Embodiment Construction

[0013] Combine below figure 1 Specific description embodiment:

[0014] A photoelectric hybrid cable, the photoelectric hybrid cable includes several pairs of twisted pairs 1, tight-packed optical fibers 2 and porous plastic filling racks 3, and the twisted pairs 1 and tight-packed optical fibers 2 are arranged on the porous plastic filling rack 3 A total cable core is formed inside, and a PVC or LSZH plastic sheath 4 is extruded on the outside of the total cable core.

[0015] In a preferred manner, the twisted pairs and tight-packed optical fibers are put together into a porous plastic filling frame by twisting.

[0016] Preferably, the tight-packed optical fiber adopts 2-core or 4-core single-mode or multi-mode optical fiber, the outer diameter of the tight-packed optical fiber is 0.9-1.05mm, and the twisted pair 1 includes a twisted-pair conductor 5 and a twisted-pair insulator 6 , The twisted pair conductor specification is 0.500-0.570mm, and the outer diameter of the t...

Abstract

The invention, which belongs to the technical field of a cable tool, especially relates to a hybrid photoelectric cable. The disclosed hybrid photoelectric cable is characterized in that the cable comprises a plurality of pairs of twisted-pair units, tightly packaged fibers, and a porous plastic filling rack. The twisted-pair units and the tightly packaged fibers are arranged in the porous plastic filling rack to form a main cable core; and the outside of the main cable core is extruded with a PVC or LSZH plastic sheath. According to the invention, the cable has the following beneficial effects: hybrid structures of different products are designed differently, so that the transmission efficiency is improved and the size of the overall hybrid cable is reduced; and the transmission bandwidth is increased and can reach 250 MHz and above.

Description

technical field [0001] The invention belongs to the technical field of cable appliances, in particular to a photoelectric hybrid cable. Background technique [0002] The structure of photoelectric composite cable is generally a combination of optical fiber and power line or coaxial and twisted pair. The typical product is a combination of multi-core optical cable with different diameters of power line or coaxial and twisted pair. The conventional twisted pair cable grade is generally Category five. Photoelectric composite cable is suitable for broadband access network system as a transmission line. It is a new type of access method, which integrates optical fiber and power transmission copper wire, and can solve the problems of broadband access, equipment power consumption, and signal transmission. [0003] The performance of the twisted pair in the conventional photoelectric composite cable can only reach the transmission performance of Category 5e, and the composite form ...
