Storing an FTTH drop cable properly is crucial for maintaining its performance and longevity. As an FTTH drop cable supplier, I understand the importance of providing customers with guidance on how to store these cables effectively. In this blog post, I will share some key considerations and best practices for storing FTTH drop cables.
Understanding FTTH Drop Cables
Before delving into storage methods, it's essential to understand what FTTH drop cables are. FTTH (Fiber to the Home) drop cables are used to connect the main optical network to individual residences or businesses. They come in various types, such as Duct Drop Butterfly Cable, Indoor Outdoor Round Drop Cable, and Figure 8 Indoor Optical Cable. Each type has its own unique characteristics and requirements for storage.
Environmental Conditions
The first and most important factor in storing FTTH drop cables is the environment. Cables should be stored in a clean, dry, and well - ventilated area. Moisture is one of the biggest enemies of optical cables. High humidity can cause corrosion of the cable's metal components and may even lead to water ingress into the fiber, which can significantly degrade the signal quality.
The ideal temperature range for storing FTTH drop cables is between - 20°C and 60°C. Extreme temperatures can cause the cable materials to expand or contract, potentially damaging the fibers inside. For example, in very cold temperatures, the cable sheath may become brittle, making it more prone to cracking. On the other hand, high temperatures can soften the sheath and cause the fibers to shift, leading to signal loss.
Protection from Physical Damage
Physical damage is another major concern when storing FTTH drop cables. Cables should be stored away from sharp objects, heavy machinery, and areas where they may be stepped on or crushed. If the cables are stored in a warehouse, they should be placed on shelves or in racks at a safe height to prevent accidental damage.
When coiling the cables for storage, it's important to use the correct coiling diameter. A too - small coiling diameter can cause micro - bending in the fibers, which can result in increased attenuation of the optical signal. The recommended coiling diameter for most FTTH drop cables is at least 100mm.
Packaging
Proper packaging is essential for protecting the cables during storage. Cables should be stored in their original packaging whenever possible. The original packaging is designed to provide a certain level of protection against environmental factors and physical damage.
If the original packaging is not available, alternative protective packaging can be used. For example, cables can be wrapped in plastic sheeting to protect them from dust and moisture. Additionally, labels should be attached to the cables or their packaging to indicate the type of cable, length, and other relevant information. This makes it easier to identify and retrieve the cables when needed.
Storage in Bulk
For suppliers like me, storing cables in bulk is a common scenario. When storing a large number of cables, it's important to organize them properly. Cables can be grouped by type, length, or customer order. This not only makes it easier to manage the inventory but also reduces the risk of misplacing or losing cables.
In a bulk storage situation, it's also important to ensure that there is enough space between the cables. Overcrowding can lead to entanglement and make it difficult to access individual cables. Moreover, it can increase the risk of physical damage during handling.
Long - Term Storage
If the cables are going to be stored for an extended period, additional precautions should be taken. For long - term storage, it's advisable to periodically inspect the cables for any signs of damage or degradation. This includes checking for changes in the cable sheath, such as cracking or discoloration, and testing the optical performance of the cables.
It's also a good idea to store the cables in a climate - controlled environment. This can help maintain the integrity of the cables over time and ensure that they are in good condition when they are finally installed.
Handling During Storage
Proper handling of the cables during storage is also crucial. When moving the cables, they should be lifted and carried carefully to avoid any sudden jerks or twists. Cables should never be dragged on the floor, as this can cause abrasion to the sheath and damage the fibers inside.
When uncoiling the cables for inspection or installation, it should be done slowly and steadily. Rapid uncoiling can cause the fibers to tangle or break, especially if the cable has been stored for a long time.
Conclusion
Storing FTTH drop cables correctly is essential for ensuring their performance and longevity. By paying attention to environmental conditions, protecting the cables from physical damage, using proper packaging, and following good handling practices, the quality of the cables can be maintained.
