Description

Technical Field

[0001] This utility model relates to the field of optical fiber cable and wire and cable technology, and in particular to a compact optoelectronic composite cable. Background Technology

[0002] With the increasing prevalence of 5G networks, existing 100Mbps Ethernet cables are no longer sufficient to meet the demand for higher speeds. Due to the limited penetration of 5G signals, it's typically necessary to install gigabit Ethernet cables in each room or directly connect fiber optic cables to indoor fiber optic signal receivers. Since existing Ethernet cables lack their own power supply, the power supply for the fiber optic signal receivers must be externally connected to other sockets, which is inconvenient, unsightly, and negatively impacts the user experience. Furthermore, to meet future communication expansion needs, the system should be designed to allow for the addition of fiber optic cables as needed.

[0003] To address the aforementioned technical shortcomings, developing a compact optical-electric composite cable that can meet future communication expansion needs and completely replace the existing 100Mbps network cable has become a technical problem that needs to be solved in the industry. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a compact optical-electric composite cable.

[0005] The compact optical-electric composite cable provided by this utility model adopts the following technical solution:

[0006] A compact optoelectronic composite cable includes an optical unit, an insulated core, an air-blown microtube, a tear cord, and an outer sheath. The insulated core is formed by covering an insulating layer around a conductor. The optical unit is formed by wrapping aramid fibers around an outer bundle of optical fibers, with an extruded sheath covering the outer side of the aramid fibers. The optical unit, the air-blown microtube, and the insulated core are twisted together to form a cable core. The cable core is covered with an outer sheath, and a tear cord is provided near the inner side of the outer sheath.

[0007] Preferably, the number of optical units is 1, the optical unit contains 1 optical fiber, and the number of insulated wire cores is 2.

[0008] Preferably, the sheath material of the optical unit is polyvinyl chloride or polyethylene.

[0009] Preferably, the air-blowing microtube is made of polyethylene or polybutylene terephthalate.

[0010] Preferably, the aramid wound in the optical unit is an aramid fiber material with a tensile strength of not less than 2000 MPa.

[0011] Preferably, the outer sheath is made of low-smoke, halogen-free, flame-retardant polyolefin material with an oxygen index of not less than 32%.

[0012] In summary, this utility model has at least one of the following beneficial technical effects:

[0013] 1. By combining optical units and insulated wire cores, a small-diameter optical-electric composite cable is formed, which can directly replace Category 5 network cable. The optical fiber and power line can be directly connected to the place where the equipment needs to be installed without additional wiring, ensuring the power supply and optical fiber access of the equipment.

[0014] 2. For future capacity expansion needs, the required optical fiber can be blown into the air-blowing microtube without replacing the optical cable, which is convenient and quick;

[0015] 3. A tear rope has been added to facilitate quick cable opening during construction operations. Attached Figure Description
