The new 228 Series Optical Wavelength Meter from Bristol Instruments combines high accuracy and exceptional repeatability to achieve the most meaningful results for DWDM test applications.

The model 228 is the ideal instrument for precise wavelength characterization of tunable DWDM lasers, DFB lasers, and VCSELs. It can also be used to calibrate passive DWDM component test equipment such as optical spectrum analyzers.

Features:

• Spectral Range: 1250 - 1650 nm (240 - 182 THz)
• Sensitivity: -30 dBm (1 W)
• Absolute optical wavelength measured to the highest accuracy of ± 0.3 pm
• Continuous calibration with a built-in wavelength standard
• Optical wavelength measured to a confidence level of 3σ (≥ 99.6%) Simultaneous measurement of total optical power
• Measurement time as short as 0.1 s
