Embodiment 1
[0026] please see Figure 1 to Figure 3, an optical cable with a coaxial electrical unit, which is composed of a cable core, a shielding layer 12 covering the cable core, and an outer sheath 13 that is extruded and coated outside the shielding layer. The cable core is composed of the inner layer of the cable core and the outer layer of the cable core located outside the inner layer of the cable core; it is characterized in that the inner layer of the cable core is composed of a reinforcing member 9 located in the center, four inner layer coaxial electrical units distributed along the outer edge of the reinforcing member and located in the corresponding The filling rope 10 in the outer gap of the adjacent inner layer coaxial electric unit is formed, and each inner layer coaxial electric unit is composed of an inner conductor 4, an insulating layer 5 covering the inner conductor, and an outer conductor located outside the insulating layer 6. The insulating tape located outside t...
Embodiment 2
[0063] please see Figure 4 , and refer to Figure 1 to Figure 3 , the optical cable with the coaxial electric unit is basically the same as the embodiment 1, the difference is that the solid filling bar can be other multiple; it can also be one; it can also be like Figure 4 Also has a small solid filler strip to round out the outer layer of the cable core.
[0064] Figure 4 The medium and small solid filling strips are located next to the ground wire and in the middle of the two solid filling strips 2 .
[0065] In the present invention, the coaxial power line unit and the optical cable unit are organically twisted into a cable core, the cable core is covered with a metal shielding tape, and a layer of plastic sheath is extruded outside the tape; it is a 4G base station signal transmission system. The processing unit BBU (BasedBandUnit) is ideal for transmitting optical signals and providing power supply cables for the remote radio unit RRU (RemoteRadioUnit); it can also b...
