Fusion splicing and termination are essential technologies used in outdoor optical fiber distribution boxes to connect and manage fiber optic cables. Here’s an overview of these technologies:
1.Fusion Splicing: Fusion splicing is a process of permanently joining two fiber optic cables together by melting and fusing their glass fibers. In outdoor distribution boxes, fusion splicing is commonly used to create reliable and low-loss connections. The process involves aligning the fiber ends, applying heat to melt the fibers, and then fusing them together. Fusion splicing provides a robust and permanent connection that offers low insertion loss and high reliability.
2.Fusion Splicing Equipment: Fusion splicing requires specialized equipment, including fusion splicers. These devices precisely align and fuse the fiber ends. Fusion splicers typically have an arc discharge system that generates heat to melt the fibers and optical alignment systems to ensure accurate alignment. They also have advanced features such as fiber cleaving mechanisms, automated fusion programs, and splice loss estimation capabilities.
3.Mechanical Splicing: Although less common in outdoor distribution boxes, mechanical splicing is an alternative method that uses mechanical connectors to join fiber optic cables. Unlike fusion splicing, mechanical splicing does not require melting and fusing the fibers. Instead, it uses alignment structures and mechanical clamps to secure the fiber ends together. Mechanical splicing is relatively quicker and simpler than fusion splicing, but it may result in slightly higher insertion loss.
4.Termination Techniques: Termination involves connecting fiber optic cables to connectors or devices within the outdoor distribution box. Several termination techniques are commonly used, including:
5.Connectorization: This technique involves attaching fiber optic connectors to the ends of the fiber cables. Connectors are pre-polished and pre-terminated components that provide quick and reliable connections. Common connector types include SC, LC, ST, and MPO/MTP connectors.
6.Pigtail Splicing: In this technique, a short length of fiber called a pigtail is fusion spliced to the incoming fiber cable. The other end of the pigtail is terminated with a connector for easy connection to other devices or equipment within the distribution box.
7.Field-Installable Connectors: These connectors are designed to be terminated in the field without the need for fusion splicing. They often feature mechanical or epoxy-based termination methods that can be performed on-site, providing flexibility and convenience during installations or repairs.
8.Cable Management: Proper cable management is essential in outdoor distribution boxes to organize and protect fiber optic cables. Cable management techniques include using cable trays, splice trays, cable ties, and slack storage to maintain proper bend radii, minimize stress on the cables, and facilitate future maintenance and troubleshooting.
