catv trunk amplifier
Optical amplifier is an significant device deployed for optical communication and laser physics. No need for converting optical signals into electrical signals first, optical amplifier can directly amplify the optical signals. It is considered to be a laser without optical cavity or with suppressed feedback from cavity. Optical amplifiers are often installed at places where optical signals are weak and need to be enhanced. This ensures the stable transmission of optical signals in the rest cables.
