Repeater

alt text

A Repeater is a network device used to regenerate and amplify signals in order to extend the distance a network can cover without data loss. It operates at the Physical Layer (Layer 1) of the OSI model.

Functions

  1. Signal Amplification – Boosts weakened signals to restore them to their original strength.
  2. Extends Network Range – Allows data to travel farther over a network medium without degradation.
  3. Error Reduction – Minimizes data corruption caused by signal loss over long distances.

Common Usage

  • Commonly used in coaxial cable networks and some fiber optic or wireless links.
  • Typically, a maximum of four repeaters can be used in a single cable network segment to avoid excessive latency and signal distortion.
