Product Description
1310/1550nm MEMS polarization-maintaining tunable attenuator VOA with FC connector
The MEMS polarization-maintaining tunable attenuator is a high-performance optical attenuator based on microelectromechanical systems (MEMS) technology, specifically designed for polarization-maintaining fiber systems. This product precisely controls the attenuation of optical signals while preserving the polarization state of the input light, making it widely applicable in fiber optic communication, fiber optic sensing, and optical measurement fields.
Feature:
- steel tube type small package
- Low insertion loss, low wavelength-dependent loss/polarization-dependent loss
- Fast response time
Use:
- optical power control and equalization
- Wavelength Division Multiplexing (WDM) system
- GAIN CONTROL OF EPOLED FIBER AMPLIFIER
