LTEDFA-1550-5 Outdoor 4 ports EDFA Optical Amplifier

Overview        LTEDFA-1550-5 series outdoor optical amplifier, is designed in accordance with GY / T 184-2002 "cable television system analog fiber amplifier technical requirements and measurement methods" standard. The use of internationally renowned brands of constant-frequency constant-temperature pump, low noise, saturated output power and high stability, can be used for cable television images, digital TV signals, telephone voice signals and data signals in long distance and large area. It is a preferred product for outdoor optical transmission system.
       LTEDFA-1550-5 series of outdoor optical amplifier has great features as low noise, low power consumption, structural optimization, high reliability and so on. It is applied in the wavelength of 1550nm fiber optic transmission system. The built-in high-performance microprocessor can monitor the pump working state and input / output optical power in real-time. When the fiber amplifier is not working properly, it will indicate the corresponding alarm information and makes a serious alarm. It will automatically shut down the pump laser to protect the device. When there is not optical input, it will automatically shut off the pump.
       The built-in RF detection port, detecting the front-end RF signal parameter, greatly improves the site maintainability. Features         Use of imported high-performance constant-temperature DFB laser module, fully guarantee the excellent link performance.
        The use of high-performance microprocessors, display module parameters and status monitoring in real-time.
        The excellent APC and ATC circuit, to ensure the stability of the device.
        The perfect protection circuit (working parameters alarm, real-time when optical power is too high or too low).
        excellent machine thermal design, to ensure the long-term reliability of the equipment.
        output optical power adjustable, adjusting range -3dB ~ +0.5 dB.
        With RF detection port, easy to maintain. Technical Specifications
