Hunan Jiahome Technology Co., Ltd Will Show You How to Choose A FTTH Outdoor Drop Cable ?

Fiber to the Home (FTTH) has revolutionized the telecommunications industry, providing high-speed internet and seamless connectivity for homes and businesses. One critical component of any FTTH installation is the outdoor drop cable, responsible for delivering fiber optic signals from the distribution point to the end-users’ premises. Selecting the appropriate outdoor drop cable is vital to ensure efficient and reliable data transmission. In this comprehensive guide, we will explore the key factors to consider when choosing an FTTH outdoor drop cable.

1.Fiber Type: The first consideration when choosing an outdoor drop cable is the type of fiber it contains. The two most common types are single-mode (SM) and multi-mode (MM) fibers. For most residential applications, single-mode fibers are preferred due to their ability to carry data over longer distances with minimal signal loss. Multi-mode fibers are typically used for shorter distances and are more suitable for certain commercial applications.

2.Fiber Count and Capacity: The next step is determining the required fiber count in the drop cable. Consider the current and future needs of the FTTH network, including the number of subscribers and potential expansion plans. Opt for a cable with sufficient capacity to accommodate future demands without requiring extensive upgrades.

3.Cable Construction:Outdoor drop cables are exposed to harsh environmental conditions, including UV radiation, moisture, and temperature fluctuations. As such, the cable construction plays a vital role in its durability. Look for cables with a robust outer jacket made of materials like polyethylene (PE) or low-smoke zero-halogen (LSZH) to ensure resistance against weather elements and reduce the risk of fire hazards.

4.Water-Blocking Features:Moisture ingress is one of the primary reasons for fiber optic cable failure. Choose outdoor drop cables with water-blocking features to prevent water penetration along the cable’s length. These may include gel-filled tubes, water-swellable materials, or dry water-blocking technology, all of which help maintain the integrity of the fiber during adverse weather conditions.

5.Tensile Strength:The outdoor drop cable must be able to withstand pulling forces during installation and maintenance. Check the cable’s tensile strength specifications to ensure it can handle the anticipated stress without compromising signal performance or physical integrity.

6.Bend Radius:Fiber optic cables are sensitive to excessive bending, which can cause signal attenuation and permanent damage. Choose outdoor drop cables with a specified minimum bend radius that adheres to industry standards to protect the fibers during installation and throughout their lifespan.

7.Rodent Protection:In some areas, rodents may pose a threat to outdoor cables. Consider cables with additional rodent-resistant features, such as steel or aramid yarn reinforcement, to safeguard against potential damage.

8.Connector Type:At both ends of the outdoor drop cable, connectors are used to interface with distribution boxes and optical network terminals (ONTs). Common connector types include SC, LC, and FC. Ensure that the chosen cable’s connectors match the equipment used in the FTTH network to guarantee seamless connectivity.

9.Installation Method:Choose between aerial, duct, and direct burial installation methods based on the specific requirements of the FTTH deployment. Aerial cables are suitable for above-ground installations, while duct and direct burial cables are designed for below-ground applications. Consider factors like terrain, accessibility, and local regulations when deciding on the installation method.

10.Standards Compliance: Ensure that the selected outdoor drop cable complies with relevant industry standards such as International Electrotechnical Commission (IEC) and Telecommunications Industry Association (TIA) standards. Compliance with these standards ensures the cable’s performance, reliability, and compatibility with existing network infrastructure.

The FTTH drop cables are used to enable subscriber connections by linking the Optical Distribution Point to the Optical Telecommunications Outlet. Depending on their application, these optical cables are classified into three main categories: outdoor, indoor and outdor-indoor drops. Thus, depending on where they are used within the FTTH infrastructure, optical drop cables must meet a number of performance criteria.

Unlike indoor drops, which are submitted to very few stress after installation, outdoor drop cables must withstand a wide variety of constraints. These optical cables are telecom cables strung alongside telephone poles, used for underground roll-outs and installations into ducts or simply laid or extended alongside facades. To make the right choice in terms of for your network roll-out, it is also important to consider below keys:

1. the most demanding weather conditions for the area where the cable is to be installed. For instance, an aerial cable deployed in an urban sector will not be subject to the same stress as an overhead line installed in a mountain area where snow, frost, falling rocks or hunting accident represent potentiel risks for the network’s integrity.

2. mechanical stress associated with the cable installation in a given geographical area.

Selecting the right FTTH outdoor drop cable is crucial for establishing a robust and reliable fiber optic network. By considering factors such as fiber type, capacity, cable construction, water-blocking features, tensile strength, bend radius, rodent protection, connector type, installation method, and standards compliance, network planners can make informed decisions that lead to optimal performance and longevity. A well-chosen outdoor drop cable will pave the way for high-speed internet connectivity and enhance the overall user experience in the ever-connected world of today.
