♦ 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 (TVS transient suppression
diode), strictly anti-thunder system to ensure 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 8V input port feeding.
♦ One output or two outputs.
