Types of OPGW Accessories
Fiber Optic Closures
Fiber optic closures are critical for protecting splice points in OPGW systems. These enclosures safeguard the delicate fiber connections from environmental damage while maintaining serviceability. They are designed for ease of installation and can accommodate various fiber counts, making them versatile for different projects.
Cable Storage Assemblies
Cable storage assemblies are essential for maintaining an organized fiber optic network. They help prevent damage to cables during installation and maintenance, ensuring that every fiber is accessible and protected. These assemblies are especially useful in overhead applications where space and organization are critical for operational efficiency.
Suspension Hardware
Suspension hardware is designed to support the weight of OPGW cables and ensure they are securely attached to transmission structures. This hardware is essential in minimizing stress on the cables due to wind and other environmental factors. Proper selection of suspension hardware based on span lengths and environmental conditions is crucial for the longevity of the installation.
Anchor Hardware
Anchor hardware provides a secure point for OPGW cables to be attached to structures. This is particularly important in areas with high wind or adverse weather conditions. Choosing the right anchor hardware is vital for maintaining the integrity and safety of the cable system over time.
Grounding Accessories
Grounding accessories are used to ensure that OPGW installations are electrically safe. They provide a pathway for fault currents to ground, preventing hazardous situations. This is especially important in high-voltage environments, where grounding can significantly reduce the risk of electrical shocks and equipment failures.
