Range
The multi-channel single-mode 0~40dB optical attenuator is an
important optical communication instrument, which has multiple
channels and can achieve accurate attenuation of optical signals in
the range of 0 to 40dB. Here is a detailed description of the
product:
Product characteristics
Multi-channel design: Support multi-channel optical signal
attenuation, the number of channels can be customized according to
customer needs, up to 32 channels.
Single-mode fiber support: Designed for single-mode fiber, it is
suitable for optical signals with wavelength lengths of 1260-1650nm
(including the commonly used 1310nm and 1550nm).
Attenuation range and accuracy: the attenuation range can reach
0-40dB, the attenuation step is usually 0.1dB, and the attenuation
stability is within ±0.04dB, ensuring high-precision optical signal
regulation.
High performance indicators: with low insertion loss, high return
loss (usually greater than 55dB), high stability and optical power
balance, etc., to ensure the quality and efficiency of optical
signal transmission.
Flexible customization: The connector type and tail length can be
customized according to customer requirements to meet the
requirements of different application scenarios.

Working principle
The working principle of the multi-channel single-mode 0~40dB
optical attenuator is mainly based on the attenuation mechanism of
the optical signal in the transmission process, including light
absorption, light scattering, light reflection and attenuation
technology based on optical fiber dislocation or displacement. By
controlling these mechanisms, the optical signal intensity can be
precisely adjusted.
Application field
Telecommunications industry: Used in optical fiber communication
networks to regulate the power of optical fiber signals, prevent
excessive signal strength from causing damage to the optical fiber
system, and protect the normal operation of the system.
Network industry: In the network signal transmission, by adjusting
the signal power, improve the stability of network equipment and
transmission quality.
Television broadcasting industry: In the transmission of broadcast
signals, the signal power is adjusted to protect the broadcast
system from interference caused by excessive signal strength.
Safety industry: In the safety equipment, by adjusting the signal
power, to prevent the system from generating noise due to too
strong signals, improve the safety and stability of the system.
