active repeater

Quick Reference

1 A hardware device that amplifies light signals which travel down a fibre optic communication line. The active repeater receives a light signal and converts it into an electrical signal which is then amplified to full strength and retransmitted as a light signal. This prevents the light signals from becoming weaker and weaker. See also optical repeater.

2 Occasionally used for an amplification device attached to other communications media.
