Description
Technical field
This utility model is related to MPO type optical cables, particularly wireless radio remote unit multicore MPO type optical cables.
Background technology
In base station signal transmission system, the cable between Base Band Unit to wireless radio remote unit is referred to as wirelessly penetrated
Frequency extension unit cable, the optical cable for wherein providing signal transmission for extension unit are referred to as optical cable for wireless radio remote unit.
Optical cable for wireless radio remote unit is mainly used in locally zooming out positioned at same website, length be usually 100m～
300m, when needing longer distance to zoom out, is preferably attached using outdoor optical cable, and two ends reconnect wireless radio remote unit and use
Optical cable.Be applied to extension unit optical cable must have the performance of the environment of resistance to indoor and outdoors, wider use temperature range, compared with
Good mechanical performance and environmental performance, fire resistance energy etc..
Utility model content
The purpose of this utility model is the shortcoming for overcoming prior art, there is provided a kind of high tensile performance, high intensity and
Pliability good wireless radio remote unit multicore MPO type optical cables.
The purpose of this utility model is achieved through the following technical solutions：Wireless radio remote unit multicore MPO type light
Cable, it include that oversheath, inner sheath, reinforcement A, reinforcement B and optical fiber, described oversheath are coated on the cylindrical of reinforcement A
On, described reinforcement A be coated on inner sheath cylindrical on, and be additionally provided with least one on reinforcement A and open hawser, described
In the cavity of inner sheath, described reinforcement B is filled in the cavity between optical fiber and inner sheath optical fiber.
Described reinforcement A and reinforcement B are aramid fiber reinforcement.
Described oversheath and inner sheath are halogen-free low-smoke flame retardant material and make.
Described hawser of opening is for one, and is distributed along optical fiber axial direction, and opens hawser and worked out by aramid fiber.
This utility model has advantages below：MPO types optical cable of the present utility model, is provided with dual layer reinforcement, and wherein
Hawser is provided with out in one reinforcement, the structural strength of optical cable is enhanced, by reinforcement and hawser is opened so that optical cable has
Superpower tensile resistance, so that optical cable is zoomed out apart from elongated, and whole optical cable is without metal, and pliability is good, be manufactured into
This is low, after burning, discharges without harmful gass, and environmental-protecting performance strengthens.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure, 1- oversheaths, 2- reinforcement A, 3- inner sheaths, 4- reinforcement B, hawser opened by 5- optical fiber, 6-.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described, protection domain of the present utility model be not limited to
Lower described：
As shown in figure 1, wireless radio remote unit multicore MPO type optical cables, it includes oversheath 1, inner sheath 3, strengthens
Part A2, reinforcement B4 and optical fiber 5, described oversheath 1 be coated on reinforcement A2 cylindrical on, described reinforcement A2 is coated on
Inner sheath 3 cylindrical on, and be additionally provided with least one on reinforcement A2 and open hawser 6, described optical fiber 5 is arranged on inner sheath 3
Cavity in, described reinforcement B4 is filled in the cavity between optical fiber 5 and inner sheath 3, by reinforcement A2, reinforcement
B4, improves the tensile resistance of optical cable so that the structural strength of optical cable strengthens.
In the present embodiment, described reinforcement A2 and reinforcement B4 are aramid fiber reinforcement, and aramid fiber reinforcement has good
Good flame retardant effect, its limited oxygen index (LOI) are therefore will not continue to burn when it leaves flame, improve light more than 28
The safety that cable is used, and the structural strength of aramid fiber reinforcement is higher, and therefore there is very strong tensile resistance, its intensity energy
3.6GPa is reached, extension modulus is 131GPa, it is 2.8% that rate is stretched out in fracture, so as to ensure that the tensile resistance of optical cable.
In the present embodiment, described oversheath 1 and inner sheath 3 are halogen-free low-smoke flame retardant material and make, so that
Optical cable will not send toxic smog in burning, so as to avoid impact of the optical cable burning to surrounding enviroment.
In the present embodiment, described hawser 6 of opening is one, and is axially distributed along optical fiber 5, and it is fine by aramid fiber to open hawser 6
Dimension is worked out, and opens the structural strength that hawser 6 further strengthens optical cable, improves the tensile strength of optical cable, so as to prolong
The service life of optical cable is grown.
