The AQ220-311A ATTN module is a variable optical attenuator with the low insertion loss, low polarization dependence and high return loss required by variable optical attenuators in optical system testing. By connecting the optional monitor output to the sensor module, programs can be created to precisely control the optical output power.
In addition, the company also provides multiple templates.
Features:
Wide attenuation range:
0 to 60 dB (SM version)
0 to 45 dB (MM version)
Wide wavelength range:
1200 to 1700 nm (SM version)
800 to 1370 nm (MM version)
Applications：
Optical level margin analysis in bit error test
EDFA evaluation test (input level adjustment)
Variable optical attenuator (VOA) evaluation test
Optical output adjustment for stabilizing light source
PD linearity measurement
Transmission loss simulator for optical systems and optical devices
Optical equipment calibration
