Single-channel single-mode multi-mode optical attenuator in one machine
Single-channel single-mode multi-mode optical attenuator is a device that integrates the functions of single-channel optical attenuator and multi-mode optical attenuator in one, which is suitable for testing, calibration and debugging of optical communication systems.
Product characteristics
High-precision control: The use of advanced optical technology and materials can achieve accurate control of the optical signal strength. This kind of high precision control helps to achieve more stable signal transmission and higher transmission quality in optical communication systems.
Multi-mode compatibility: The design takes into account the transmission characteristics of multi-mode optical signals, which can be compatible with different modes of optical signals and effectively attenuate them. This makes the all-in-one machine have a wider range of applications in optical communication systems.
Integration and miniaturization: The single-mode and multi-mode optical attenuators are integrated into one, small size, easy to carry and use. At the same time, the integrated design also helps to reduce the overall cost and complexity of the device.
High stability and reliability: The internal use of high-quality optical materials and structures, after strict testing and screening, to ensure that the equipment can maintain stable performance in harsh environments. In addition, the device also has good anti-interference ability, which can maintain stable signal transmission in complex optical communication environment.

Benchtop optical attenuator is a high precision and wide range optical power attenuator. A new data acquisition and processing method is adopted, which has a larger signal-to-noise ratio, faster response speed, and can reach a large continuous tunable dynamic attenuation range of 0 ~ 60 dB.
Benchtop optical attenuators are primarily used for channel balancing, power balancing, gain slope, and power adjustment in DWDM systems, as well as for optical measurement and applications of AWG & PLC components, optical amplifiers, and other general-purpose fibers.
