Hangzhou Hengchi Electronic Equipment Co.Ltd was established in 2006, produce and sales equipments of optical transmitter, EDFA, optical receiver, optical switch, optical node , OLT, ONU and so on.
What is an EDFA Optical Amplifier?EDFA optical amplifier, also known as erbium-doped fiber amplifier, is a kind of special fiber with the rare earth element erbium injected into the fiber core. It was first developed by the University of Southampton in 1985. Since the late 1980s, the research of EDF
In recent years, the excellent performance-price advantage of 1550nm externally modulated optical transmitter technology has come to the fore as optical device production technology has improved and prices have fallen. With 14 years of experience in designing and manufacturing complex fibre optic an
CATV Optical amplifier is a device that can directly amplify optical signals without first converting them into electrical signals. An optical amplifier can be thought of as a laser without an optical cavity, or a laser with feedback from the cavity suppressed. Optical amplifiers are very important
