ПРОДУКЦИЯ описание: DW-EDFA55PA is a most practical adjustable power amplifier, this machine adopt international famous brand of the pump laser and the United States OFS erbium doped fiber, has low noise, saturated output power, improve the reliability of the APC, ACC, ATC control and good ventilation and heat dissipation design, to ensure the pump laser and the whole life a stable job, through the front panel buttons to adjust the output optical power, regulating range every 0.1dBm, 3.0dBm down. The input optical signal is lost, the laser automatic closing, the pump laser itself play a good role in the protection, applicable to the central office, branch and line relay, can also be used for other optical fiber communication network, CATV system is the most commonly used, the most dosage is a fiber amplifier. This machine is equipped with a microprocessor software, has a laser monitoring, digital display, fault alarm, network management and other functions, once the machine working parameters deviate from the software set the permission scope, the flashing red lights, warning.
