Example Embodiment

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] like figure 1 As shown, a ribbon-shaped communication optical cable includes 4 optical fiber ribbon channels placed symmetrically in the center, and a soft steel wire reinforcement 1 is provided at the center of the 4 optical fiber ribbon channels and adjacent to each other. The outer side of the steel wire reinforcement is wrapped with a circle of water-blocking tape 6 , and the outside of the water-blocking tape 6 is covered with a layer of steel strip longitudinal cladding 7 , and the outside of the steel strip longitudinal cladding 7 is covered with a layer of polyethylene outer sheath 8 . By installing a soft steel wire reinforcement in the center of the 4 optical fiber ribbon channels and adjacent to each other, the flatness of the optical fiber ribbon can be excellently ensured, and it is suitable for installation in the same office building or in a relat...

Abstract

The invention provides a band-shape communication optical cable. The optical cable comprises 4 optical fiber band channels which are placed in a centrally symmetrical mode. Centers of the 4 optical fiber band channels and adjacent positions of each two channels are provided with soft steel wire reinforcement components respectively. A circle of waterproof wrapping tapes wraps outer sides of the optical fiber band channels and the soft steel wire reinforcement components. A steel-band longitudinal cladding layer sleeves an outer side of the waterproof wrapping tapes. A layer of polyethylene outer sheath sleeves an outer side of the steel-band longitudinal cladding layer. Through setting the soft steel wire reinforcement components at the centers of the 4 optical fiber band channels and the adjacent positions of each two channel respectively, flatness of optical fiber bands can be well guaranteed; in a same office building or areas which are close to each other, cables are not intersected, normal usage of the cables is not influenced and optical path transmission efficiency is increased; and simultaneously, through the multiple circles of the waterproof wrapping tapes, waterproof performance of optical cables is guaranteed.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a ribbon communication optical cable. Background technique [0002] Fiber optics are the next generation transmission medium and have some distinct advantages over copper media. Because the optical fiber does not radiate electronic signals to the outside world, the network using the optical fiber medium has greatly improved in terms of security, reliability and network performance. The bandwidth of optical fiber transmission greatly exceeds that of copper cables, and the maximum connection distance supported by optical fiber is more than two kilometers. It is an inevitable choice to build a large-scale network. With the continuous development of optical fiber networks, this requires optical cables with larger core count, small outer diameter, high density, and easy to connect quickly, so ribbon optical cables appear. The key technology of optical fiber ribbon is paralle...
