1．Variable Optical Attenuator is an important optical passive component in optical fiber communication. It can realize real-time control of signals by attenuating the transmitted optical power.
2．The variable optical attenuator can be combined with optical components such as optical wavelength division multiplexer (WDM), spectroscopic detector (TAP PD), and erbium doped fiber amplifier (EDFA) to form ROADM, VMUX, gain flat EDFA, etc.
3．various types of optical attenuators:SC type,LC type,FC type,ST type ; attenuation values from 1dB to 30dB.
1．Fiber communication on system test
2．Optical passive component test
3．Optical add-drop multiplexer in the optical power regulator
4．Optics lab use
5．Subscriber loop
6．Fiber optical sensor
7．Testing equipment
1．Low back reflection and Low PDL
2．High precision attenuation value
3．Precision control of attenuation range
4．Wide attenuation range
