The AQ2200-111 is a DFB-LD module for the AQ2200 series. It can be used in a wide range of applications, including tests on various optical characteristics in creating a virtual network on an optical fiber network.
The AQ2200-111's optical output port consists of an angled PC connector, and it contains an internal isolator to suppress reflective light. This design provides excellent level stability of ±0.005 dB over a 15-minute period.
Optical output can be adjusted in the range of 0 to 10 dB (in steps of 0.01 dB) while maintaining a fixed wavelength. Levels can be adjusted between WDM signal channels.
The DFB laser's spectral width can be set to WIDE or NARROW. During loss measurements, the WIDE setting suppresses interference and makes it easier to obtain accurate measurements.
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.
