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.
Wavelength stability of ±0.005 nm or less over a 15-minutes period is achieved using temperature control. The wavelength can be adjusted in a 1.6-nm range.
