Abstract
The invention discloses a tight-buffered optical cable used for 3G network baseband remote technology, comprising a plurality of fibers; the outside surface of every fiber is provided with a tight layer; the periphery of a plurality of tight layers is covered with an aramid silk reinforced element; the aramid silk reinforced element is externally provided with an outer sheath; the optical cable is especially used for optical signal transmission from BBU/MU (main station baseband control unit) to RRU (remote radio unit). The optical cable replaces the a plurality of traditional feeder cables which are heavy and expensive, thereby simplifying construction and lowering cost.
Description
Technical field
The present invention relates to a kind of tight sleeve optic cable that is used for the 3G network baseband remote technology.
Background technology
In 3G network is built, power amplifier and low noise amplifier, radio-frequency (RF) transceiver even intermediate frequency unit need be zoomed out to the areal coverage away from the base station as remote end module, be called remote technology.Remote technology generally comprises that radio frequency zooms out, intermediate frequency zooms out, three kinds of baseband extensions etc., radio frequency zooms out the distance that zooms out that realizes with the intermediate frequency remote technology and is respectively about 100 meters and 300 meters, and baseband extension is a fiber optic stretch, and its transmission range can reach tens kilometers, can realize that long distance zooms out.The core of fiber optic stretch technology is that baseband portion of base station (BBU+MU equipment) and radio frequency part (RRU) are separated, and the two connects with optical cable.Radio frequency part can be placed on indoor, outdoor as remote end module, networking is very flexible.
In base station deployment, adopt the fiber optic stretch technology to bring huge benefit, mainly show the following aspects for mobile operator:
The first, reducing the construction costs.Employing optical fiber connects, and substitutes many traditional feeder lines, can reduce feeder loss, has reduced the power requirement of power amplifier, thereby has reduced the base station equipment cost.
The second, cut operating costs.By to the reasonable utilization of current BTS resource and the concentrated placement of base station baseband part, reduce the lease expenses of base station.
The 3rd, realize quick networking.Base band and radio frequency placed apart allows engineering construction have very strong dirigibility, accelerated the engineering construction progress, ensures that 3G network disposes fast.
The 4th, be convenient to network optimization adjustment.Remote and the quick deployment characteristics of optical fiber make the position adjustment of antenna no longer be subjected to the restriction of base station, can make up the standard cellular structure according to base station surrounding environment characteristics, have reduced the difficulty of the network optimization.
The 5th, rationally utilize optical network resource.Can rationally utilize existing optical network resource, newly-built fiber cable network also can be used for other miscellaneous service, as data access, video monitoring etc.
The 6th, solve indoor covering.Past generally with indoor covering separately consideration separately, can cover unified consideration with outdoor and indoor signal after the employing fiber optic stretch technology, effectively utilize Internet resources, has reduced cost, has improved network coverage quality.
Summary of the invention
The present invention seeks to: a kind of tight sleeve optic cable that is used for the 3G network baseband remote technology is provided, be specifically designed to BBU/MU (main website baseband control unit) to the optical signal transmission between the RRU (remote radio unit (RRU)), this optical cable has replaced traditional heaviness and many expensive feeder cables, simplify construction, reduce cost.
Technical scheme of the present invention is: a kind of tight sleeve optic cable that is used for the 3G network baseband remote technology, comprise some optical fiber, the outside surface of every optical fiber is provided with tight sleeve layer, and the periphery of several tight sleeve layers is coated with the aramid yarn reinforcing element, the oversheath of aramid yarn reinforcing element peripheral hardware.
The further technical scheme of the present invention is: a kind of tight sleeve optic cable that is used for the 3G network baseband remote technology, comprise some optical fiber, the outside surface of every optical fiber is provided with tight sleeve layer, and the periphery of several tight sleeve layers is coated with the aramid yarn reinforcing element, the oversheath of aramid yarn reinforcing element peripheral hardware; Described tight sleeve layer is the double-deck UV resin that is coated in the optical fiber outside surface; Described oversheath adopts polyurethane material.
Advantage of the present invention is:
1, cable configuration compactness, external diameter is little, and is in light weight, and bending radius is little, is convenient to construction.
2, be suitable for vertical run from the antenna of cat head or roof to machine room.
3, adopt the tight tube fiber structure, tight sleeve layer adopts double-deck UV resin-coating, makes optical fiber have better temperature, anti-bending and mechanical protection performance.
4, adopt the anti-element of opening of high strength aramid yarn, optical cable has good flexibility and favorable mechanical environmental performance.
5, cable jacket adopts polyurethane material, has excellent weatherability, ageing-resistant performance, wearing quality and fire resistance, both can use in outdoor rugged surroundings, also can be in indoor use.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described:
Fig. 1 is a structural representation of the present invention.
Wherein: 1 optical fiber; 2 tight sleeve pipes; 3 aramid yarn reinforcing elements; 4 oversheaths; 5 double-deck UV resins.

Zooming out optical cable among the present invention, is to be specifically designed to BBU/MU (main website baseband control unit) to the optical signal transmission between the RRU (remote radio unit (RRU)), and this optical cable has replaced traditional heaviness and many expensive feeder cables, simplifies construction, reduces cost.
Dragging optical cable is as the transmission medium of fiber optic stretch technology, and its environment for use is very complicated, therefore has following characteristics:
1, cable configuration compactness, external diameter is little, and is in light weight, and bending radius is little, constructability.
2, be suitable for vertical run from the antenna of cat head or roof to machine room.
3, adopt the tight tube fiber structure, tight sleeve layer adopts double-deck UV resin-coating, and optical fiber is had more Good temperature, anti-bending and mechanical protection performance.
4, adopt the anti-element of opening of high strength aramid yarn, optical cable has good flexibility and good machinery Environmental performance.
5, cable jacket adopts polyurethane material, has excellent weatherability, ageing-resistant performance, wear-resisting Property and fire resistance both can have been used in outdoor adverse circumstances, also can be in indoor use.
