428 Series -DWDM Multi-Wavelength Meter
Bristol Instruments
The 428 Series Multi-Wavelength Meter simultaneously measures wavelength, power, and optical signal-to-noise ratio (OSNR) to greater than 40 dB in order to fully characterize DWDM components and DWDM transmission systems.
- Measures wavelength and power of up to 250 optical signals
- Spectral Range: 1270 - 1650 nm (182 - 236 THz)
- Optical wavelength measured to an accuracy as high as ± 0.3 pm
- Continuous calibration with a built-in wavelength standard
- Wavelength accuracy guaranteed to a confidence level of 3δ (≥ 99.6%)
- Automatic calculation of OSNR and channel spacing
228 Series DWDM Single Wavelength Meter
Bristol Instruments
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.
