Abstract
The utility model relates to an optical cable, in particular to a flame-retardant soft optical cable used for indoor communication, which comprises a cable core, a filling ointment layer and a tight sleeve pipe layer, wherein the filling ointment layer and the cable core are tightly fastened by the tight sleeve pipe layer, the tight sleeve pipe layer is a fluor resin sleeve pipe layer, and the outmost layer of the optical cable is a flame-retardant outer protective sleeve layer. The utility model has the advantages that the flame-retardant sleeve materials meet the requirement of the soft optical cable as the indoor product on the flame-retardant performance, the flame-retardant soft optical cable is light and soft, and is convenient for the installation and maintenance in a limited space, and the passive effect can be basically realized in a process from a local end to users.
Description
Technical field
The utility model relates to a kind of optical cable, particularly a kind of fire-retardant flexible optical cable that is used for indoor communications.
Background technology
Along with the development of information cause, in the environment of existing network communication, the transmission speed of file, the security of information are all had very high requirement, but ordinary optical cable can not satisfy these demands owing to its structural reason.Existing optical cable because of cost problem and technical maturity factor not necessarily fire-retardant, even certain anti-flammability is arranged, do not reach the requirement that low cigarette or Halogen do not injure personnel yet, cause optical cable security deficiency, and existing optical cable cable this as hard, unsuitable installation and maintenance.
Summary of the invention
The utility model is intended to overcome existing optical cable poor fire, and the not soft problem of cable itself provides a kind of fire-retardant flexible optical cable.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of fire-retardant flexible optical cable comprises cable core, factice for filling layer and tight casing layer, and factice for filling layer and cable core are fastening by tight casing layer, and it is characterized in that: described tight casing layer is the tight casing layer of fluororesin, and the optical cable outermost layer is fire-retardant external sheath layer.
Described fire-retardant external sheath layer is a low-smoke non-halogen flame-retardant PVC layer.
Between described fire-retardant external sheath layer and the tight casing layer is tension aramid fiber layer.
The utility model advantage:
1, flame-retardant sheath material has satisfied flexible optical cable as the requirement of indoor product to fire resistance.
2, its installation and maintenance light and handy, that softness is convenient to the finite space has changed the rigidity stiffener of ordinary optical cable, with the aramid yarn generation of softness.
3, from the local side to user, the centre can be accomplished passive basically; Broader bandwidth, long distance just in time meets the extensive operational mode of operator, and the agreement of supporting is more flexible; Transmission speed and security etc. are not problems.

1. cable cores, 2. factice for filling layers, 3. tight casing layer 4. fire-retardant external sheath layer 5. tension aramid fiber layer wherein
Embodiment
A kind of fire-retardant flexible optical cable, comprise cable core, factice for filling layer and tight casing layer, factice for filling layer and cable core are fastening by tight casing layer, tight casing layer is the tight casing layer of fluororesin, the optical cable outermost layer is fire-retardant external sheath layer, fire-retardant external sheath layer is a low-smoke non-halogen flame-retardant PVC layer, is tension aramid fiber layer between fire-retardant external sheath layer and the tight casing layer.
The utility model is for solving the fire-resistant safety problem of the optical cable of registering one's residence; adopt fire-retardant low smoke and zero halogen material to wrap up cable core as restrictive coating; in case under extreme case outer protective sleeve by roastingization of fire and flue gas to the injury of indoor occupant, both protected optical fiber, prevented that again personnel's is injured.
Common flexible optical cable is not necessarily fire-retardant because of cost problem and technical maturity factor, even certain anti-flammability is arranged, does not also reach low cigarette or Halogen and does not injure personnel.The utility model is with the improvement that other flexible optical cable product is compared, and has adopted the restrictive coating of low smoke and zero halogen and compatible better perfluoroethylene third rare resin with optical fiber to make tight casing layer.
