Abstract
The utility model discloses a double-core oblate indoor optical cable which comprises two optical fibers and tight sleeving layers. One tight sleeving layer, a strengthening component and an inner sheath layer are enwrapped on the outer side of each optical fiber in sequence; a hanging belt is arranged between the inner sheath layers; an outer sheath layer is enwrapped on the outer sides of the inner sheath layers; the two optical fibers are arranged in parallel; the section of the optical cable is oblate; the strengthening component is made of aramid fibers; the inner sheath layers and the outer sheath layer are made of PVC (Poly Vinyl Chloride) or LSZH (Low Smoke Zero Halogen) low-smoke zero halogen materials; and the external diameter of each tight sleeving optical fiber is 900 mum or 600 mum. The oblate double-core indoor optical cable has the advantages of simple structure, small diameter, light weight, low attenuation and is easy to strip. The oblate double-core indoor optical cable not only has high flexibility, low laying cost, excellent tensile property, corrosion resistance, water tightness and ultraviolet ray resistance, but also has excellent flame retardant property and environment protection performance, adopts an all-medium structure, is not disturbed by electromagnetic interference and has long service life.
Description
Technical field:
The utility model relates to the inside cable field, relates in particular to a kind of twin-core flat inside cable.
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 a kind of twin-core flat inside cable, 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:
A kind of twin-core flat inside cable, comprise two optical fiber, tight sleeve layer, it is characterized in that: described every outer fiber is enclosed with tight sleeve layer, reinforcing element, inner restrictive coating successively, is provided with suspender belt between the described inner restrictive coating, and the described inner restrictive coating outside is enclosed with external sheath layer.
Described twin-core flat inside cable is characterized in that: described two optical fiber are arranged in parallel, and the optical cable cross section is oblate.
Described twin-core flat inside cable is characterized in that: described reinforcing element is an aramid fiber, and described inner restrictive coating, external sheath layer material adopt PVC or LSZH low smoke and zero halogen material.
Described twin-core flat inside cable is characterized in that: described tight tube fiber external diameter, promptly the external diameter of tight sleeve layer is 900um or 600um.
Compare with traditional twin-core flat inside cable, 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. inside and outside 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);
6. the flat structure makes the optical fiber arrangements compactness.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
A kind of twin-core flat inside cable, comprise two optical fiber 1, tight sleeve layer 2, every optical fiber 1 outside is enclosed with tight sleeve layer 2, reinforcing element 3, inner restrictive coating 4 successively, be provided with suspender belt 5 between the inner restrictive coating 4, inner restrictive coating 4 outsides are enclosed with 6, two optical fiber 1 of external sheath layer and are arranged in parallel, the optical cable cross section is oblate, reinforcing element 3 is an aramid fiber, and inner restrictive coating 4, external sheath layer 6 materials adopt PVC or LSZH low smoke and zero halogen material, and the external diameter of tight tube fiber external diameter is 900um or 600um.
