By Wendy Sutton / CommScope A s demand for bandwidth continues to increase, the migration to all-fiber networks will dominate network deployment decisions. Although fiber was used originally in just trunk networks, the ever-increasing demand for bandwidth soon made it the future-proof carrier in feeder, distribution and drop parts of access networks for both business and residential customers. Looking forward, the bandwidth and latency requirements for 5G and the internet of things will further increase the number of fibers and optical passive devices in access networks, as will the convergence of wireless backhaul and wireline access networks. e lifestyles and economies of today and the future will strongly rely on this next-generation fiber communications utility grid. A critical component of successful fiber networks in the outside plant is the fiber splice closure. Used to connect fiber cables, such closures serve two functions: 1 Organizing the overlength of exposed fiber strands and optical connections 2 Protecting fiber strands from the external environment. However, use of the closures is not a one-size-fits-all proposition. Each part of the network has specific challenges and requirements. Making the wrong closure choice impacts cost, labor needs, quality of service and network migration readiness. Trunk: As the main link between large, central offices, a trunk segment must, above all, remain reliable. Directly impacting a broad audience, closures in the trunk connect equipment over a long distance, utilizing cables with a high volume of fibers accessed by only highly skilled technicians. In principle, this is an "install and forget" situation, and re- accessing the closures is exceptional. Fibers are often mass spliced and organized in the most compact way possible. Feeder: Branching out from central offices toward large business customers and thousands of end users, feeder cables are accessed more frequently than those in the trunk segment. In the 1990s, when fiber was being rolled out in the feeder segment, service providers needed a solution to avoid interrupting service for large business customers Commscope fiber closures for FTTH and other applications
