Calculate insertion loss for passive optical splitters in PON and distribution networks. Power is divided equally among output ports. Excess loss accounts for manufacturing imperfections, typically 0. A deeper understanding of these. Use 2×N when two inputs feed the same distribution stage. Common values: 2, 4, 8, 16, 32, 64. 5 dB depending on splitter type. By dividing a single optical signal from a central Optical Line Terminal (OLT) into multiple outputs for Optical Network. It is an optical fiber tandem device with many input and output terminals, especially applicable to a passive optical network (EPON, GPON, BPON, FTTX, FTTH etc. ) to connect the MDF and the terminal equipment and to branch the optical signal.
