductive wire are integrated. In this way, the present invention can be applied to both glass/quartz optical fibers and plastic optical fibers.
