Abstract
The utility model discloses an indoor single-fiber optical cable, which comprises an optical fiber, a tubular tight sleeving layer, wherein the tight sleeving layer is coated outside the optical layer; a reinforced element is coated outside the tight sleeving layer and made of aramid fibers; a protective sleeve layer is arranged outside the reinforced element and made of PVC (polyvinyl chloride) or LSZH (low smoke zero halogen) materials; and the outer diameter of the tight sleeved optical fiber is 900um or 600um. The indoor single-fiber optical cable is simple in structure, small in outer diameter, light in weight, easy in stripping, slow in attenuation, high in flexibility, low in laying cost, excellent in tensile performance, resistant to corrosion, water and ultraviolet rays, excellent in anti-combustion and environment-friendly performances, free of electromagnetic interference and long in service life.
Description
Technical field:
The utility model relates to the inside cable field, relates in particular to the indoor flexible optical cable of a kind of single core.
Background technology:
Optical cable is the main delivery means of the various Information Networks of current information society.Optical cable (optical fiber cable) mainly is by light transmitting fiber (thin glass fiber as hair) and plastic protective sleeve pipe and plastic peel formation, does not have metals such as gold, silver, copper aluminium in the optical cable, does not generally have recovery value.Optical cable is that the optical fiber of some is formed the cable heart according to certain way, is surrounded by sheath outward, and the also coating outer jacket that has is in order to realize a kind of communication line of optical signal transmission.
Tight tube fiber (being enclosed with the optical fiber of tight sleeve layer) is a base components of making various flexible optical cables, also is used for the connecting line of the active and passive device of laser instrument tail optical fiber and all kinds of light.
The utility model content:
The purpose of this utility model provides the indoor flexible optical cable of a kind of single core, is applicable to wire jumper or tail optical fiber that optical fiber flexibly connects, indoor vertical shaft level and the wiring of forced draft level, and instrument, communication facilities are interconnected.
Technical scheme of the present utility model is as follows:
The indoor flexible optical cable of a kind of single core comprises optical fiber, tight sleeve layer, and it is characterized in that: described outer fiber is enclosed with tight sleeve layer, and tight sleeve layer is a tubular, and the described tight sleeve layer outside is enclosed with reinforcing element, and the described reinforcing element outside is provided with restrictive coating.
The indoor flexible optical cable of described single core is characterized in that: described reinforcing element is an aramid fiber, and described jacket material adopts PVC or LSZH low smoke and zero halogen material.
The indoor flexible optical cable of described single core is characterized in that: the external diameter of described tight tube fiber is 900um or 600um.
Compare with traditional indoor flexible optical cable of single core, have following excellent part:
1. adopt the tight tube fiber external diameter little, in light weight, easily peel off, decay low, have high flexibility;
2. can directly connect between the tight tube fiber optical cable, need not crossover sub box and tail optical fiber, need not to clean waterproofing unction, thereby laid down cost be low;
3. adopt the aramid fiber reinforcing element, make optical cable have excellent tensile property;
4. the restrictive coating material adopts PVC or LSZH low smoke and zero halogen material, not only corrosion-resistant, waterproof, antiultraviolet, and also fire resistance, environmental-protecting performance are superior;
5. full dielectric structure is not subjected to electromagnetic interference (EMI);
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The indoor flexible optical cable of a kind of single core, comprise optical fiber 1, tight sleeve layer 2, optical fiber 1 outside is enclosed with tight sleeve layer, tight sleeve layer 2 is a tubular, tight sleeve layer 2 outsides are enclosed with reinforcing element 3, and reinforcing element 3 outsides are provided with restrictive coating 4, and reinforcing element 3 is an aramid fiber, restrictive coating 4 materials adopt PVC or LSZH low smoke and zero halogen material, and the external diameter of tight tube fiber is 900um or 600um.
