Is the following description correct? The key parameters of ODN network are attenuation, insertion loss, and return loss.

Question

Options

• ATrue
• BFalse

• A
  80% (41)
• B
  20% (10)

Explanation

Option A is correct because attenuation, insertion loss, and return loss are the three fundamental parameters used to characterize and evaluate an Optical Distribution Network (ODN). Attenuation measures the total signal power loss as light travels through the fiber over distance, insertion loss quantifies the additional power loss introduced by passive components such as splitters, connectors, and splices, and return loss measures the amount of signal reflected back toward the source at connection points, which can degrade transmission quality if too high. Option B is incorrect because dismissing any one of these three parameters would leave the ODN characterization incomplete -- all three are necessary to assess link budget, component quality, and overall network performance.

Memory tip: Think "AIR" -- Attenuation (path loss), Insertion loss (component loss), Return loss (reflection loss). All three measure how signal power is affected in different ways as it travels through the ODN.
