施工方法：FTTX工程中大规模使用皮线光缆，主要采用了两种接续方式：一种是以冷接子为主的光缆冷接技术（物理接续），一种是以熔接机为工具的热熔技术。
冷接技术：光纤冷接子是两根尾纤对接时使用的，它内部的主要部件就是一个精密的v型槽，在两根尾纤拨纤之后利用冷接子来实现两根尾纤的对接。操作起来更简单快速，比用熔接机熔接省时间。从表面上看，冷接操作简单快速，比熔接机热熔节省时间，但是的冷接技术还主要应用在光缆通信中断后应急应用。

冷接技术存在明显缺陷：
（1）冷接损耗大。由于采用物理接续，两根光纤*靠V型槽和匹配液来实现接续，这样的损耗明显要大于热熔连接点。在FTTX工程中，虽然对于线路的损耗要求没有干线要求严格，但是大损耗点就是潜在的故障点。
（2）使用寿命短，维护成本高。冷接技术中，匹配液的作用很重要。引用运营商客户统计的数据，进口的匹配液，一般的寿命会在3年左右，而国产的匹配液，寿命只有1.5~2年。这样，增加的维护的成本。而且一个冷接子的成本一般会在30到50元左右（可拆卸重复利用，但是拆卸后再用的精准度大大降低，所以冷接子标称是可重复，实际是在施工过程中都是只用一次的），实际使用维护成本高。

热熔技术热熔技术的优点：
（1）、熔接损耗小。两根光纤采用热熔技术，按照干线标准来进行的熔接，大大降低了熔接损耗。
（2）、使用寿命长，维护成本低。由于热熔标准按照干线施工进行要求，一般熔接点的寿命都会和普通光缆的寿命相差不多，不存在单个点的寿命问题。^[1] 
入户方式：
1 、用户室内布线：在FTTH工程中，用户室内布线是zui为复杂的环节，考虑的因素较多。既要保证线路安全，又要兼顾室内美观，同时还要施工便利，传统的单芯室内光缆已不能满足现阶段FTTH工程室内布线的要求。威普讯皮线光缆作为传统室内光缆的替代品，可以适应大多数室内布线条件，例如能以20mm的弯曲半径转弯，可以承担人踩在光缆上面的侧压力，及工程施工拖拽带来的拉力。同时，配合多种现场连接器，可以在zui短时间内实现现场成端、对接。所以，威普讯皮线光缆是FTTH室内布线的选择。

2、楼内垂直水平布线：与用户室内布线一样，威普讯皮线光缆也适合于楼内垂直水平布线。水平布线对光缆要求并不十分苛刻，但垂直布线必须要求光缆具备一定强度的抗拉性能。威普讯皮线光缆zui大可承受短期200牛顿、*100牛顿的拉力，因此可以保证在一定的高度范围内，皮线光缆垂直布线的施工安全和性能稳定。
3、自承式架空入户布线：自承式“8”字布线光缆由于具有金属吊线单元，所以抗拉性能更强，可承受50米的跨距。光缆在室外以架空方式敷设，入户前将金属吊线单元剪断，固定在固定器上，剩余光缆剥离金属吊线后采用皮线光缆引入室内。
4、 管道入户布线：由于管道映射光缆相比皮线光缆较硬，抗拉强度更高，同时光缆内含阻水材料，可减少户外雨水侵蚀，所以比较适合较长距离户外管道敷设。威普讯管道映射光缆采用全非金属结构，从而避免了引雷入室。光缆入户以后，剥离其外护层、阻水材料及加强件，直接用中间的皮线光缆进行室内布线，继承了皮线光缆室内布线的所有优势，同时减少了室外室内光缆接续的环节。

Large-scale construction methods: FTTX engineering use skin line cable, mainly adopts the two connection ways: a predominantly cold subgroups cable cold technology (physical connection), is a kind of a welding machine tool of the hot melt technology.
Cold cold technology: fiber subgroups is used when two tail fiber docking, it is a major part of the internal a precision of v groove, after two tail fiber dial fiber using cold subgroups to achieve docking two tail fiber.Operation more simply and quickly, than with welding machine welding save time.On the surface, cold joint operation simply and quickly, than hot melt welding machine saves time, but the cold technology is mainly used in optical fiber cable communication interrupt after emergency applications.
Cold technology has obvious flaw:
(1) cold after big loss.Due to adopting physical connection, two optical fibers compley accomplished by V groove and matching liquid succeeded, such loss is more than hot melt connection point.In FTTX engineering, while for line loss main requirements are not strict, but big loss is a potential point of failure.
(2) the short service life, high maintenance costs.The technology of cold shut, the role of matching liquid is very important.Operator customers of statistical data, the import of matching liquid, the life of the general will be in 3 years or so, and domestic matching liquid, only 1.5 ~ 2 years of life.In this way, increase the cost of maintenance.And the cost of a cold subgroups are generally in 30 to 50 yuan (removable reuse, but remove the reoccupy after precision greatly reduced, so the cold subgroups, nominal is repeatable, actual it is in the process of construction are used only once), the actual use of high maintenance costs.

Hot melt technology advantages:
(1), welding low loss.USES the hot melt technology, two optical fibers in accordance with the main standards for welding, greatly reduce the loss of the weld.
(2), long service life and low maintenance costs.Due to the hot melt standards carried out in accordance with the main construction requirements, the life of the general fuse contact will is similar to the life of the ordinary optical fiber phase, there is no single point of life.[1]
Enter a way:
1, user indoor wiring: in FTTH engineering, user indoor wiring is the most complicated part, considering many factors.Both to ensure the safety of the line, and to give attention to both indoor and beautiful, as well as the construction is convenient, the traditional single core indoor optical fiber cable can not meet the requirements of the present stage engineering FTTH indoor wiring.Wei's dispatch of skin line as a substitute for traditional indoor optical fiber cable, fiber optic cable can adapt to most indoor wiring conditions, such as the bending radius turn to 20 mm, can take one step on the cable above the lateral pressure, and drag the construction pulling force.At the same time, cooperate with multiple field connector, can in the shortest time for the connection of the scene into side,.So, wei's skin line cable is the best choice for FTTH indoor wiring.
2, the vertical level inside the building wiring: indoor wiring with users, wei's dispatch skin line cable also suitable for the vertical level inside the building wiring.Horizontal cabling for fiber optic cable is not very demanding, but vertical wiring must demand have a certain strength of the fiber optic cable tensile performance.Wei's dispatch of skin line cable can withstand short-term biggest 200 Newton, 100 Newton tension for a long time, so it can guarantee within the scope of a certain height, leather line of vertical cable wiring construction safety and stable performance.
3, messenger overhead door wiring: messenger "8" the word unit wiring cable suspension wire with metal, so the tensile performance is stronger, can withstand the span 50 meters.Cable laying in overhead way, outside door before the metal unit messenger wire cut, fixed on the special holder, remaining after cable stripping metal suspension wire with leather line cable into the interior.
4, pipeline household wiring: because the pipeline mapping fiber cable harder than leather line, higher tensile strength, fiber containing block water material at the same time, can reduce outdoor rain, so more suitable for long-distance outdoor pipe laying.Wei's ecommunications cable pipeline mapping using nonmetallic structure, so as to avoid the lead thunder home invasion.After the cable entry, spin off its outer covering, the water resistance materials and reinforcement, and directly in the middle of the leather line cable indoor wiring, inherited the leather line of all the advantages that the indoor wiring, fiber optic cable at the same time reduce the indoor outdoor optical link.
