Advanced aluminum house with good heat Dissipation. Full-GaAs MMIC application with low noise. Digital signal is received -18dBm at lowest and analogy signal -9dBm at lowest. AGC control range: 0 - -9dBm, output level keep unchanged. Low power consumption, high-efficiency switch power can make sure the high reliability and stability of power supply. Power consumption less than 2W. It adopts optical detecting circuit. Multi-stage anti-thunder devices ( transient suppression diode), strictly anti-thunder system to the safe operation of the equipment. Built-in WDM,single-fiber to the home (1490/1310/1550nm) triple-play application can be realized. Built-in isolator can split the two optical waves (1490nm and 1310nm) Output gain adjustable (0-18dB),output level 80dBuV. It can realize the power supply of 5V input port feeding. One output or two outputs. Plug Type:EU Plug,it applies to Indonesia, Germany, France, Spain, Italy and so on.
