Problems solved by technology
[0006] The cable cores of the existing road surface micro-groove optical cables are generally 4-12 cores, and the information transmission capacity is small. With the continuous increase of data transmission volume, the line signal is often unstable, which increases the frequency and maintenance of road surface micro-groove optical cables. cost
In addition, in areas where there are many termites and rats, the original optical cable cannot be used stably for a long time

Embodiment Construction
[0020] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.
[0021] ginseng figure 1 as shown, figure 1 A schematic cross-sectional view of a pavement microgroove optical cable according to the present invention is shown.
[0022] In this embodiment, a pavement micro-groove optical cable comprises: a sheath 6, two loose tubes 3 are arranged straight and parallel in the sheath 6; an optical fiber 1 is arranged in the loose tube 3, and the optical fiber 1 is formed by water blocking The filament 2 (filler) is fixed in the loose tube 3; a soft buffer body 5 and a water-blocking aramid rod 4 are arranged between the loose tube 3 and the sheath 6 (5, 4 are reinforcing members).
[0023] In the present invention, two loose tubes 3 are arranged in the optical cable of the same size at the same time, which doubles the density of the optical fiber, improves the information transmis...

The invention belongs to the technical field of optical cables and in particular relates to a pavement microgroove optical cable. The pavement microgroove optical cable comprises a sheath, wherein two loose casings are arranged in the sheath straightly in parallel; optical fibers are arranged in the loose casings and fixed in the loose casings through fillers; a reinforcing member is arranged between the sheath loose casings and the sheath. According to the pavement microgroove optical cable, the double casings are arranged in same-sized optical cables, so that density of the optical fibers is doubled, thus improving information transmission capacity and saving the maintenance cost.
Description
technical field [0001] The invention belongs to the technical field of optical cables, in particular to a micro-groove optical cable on road surfaces. Background technique [0002] In the initial stage of the construction of communication lines for operators, due to the single business and limited construction funds, only the construction needs of base station transmission optical cables were considered during pipeline construction. At present, with the continuous increase of business volume and the continuous improvement of service requirements, the distance between base stations has been reduced from several kilometers to hundreds of meters, making more and more optical cables connecting base stations, which in turn requires more pipeline resources to support the transmission network building. [0003] In recent years, the demand for data services from the government and enterprises has grown rapidly, and data services have become the focus of competition among operators....
