PLC splitters offer excellent channel uniformity, high stability over temperature, and consistent optical performance, making them well suited for large-scale and standardized network architectures.<\/p><p data-start=\"3286\" data-end=\"3629\">Because every output port experiences similar attenuation, equal splitters are easy to model during the network planning phase. This simplicity is one of the main reasons they are widely used in urban FTTH networks, apartment buildings, and office complexes where subscribers are densely distributed and fiber distances are relatively similar.<\/p><p data-start=\"3631\" data-end=\"3997\">That said, equal splitting can become a limitation when deployment conditions are less uniform. In short-distance scenarios with small split ratios, ONU receivers may experience relatively strong input signals.

These values make unequal splitters particularly useful when optical power needs to be preserved for downstream distribution.<\/p><p data-start=\"4713\" data-end=\"5000\">Unequal splitters are most commonly produced using <strong data-start=\"4764\" data-end=\"4806\">FBT (Fused Biconical Taper) technology<\/strong>. Compared to PLC, FBT manufacturing allows more flexible control of split ratios by adjusting the fiber fusion and tapering process.

In rural or suburban deployments where users are spread along roads or across large geographic areas, a single feeder fiber can serve multiple access points sequentially. By tapping a small portion of the signal at each location and allowing the majority of the power to continue downstream, service providers can significantly reduce the number of feeder fibers required.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0455ee3 elementor-widget elementor-widget-heading\" data-id=\"0455ee3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Split Ratio, Power Budget, and ONU Receive Levels<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-47d61a4 elementor-widget elementor-widget-text-editor\" data-id=\"47d61a4\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p data-start=\"5544\" data-end=\"5764\">Regardless of splitter type, all FTTH designs must operate within a defined optical power budget. Each <a href=\"https:\/\/yfconnectivity.com\/what-is-an-optical-network-unit\/\"><strong>ONU<\/strong><\/a> has a specified receive power range, and maintaining signals within this window is critical for stable operation.<\/p><p data-start=\"5766\" data-end=\"6117\">If excessive splitting or long fiber distances push attenuation too high, the ONU may experience increased bit error rates or intermittent service loss. Conversely, insufficient attenuation\u2014often seen in short-distance networks with low split ratios\u2014can result in receiver saturation, which affects signal quality and may impact long-term reliability.<\/p><p data-start=\"6119\" data-end=\"6386\">Unequal splitters provide network designers with additional flexibility to balance these constraints.

This means that <strong data-start=\"6670\" data-end=\"6705\">OTDR traces become more complex<\/strong>, and fault localization requires a clearer understanding of the network topology and expected attenuation at each point.
