A 1:64 splitter adds ~18dB of insertion loss, leaving less power for attenuation—so it's only viable for short distances (5–10km). PON (Passive Optical Network) is a fiber-based broadband access technology, with core components including OLT, ODN, and ONU. Its single-fiber bidirectional transmission mechanism employs WDM, where downstream traffic adopts broadcast mode (1490nm wavelength), and upstream traffic uses TDMA. Cost Efficiency: A single OLT port can serve 8–64 ONTs via a splitter, reducing the number of OLTs, fibers, and deployment labor needed. The splitter ratio in fiber optic networks refers to how optical power is distributed among the output ports of an optical splitter. 1x32 splits were common in North America for G-PON architectures. in Watts – W), the loss value in dB is calculated by the formula: Loss (dB) = 10 lg ( mW1 / mW2 ) When both gains are equal, the loss is 0 dB, so there is no loss (doesn't happen obviously). If we operate with absolute gains measured in relation to 1. 1x64 and 1x128 split 10GEPON systems Marek Hajduczenia (marek.
