施工方法：FTTX工程中大規(guī)模使用皮線光纜，主要采用了兩種接續(xù)方式：一種是以冷接子為主的光纜冷接技術(shù)（物理接續(xù)），一種是以熔接機(jī)為工具的熱熔技術(shù)。
冷接技術(shù)：光纖冷接子是兩根尾纖對(duì)接時(shí)使用的，它內(nèi)部的主要部件就是一個(gè)精密的v型槽，在兩根尾纖撥纖之后利用冷接子來實(shí)現(xiàn)兩根尾纖的對(duì)接。操作起來更簡(jiǎn)單快速，比用熔接機(jī)熔接省時(shí)間。從表面上看，冷接操作簡(jiǎn)單快速，比熔接機(jī)熱熔節(jié)省時(shí)間，但是的冷接技術(shù)還主要應(yīng)用在光纜通信中斷后應(yīng)急應(yīng)用。

冷接技術(shù)存在明顯缺陷：
（1）冷接損耗大。由于采用物理接續(xù)，兩根光纖*靠V型槽和匹配液來實(shí)現(xiàn)接續(xù)，這樣的損耗明顯要大于熱熔連接點(diǎn)。在FTTX工程中，雖然對(duì)于線路的損耗要求沒有干線要求嚴(yán)格，但是大損耗點(diǎn)就是潛在的故障點(diǎn)。
（2）使用壽命短，維護(hù)成本高。冷接技術(shù)中，匹配液的作用很重要。引用運(yùn)營(yíng)商客戶統(tǒng)計(jì)的數(shù)據(jù)，進(jìn)口的匹配液，一般的壽命會(huì)在3年左右，而國(guó)產(chǎn)的匹配液，壽命只有1.5~2年。這樣，增加的維護(hù)的成本。而且一個(gè)冷接子的成本一般會(huì)在30到50元左右（可拆卸重復(fù)利用，但是拆卸后再用的精準(zhǔn)度大大降低，所以冷接子標(biāo)稱是可重復(fù)，實(shí)際是在施工過程中都是只用一次的），實(shí)際使用維護(hù)成本高。

熱熔技術(shù)熱熔技術(shù)的優(yōu)點(diǎn)：
（1）、熔接損耗小。兩根光纖采用熱熔技術(shù)，按照干線標(biāo)準(zhǔn)來進(jìn)行的熔接，大大降低了熔接損耗。
（2）、使用壽命長(zhǎng)，維護(hù)成本低。由于熱熔標(biāo)準(zhǔn)按照干線施工進(jìn)行要求，一般熔接點(diǎn)的壽命都會(huì)和普通光纜的壽命相差不多，不存在單個(gè)點(diǎn)的壽命問題。^[1] 
入戶方式：
1 、用戶室內(nèi)布線：在FTTH工程中，用戶室內(nèi)布線是zui為復(fù)雜的環(huán)節(jié)，考慮的因素較多。既要保證線路安全，又要兼顧室內(nèi)美觀，同時(shí)還要施工便利，傳統(tǒng)的單芯室內(nèi)光纜已不能滿足現(xiàn)階段FTTH工程室內(nèi)布線的要求。威普訊皮線光纜作為傳統(tǒng)室內(nèi)光纜的替代品，可以適應(yīng)大多數(shù)室內(nèi)布線條件，例如能以20mm的彎曲半徑轉(zhuǎn)彎，可以承擔(dān)人踩在光纜上面的側(cè)壓力，及工程施工拖拽帶來的拉力。同時(shí)，配合多種現(xiàn)場(chǎng)連接器，可以在zui短時(shí)間內(nèi)實(shí)現(xiàn)現(xiàn)場(chǎng)成端、對(duì)接。所以，威普訊皮線光纜是FTTH室內(nèi)布線的選擇。

2、樓內(nèi)垂直水平布線：與用戶室內(nèi)布線一樣，威普訊皮線光纜也適合于樓內(nèi)垂直水平布線。水平布線對(duì)光纜要求并不十分苛刻，但垂直布線必須要求光纜具備一定強(qiáng)度的抗拉性能。威普訊皮線光纜zui大可承受短期200牛頓、*100牛頓的拉力，因此可以保證在一定的高度范圍內(nèi)，皮線光纜垂直布線的施工安全和性能穩(wěn)定。
3、自承式架空入戶布線：自承式“8"字布線光纜由于具有金屬吊線單元，所以抗拉性能更強(qiáng)，可承受50米的跨距。光纜在室外以架空方式敷設(shè)，入戶前將金屬吊線單元剪斷，固定在固定器上，剩余光纜剝離金屬吊線后采用皮線光纜引入室內(nèi)。
4、 管道入戶布線：由于管道映射光纜相比皮線光纜較硬，抗拉強(qiáng)度更高，同時(shí)光纜內(nèi)含阻水材料，可減少戶外雨水侵蝕，所以比較適合較長(zhǎng)距離戶外管道敷設(shè)。威普訊管道映射光纜采用全非金屬結(jié)構(gòu)，從而避免了引雷入室。光纜入戶以后，剝離其外護(hù)層、阻水材料及加強(qiáng)件，直接用中間的皮線光纜進(jìn)行室內(nèi)布線，繼承了皮線光纜室內(nèi)布線的所有優(yōu)勢(shì)，同時(shí)減少了室外室內(nèi)光纜接續(xù)的環(huán)節(jié)。

3. The sheath color comply with YD/T1258.5-2005, other color can also be a user requirements;
4. The sheath material also can be other materials required by the user;
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.
