Abstract
The utility model discloses an optical cable is connected to house lead in, include: the glass optic fibre, the cladding that are located the center are in outside covering, the cladding of glass optic fibre is in outside soft inoxidizing coating and the cladding of covering is in the outside hard inoxidizing coating of soft protective layer, the outside of hard inoxidizing coating has the freeze proof filling layer of heat preservation, it has outer rubber sheath layer to keep warm the outside of freeze proof filling layer, outer rubber sheath in situ portion has arranged many tensile lines along its circumferencial direction, central nylon wire and the many piece small -ga(u)ge wires of cladding in central nylon wire outside are drawn together to the tensile solenoid. In this way, the utility model has the advantages of simple and reasonable structure, have heat preservation frost resistance, be fit for using at cold rural areas.
Description
Technical field
The utility model relates to optical cable technology field, particularly relates to a kind of house lead in and connects optical cable.
Background technology
Fiber optic network communication enters daily life, has the advantage that transfer rate is fast, eliminates old cable transmission gradually.Buildings in city is all just arranged optical cable in unit, room in building course, and people only need simply to open application after moving in, and just can use optical fiber communication.
At present, Fiber-optic Communication Projects has also started to spread to vast rural area, rural area is all the family little Yuan of house not sharing an entrance with others, draw optical fiber to need to connect house lead in optical fiber from the optical fiber stake in roadside, then house lead in optical fiber is moved to inside family, existing this house lead in optical fiber, anti-freezing property is not good, optical fiber easily becomes fragile at low temperatures, thus easily occurs phenomenon of rupture, and existing this house lead in optical fiber is not suitable for using in cold rural area.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of house lead in and connects optical cable, simple and reasonable, has insulation anti-freezing property, is adapted at cold rural area and uses.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of house lead in connect optical cable, comprising: be positioned at the glass optical fiber at center, be coated on the covering of described glass optical fiber outside, be coated on the soft protective layer of described covering outside and be coated on the hard protection layer of described soft protective layer outside;
The outside of described hard protection layer has the freeze proof packed layer of insulation, the outside of the freeze proof packed layer of described insulation has external rubber sleeve layer, there are many tensile cord described external rubber sleeve layer inside along its circumferential directions, and described tensile cord comprises center nylon wire and is coated on many finer wires of nylon wire outside, center.
In the utility model preferred embodiment, the thickness of described covering is 15 ~ 18 μm.
In the utility model preferred embodiment, the thickness of described soft protective layer is 15 ~ 20 μm.
In the utility model preferred embodiment, the thickness of described hard protection layer is 20 ~ 23 μm.
