Description

Technical Field

[0001] The invention belongs to the field of optical cables, and in particular relates to an optical fiber ribbon cable with a regular polygonal cross section. Background Art

[0002] With the rapid development of communications technology, the use of high-core-count optical cables is increasing. Fiber optic ribbon cables, with their higher core density, are particularly favored by operators. However, with increasing competition and the need for lower costs, users are increasingly demanding higher core density, lower-cost fiber optic ribbon cables. This has led to ongoing research within the industry. The following are the results of the closest prior art searches conducted by the applicant throughout the entire R&D process, including before, during, and after R&D.

[0003] CN218037476U discloses a communication optical cable for a power dispatching network, comprising a communication unit comprising a protective member and a protective cover, wherein the outer edge of the protective member has a regular hexagonal cross-section, and the outer edge of the protective cover has a circular cross-section. The protective member is characterized in that it comprises six interlocking components, each of which comprises an outer wall, a first inclined wall, a second inclined wall, a third inclined wall, a fourth inclined wall, six first communication components, and six second communication components, with the first and second communication components all located within the protective member. The space utilization efficiency of the cable needs to be further improved, and the cable is not suitable for different optical fiber ribbons, such as the coexistence of rectangular optical fiber ribbons and parallelogram optical fiber ribbons, as the coexistence of these ribbons results in low space utilization.

[0004] CN113341520A discloses a central bundle tube type large core count ribbon optical cable, comprising an outer sheath and a cable core, characterized in that the cable core is formed by stacking optical fiber ribbons up and down, and the cross section of the stacked cable core is cross-shaped, wherein the middle layer of the cable core is stacked with 24 optical fiber ribbons to form a cross horizontally, and the upper and lower layers of the cable core are stacked with 12 optical fiber ribbons to form a cross vertically, the cable core is coated with a flexible film tight jacket layer, a water-blocking layer is arranged outside the flexible film tight jacket layer, and a circular cross-section outer sheath is coated outside the water-blocking layer, and the triangular space is not utilized.

[0005] CN111517637A discloses a rare earth-doped multi-core optical fiber, an optical fiber preform, and a preparation method and application thereof, belonging to the fields of optics and laser optoelectronics. The relative refractive index difference Δ1 of the central core of the optical fiber is between 0.12% and 0.17%, and the diameter D1 is between 10 and 20 μm. The relative refractive index difference Δ2 of the remaining cores surrounding the central core is between 0.07% and 0.12%, and the diameter D2 is between 12 and 25 μm. The core spacing L of each core is the same, and its size L is 16 to 30 μm. The inner cladding of the optical fiber is a regular octagon with an edge-to-edge spacing of 250 to 400 μm. The inner coating of the optical fiber is a low-refractive-index polymer with a relative refractive-index difference Δ3 of -5%. The outer coating of the optical fiber is a high-refractive-index coating with a relative refractive-index difference Δ4 of 3.5%. There is no technical inspiration for how to rationally utilize space to increase the core density of the optical fiber ribbon.

[0006] CN211265093U discloses a high-core-density optoelectronic composite cable comprising two identical composites and an outer sheath that integrally encases the composites. The composites are characterized by being composed of an integrated power transmission unit and a light transmission unit. The power transmission unit is semi-cylindrical in shape and comprises an insulating layer and a conductor with a semicircular or arcuate cross-section. The light transmission unit comprises a protective tube with a parallelogram cross-section and multiple optical fiber ribbons located within the internal cavity of the protective tube, each optical fiber ribbon containing multiple optical waveguides. The left side of the light transmission unit above the planar portion of the power transmission unit of one composite is affixed to the left side of the light transmission unit above the planar portion of the power transmission unit of the other composite. The parallelogram-shaped optical fiber ribbon is only suitable for a single parallelogram-shaped sheath, so technical personnel in the field are unaware of how to achieve expansion with a larger number of cores.
