1550nm Optical amplifier LTEDFA-1550-2

Overview        LTEDFA-1550-2 series optical amplifier for CATV, is designed in accordance with GY / T 184-2002 "cable television system analog optical amplifier technical requirements and measurement methods" standard. It has low noise, high gain, structural optimization, high reliability and other characteristics. This optical amplifier is used in optical fiber transmission systems of wavelength 1550nm working window. The Built-in microprocessor can monitor the pump working status and input / output optical power and other parameters in real-time. When the optical amplifier is mal-functioning, the corresponding alarm information will be output. When a serious alarm (including the input optical signal is too low or no optical signal is inputted), the pump laser is automatically turned off to protect the optical amplifier. This Equipment has small size, high reliability, easy to operate, support the Chinese interface, use international standard network management standard protocol, directly monitor the status and fault diagnosis through the Ethernet.
