Splitter Terminal Port Ratio
How to Calculate Split Ratio and Insertion Loss? The equation below can be used to estimate the split ratio and insertion loss for a typical split port. Light power goes in and light power coming out of the various legs is reduced in. By dividing a single optical signal from a central Optical Line Terminal (OLT) into multiple outputs for Optical Network Terminals (ONTs) at users' homes, splitters eliminate the need for dedicated fibers to each residence—slashing infrastructure costs while scaling network reach. Optical splitters play an important role in FTTH PON networks where a single optical input is split into multiple output, thus allowing a single PON interface to be shared among many subscribers. 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.
