FBT PLC Steel Tube Single Mode Wdm Bandwidth ± 20nm High Isolation
♦ Description:
CWDM is using optical multiplexer to different wavelengths of light to reuse the signals to single fiber transmission, the receiving end of the link, with the aid of photolysis multiplexer to mixed signal in the optical fiber signal is decomposed into different wavelengths, connected to the corresponding receiving equipment.

♦ 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.
