The location and arrangement of those splitters determine the network architecture.<\/span><\/p>\n<p><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">The Fiber Broadband Association describes a distributed split as a design in which subscriber addresses are assigned through the built outside plant rather than changed through cross-connect jumpers at a centralized splitter cabinet.

Traditional distributed split<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">In a traditional distributed design, individual splitters are placed at selected outside-plant locations. A splitter may be installed in a splice closure or pedestal and feed nearby terminals or subscriber drops. Because the split point is closer to the served area, the network can use lower-fiber-count distribution cables than a centralized FDH design.<\/span><\/p>\n<p><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">This approach can be suitable where neighborhoods are separated into clear serving areas and where the operator wants to avoid a large centralized cabinet.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Cascaded_or_distributed_cascaded_split\"><\/span><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">2. Cascaded or distributed cascaded split<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">A cascaded design uses two or more splitter stages to reach the final ratio. Common examples include:<\/span><\/p>\n<ul data-spread=\"false\">\n<li><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">1\u00d74 followed by 1\u00d78 for an overall 1\u00d732 split<\/span><\/li>\n<li><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">1\u00d72 followed by 1\u00d716 for an overall 1\u00d732 split<\/span><\/li>\n<li><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Multiple smaller split stages selected for route geometry and subscriber density<\/span><\/li>\n<\/ul>\n<p><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">The first splitter divides the PON signal among several routes. A second splitter\u2014often integrated into a local MST\u2014then serves homes near the terminal. This reduces the number of fibers required along long distribution routes and allows smaller cables to serve dispersed subscriber clusters.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Unbalanced_split_or_optical_tap_architecture\"><\/span><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">3. Unbalanced split or optical tap architecture<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">An optical tap network uses splitters with unequal power outputs along a route. Part of the optical power serves subscribers at one location, while the remaining power continues downstream to additional tap terminals.<\/span><\/p>\n<p><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">This approach can be highly fiber-efficient for linear routes and low-density areas, but it requires careful optical engineering. Tap values, distance, connector loss, and downstream subscriber count must be planned so that every ONT remains within its permitted receive-power range.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_Operators_Choose_Distributed_Splitting\"><\/span><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Why Operators Choose Distributed Splitting<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Lower_distribution_fiber_count\"><\/span><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Lower distribution fiber count<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Centralized splitting typically requires a dedicated distribution fiber from the FDH toward each subscriber position. Distributed splitting allows one feeder or distribution fiber to reach a local splitter that serves multiple homes, reducing fiber count along the route.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Smaller_outside-plant_cables\"><\/span><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Smaller outside-plant cables<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Lower-fiber-count cables can reduce cable diameter, weight, and space requirements. This can be valuable where existing conduits have limited capacity or where aerial pole loading and cable congestion are important considerations.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Reduced_dependence_on_large_FDH_cabinets\"><\/span><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Reduced dependence on large FDH cabinets<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Distributed designs use closures, pedestals, and terminals placed throughout the network.
