Fiber to the Home (FTTH) is becoming increasingly more common as b和width usage is exploding. This tremendous growth is driven in part by the rapid increase in Internet-connected devices 和 the use of data-heavy applications such as video on dem和. 服务提供商正在努力满足这一需求 更大的带宽 通过扩大部署 光纤电缆 到房子里，再到家里.
Service providers building these fiber networks all face a common challenge: the expense of the last mile in the optical network. 这对服务提供商来说至关重要, utilities 和 municipalities to have an optimized set of deployment options that help to reduce both capital 和 operational expenses.
The solutions presented in this article meet these challenges with several fiber deployment options from the drop point to 和 into the home.
OFS 以前的解决方案 for the Home can help residents take advantage of the Internet of Things (IoT), 它开始重新定义我们的工作和生活方式. 这些解决方案注重简单性, 成本效益和安装速度, 伴随安装前后的客户体验, time to revenue generation 和 reliable subscriber connections that help to improve profitability for the service provider.

PRE-TERMINATED vs. FIELD-TERMINATED滴
Pre-terminated 下降的解决方案 are increasingly used to install fiber to homes to save time 和 money in higher labor cost regions. Pre-terminated 下降的解决方案 consist of drop cables that are terminated 和 tested in the factory, 并可方便地插接到现场的落点终端和家用终端. Pre-terminated solutions offer lower costs 和 faster deployment 和 require less installation skill.
对于低劳动力成本市场，现场终止解决方案可能是首选. Field terminated solutions use drop cables which are terminated using fusion splicing or mechanical connectors in the field during installation. 它们提供了更简单的库存管理, 更低的材料成本和更容易的闲置管理, 但需要更长的时间来安装，并且需要更高技能的劳动力, 还有昂贵的现场终端工具和拼接机, 与预先终止的溶液相比.
第三种方法, 电缆一端预端接, 另一端电场终止, can solve the slack issue 和 allow an easy plug-in to the drop terminal 和 field termination at the home.
OFS offers all three of these drop solution options to fit the unique needs of each service provider. OFS预端接解决方案包括 EZ- Bend®电缆 这可以解决管理懈怠的挑战. EZ-Bend光纤电缆能够将松弛物绑成一个非常紧凑的束.
Providers typically use a combination of aerial 和 underground solutions to connect the last mile in a network to individual homes. A variety of factors including climate 和 existing infrastructure can influence solution selection.

将光纤连接到家中
OFS offers a complete portfolio of aerial 和 underground solutions including terminals, integrated splitters 和 drop cables to connect to the demarcation point of individual homes. From that location, a number of solutions can be leveraged to take optical fiber into the home.
空中部署 通常成本较低，并且首选在靠近家庭的地方安装电线杆. 在这个场景中, SlimBox®跌落终端安装在一根杆子上, 有或没有分离器, 然后通过电缆连接到多达16个家庭. Below grade drop deployment is preferred if there is an existing duct placed from the terminal location to the home, 或者当地法规要求使用低于等级的电缆.
首先，安装人员将馈线或配电电缆插入端子. The installer then extracts the number of fibers required 和 fusion splices them to a pre-terminated splitter or drop fiber. Aerial or underground drop cables are then deployed from the terminal to individual residences.
In the case of aerial cables, a drop cable is placed between the pole 和 a point near a home’s roof. The cable can be connected to a demarcation box 和 installed into the home through the attic or onto the side of the house at a demarcation box near the ground. 以避免不美观的架空电缆, 空中终端可以连接到地下电缆上. 空中部署, OFS offers the one to 24-fiber Mini LT Flat Drop Cable 和 the single-fiber Mini TB Flat Drop cable which contains 3 mm cordage that can be routed directly to an Optical Network Terminal (ONT).

地下电缆选择 包括单纤维EZ-Bend®3.0 mm和4.8mm加固电缆和ez弯曲可调电缆. The toneable cables enable easy above ground locating of buried cables to help avoid cable cuts when other underground systems are installed. 这些电缆是从架空终端沿电线杆向下安装到地面的, 然后将其掩埋，以尽量减少对景观的破坏, 或者拉进现有的管道. 然后将电缆连接到安装在房屋一侧的分界盒中, 最好是在靠近ONT的地方.
EZ-Bend电缆是首选的，因为它们的2.5 mm bend radius allows the cables to be coiled, bent 和 tied without creating signal degradation. These cables can also be buried or stapled/clipped 和 bent around the outer perimeter walls of a home to reach an entry point closer to the preferred ONT location.
新建房屋 为建筑公司和服务供应商提供了双赢的局面. 具有“内置”光纤连接的能力, 新房从一开始就是面向未来的, 房地产价值增加, 和 new home owners can become immediate subscribers without the expense of additional installation time. .
Subscribers can be connected faster using preterminated cables installed to 和 into homes during construction. OFS提供EZ-Bend 3.0 mm和4.8 mm cables that can be installed independently or in ducts using typical home wiring techniques, 例如用订书机或拉链捆扎电缆, 到稍后将放置ONT的位置或媒体面板. The home owner can later perform a “self install” by receiving an ONT from the service provider, 只需将EZ-Bend电缆组件和电源适配器插入ONT即可. OFS also provides a SlimBox Wall Plate that discretely blends into a home’s décor 和 facilitates ONT connections in the same way as a power outlet.
成屋 会对网络安装人员构成挑战吗, 考虑到各种各样可能的建筑结构. 除了, home designs 和 construction materials can vary greatly from country to country 和 even within countries. OFS解决方案 are purposefully designed 和 optimized to suit a variety of homes globally 和 offer maximum flexibility to on-site installers.
取决于目标市场, 供应商可以为天线选择终端和铺设电缆, 地下或混合解决方案. The solutions described are the most popular options 和 feature a variety of products as building block components. This modular product design approach allows service providers to also create custom solutions to meet the specific needs of their target markets.
