1550nm RF-EDFA


Catvision RF-EDFA (Erbium Doped Fiber Amplifier) is specially designed for amplifying weak 1550nm optic signal for long distance optic transmission. Extremely low noise pump lasers ensure excellent C/N, CSO, CTB and maintain picture quality at original levels for long-haul transmission. This can be used for both analog and digital CATV signal transmission. Facility to add local RF channel (Analog or Digital QAM) into the optic signal coming from MSO.

An advanced microcontroller along with automatic control circuit ensures stable optic output power and longer life.
