The AQ2200-312 is a variable optical attenuator type for the AQ2200 series. When it is installed in an AQ2200 series frame controller, it allows optical output to be attenuated to any value.
The AQ2200-312 ATTN module is a variable optical attenuator capable of adjusting optical output with high precision over the wavelength range of 1200 nm to 1700 nm (SM version). The ATTN module’s output can be varied in steps of 0.001 dB over a wide attenuation range of 0 to 60 dB (SM version). In addition, this attenuator provides the low insertion loss, low polarization dependence, and high return loss needed in a variable optical attenuator for optical system test. With the optional monitor output connected to a sensor module, it is possible to create programs to precisely control the optical output power.
Multi-mode version is also available.
This system does not require manual reconfiguration of optical paths and adjustments of EDFA input power, and that improves measurement throughput and avoids a human error.
