3dB Pulse Broadening Solution

STEP 0: Pre-Calculation Summary

Formula Used

3dB Pulse Broadening = sqrt(Optical Output Pulse^2-Optical Input Pulse^2)/(Length Of Cable)
τ_3dB = sqrt(τ_o^2-τ_i^2)/(L₁)
This formula uses 1 Functions, 4 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

3dB Pulse Broadening - (Measured in Decibel per Meter) - 3dB Pulse Broadening is the phenomenon where a well-defined pulse of light becomes broader or stretched out as it propagates through a medium or a transmission system.
Optical Output Pulse - (Measured in Second) - Optical Output Pulse is the measurement of pulse width at output side.
Optical Input Pulse - (Measured in Second) - Optical Input Pulse is the measurement of the pulse widths at input side.
Length Of Cable - (Measured in Meter) - Length Of Cable is the usually the measurement used to measure how long the cable is.

STEP 1: Convert Input(s) to Base Unit

Optical Output Pulse: 12.6 Second --> 12.6 Second No Conversion Required
Optical Input Pulse: 0.3 Second --> 0.3 Second No Conversion Required
Length Of Cable: 2.01 Meter --> 2.01 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

τ_3dB = sqrt(τ_o^2-τ_i^2)/(L₁) --> sqrt(12.6^2-0.3^2)/(2.01)

Evaluating ... ...

τ_3dB = 6.26687963439314

STEP 3: Convert Result to Output's Unit

6.26687963439314 Decibel per Meter --> No Conversion Required

FINAL ANSWER

6.26687963439314 ≈ 6.26688 Decibel per Meter <-- 3dB Pulse Broadening
