Splicing and termination in FTTH systems are critical for establishing reliable optical connections. It provides mechanical protection, environmental sealing, and internal fiber management for spliced optical fibers. Whether extending fiber connections, repairing damaged cables, or integrating new components, choosing the right technique can make a significant difference in signal integrity and overall. These enclosures play a vital role in protecting spliced fiber optic cables from environmental hazards such as moisture, dust, and extreme temperatures, ensuring long-term durability and optimal performance. Some common types include dome splice closures, inline splice closures, and horizontal splice closures.
