Splitter Ratio Calculator -

Example: You need 10mW out of a 100mW source on Port 1. k = 10/100 = 0.1 (10%). Coupling loss = -10 * log10(0.1) = 10dB (The main port loses 10dB). Tap loss = -10 * log10(0.9) = 0.45dB (The tap port loses 0.45dB).

The splitter ratio is critical in telecommunications because it directly affects the performance of the signal distribution system. A well-chosen splitter ratio ensures that: splitter ratio calculator

Problem: You have a TV antenna on the roof. The main house TV is 10 feet from the splitter. The security gatehouse is 800 feet away via buried RG11 cable. Challenge: If you use a standard 50:50 splitter, the gatehouse will get almost no signal (800ft loss ~ 40dB). The house TV will be overloaded. Calculator Solution: Input cable lengths and required receive power. The calculator outputs: Use a 95:5 asymmetrical tap. 95% (0.2dB loss) goes to the gatehouse to fight the long cable run; 5% (13dB loss) goes to the nearby house. Example: You need 10mW out of a 100mW source on Port 1

These are glass fibers fused together. They are temperature sensitive but cheap for low port counts (1x2, 1x4). Tap loss = -10 * log10(0

The (for the port receiving less power) is: Tap Loss (dB) = -10 * log10(1 - k)
