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.
♦ Feature
- Low Insertion Loss
- High Isolation
- Low PDL
- Compact Design
- Good channel-to-channel uniformity
- Wide Operating Wavelength: From 1260nm to 1620nm
- Wide Operating Temperature: From -40ºC to 85ºC
- High Reliability and Stability

♦ 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.
