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 FTTH cabling solution for your network roll-out, it is important to consider:
1. Understand the Requirements: Before selecting a drop cable, understand the specific requirements of your FTTH project. Consider factors such as the distance between the distribution point and the customer premises, environmental conditions, and the number of fibers needed.
2. Fiber Type: Determine the type of fiber required for your application. Single-mode fiber is typically used for long-distance transmission, while multi-mode fiber is suitable for shorter distances. Choose the appropriate fiber type based on the distance and bandwidth requirements of your network.
3. Cable Construction: Select a drop cable with appropriate construction for outdoor installation. Look for cables designed to withstand outdoor environmental conditions such as UV exposure, moisture, temperature variations, and mechanical stress. Typically, outdoor drop cables have a durable outer sheath made of materials like polyethylene (PE) or polyvinyl chloride (PVC).
4. Fiber Count: Consider the number of fibers required for your FTTH network. Choose a drop cable with a sufficient number of fibers to accommodate current needs and allow for future expansion if necessary.
5. Bend Radius: Pay attention to the minimum bend radius of the drop cable. Ensure that the cable can be safely routed around corners and obstacles without exceeding the specified bend radius, which can lead to signal loss or damage to the fiber.
6. Connector Compatibility: Check the compatibility of the drop cable connectors with the connectors used in your network equipment and customer premises equipment (CPE). Ensure that the cable connectors are compatible with industry-standard connectors such as SC, LC, or ST.
7. Installation Method: Consider the installation method for the drop cable. Choose between aerial, buried, or underground installation based on your specific requirements and local regulations. Select a drop cable that is suitable for your chosen installation method.
8. Quality and Reliability: Prioritize quality and reliability when selecting a drop cable. Choose cables from reputable manufacturers with a track record of producing high-quality fiber optic products. Look for cables that comply with relevant industry standards and certifications.
9. Cost Consideration: While cost is an important factor, prioritize performance and reliability over price when selecting a drop cable. Investing in high-quality, durable cables can help prevent future maintenance costs and ensure long-term network performance.
10. Consultation and Expertise: If you're unsure about which drop cable to choose, consider consulting with fiber optic experts or network engineers who can provide guidance based on your specific requirements and project constraints.
By considering these factors and conducting thorough research, you can choose the most suitable FTTH outdoor fiber drop cable for your project, ensuring reliable performance and durability in outdoor environments.
