1 32 Splitter Transmission Distance
A 1:32 splitter divides input power by ~32 (adding ~15dB of insertion loss), so the remaining power supports signals up to 20km. For example, a 1:32 splitter may cause about 15-17 dB loss. Environmental Factors: Fiber bends, temperature, and humidity may also contribute. A typical split ratio in a PON application is 1:32, meaning one incoming fiber split into 32 outputs. If the distance between the OLT and ONU of your network is short, such as 5 km, you can also. 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. 47 Billion USD in 2020 and is expected to grow at an average rate of 5.
