室内双芯（2芯）皮线光缆（共为通信制造）

 室内双芯（2芯）皮线光缆是一种新型的入户光缆全名是2芯蝶形引入光缆，俗称皮线光缆，因为体积小重量轻，适用于光缆入户的情况，布线时可以根据现场的距离进行裁减，大大提供了工程施工效率。

接入网用2芯蝶形引入光缆（俗称皮线光缆）分为两大系列：
1、非自承式2芯蝶形引入光缆：适用于室内的布线使用（1、2芯）。
2、自承式2芯蝶形引入光缆：适用于室外架空引入使用（1、2芯）

产品特性：通过在弹性方面的特殊设计，保证安装过程中光纤不易折断。在将光缆弯曲的时候，只需要在弯曲的位置将光缆放开，光缆就会自动回到原来的位置，不会导致变形或是在光缆护套上留下任何印记。无论是从哪个方向弯曲，光缆都很柔韧，使光纤可以很小的弯曲半径进行安装或缠绕。踏压,挤压,弯曲，打结不会影响光缆的传输损耗。光滑的光缆护套，耐磨耐用。该皮线光缆具有：外径小、重量轻、成本低、易敷设，施工快，且易于用手剥离出光纤，光缆柔软性能和弯曲性能好，可以像普通电话线一样柔软的使用，甚至在光缆折叠和打结受力以后光纤芯都不会折断，特别适合在建筑物内的小角度的铺设安装的特点。该皮线光缆主要用途有：光纤入户（FTTH）工程中，作为末端入户光缆使用。

适用场合：
1、建筑智能化系统工程中，建筑物内各种需要光缆传输的连接。
2、建筑物内的各种光通信网络的光缆连接。
3、火灾自动报警及消防联动系统的光缆连接。
4、建筑物内、大型公众场所、停车场、居住小区、公园等，需要建设安防监控系统的光缆连接。
5、弱电系统集成等光缆连接。
6、大型公众场合（如公园、音乐厅）的分散音响系统的光缆连接。
7、其他接入网领域需要使用引入光缆的场合。

Leather leather line 1 core cable (single core wire cable) is a new type of household fiber optical cable, introduced full name is a butterfly, commonly known as 1 core covered wire cable (single core skin line cable), because of small size light weight, suitable for the situation of the cable entry, wiring can be cut according to the distance, provides the construction efficiency greatly.
Butterfly is introduced into access network with a core cable (commonly known as 1 core skin line cable skin line, single core cable) is divided into two series:
1, 1 core butterfly is introduced into the messenger cable: suitable for indoor wiring used (1, 2, 4).
2, 1 core butterfly into messenger cable: suitable for outdoor use overhead introduced (1, 2, 4)
Product features: the special design in terms of elasticity, ensure the installation process of optical fiber is not easy to break.At the time of the bending of the cable, you just need to let go of the cable in bending position, the cable will automatically return to its original position, will not lead to deformation or leave any marks on the cable sheath.From which direction to bend, fiber optic cable are very flexible, making optical fiber can be installed or winding small bending radius.Pressure, extrusion, bending, knot will not affect the optical cable transmission loss.Smooth cable sheath, wear-resisting durable.The skin line 1 core cable (single core skin line cable) have: small diameter, light weight, low cost, easy installation, construction fast, ａnd easy to hand out optical fiber, optical fiber cable soft performance ａnd bending performance is good, can use soft like regular telephone line, even in the cable force after folding ａnd knot optical fiber core is not broken, especially suitable for the building of small Angle of the characteristics of the installation.The skin line 1 core cable main purposes are: optical fiber door (FTTH) projects, as a door at the end of the cable to use.
Applicable occasions:
1, building intelligent systems engineering, building various need of cable transmission connection.
2, building of all kinds of optical communication network cable connections.
3, automatic fire alarm ａnd fire linkage system of fiber optic cable connection.
4, buildings ａnd large public places, car parks, residential area, park, etc., need to build security monitoring system of cable connection.
5, fiber optic cable connection of weak current system integration.
(such as 6, large public park, hall) scattered sound system of fiber optic cable connection.
7, other areas need to use the introduction of optical cable access network.
Technical parameters:
According to different applications, the skin line 1 core fiber can be divided into messenger of the structure of steel reinforced fiber ａnd 1 without steel reinforced core wire cable.
