PLC Splitter uses a chip to split light. FBT works best for small networks. PLC fits large, complex setups.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Which splitter is better for large networks?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You should choose PLC Splitter for large networks. It supports more outputs and gives you even signal strength. FBT Splitter works well for small, simple networks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does temperature affect both splitters the same way?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You notice FBT Splitter can lose performance in extreme temperatures. PLC Splitter stays stable in hot or cold places. PLC is better for harsh environments.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I use both splitters for different wavelengths?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You get narrow wavelength support with FBT Splitter. PLC Splitter supports a wide range of wavelengths. PLC gives you more flexibility for future upgrades.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Which splitter saves more space in my setup?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You save space with PLC Splitter. It has a compact design and fits tight areas.
