Optical Wavelength Meter

Optoplex Optical wavelength meter (OWM) uses proprietary thin-film interference filter in conjunction with Fabry-Perot cavity technology combined with a micro-actuator and high-speed electronics. Its working principle is schematically shown below. By comparison with Optical channel monitor / Optical performance monitor, the proprietary wavelength reference unit is introduced to ensure high precision wavelength measurements. Optoplex Optical wavelength meter is the only DWDM wavelength meter capable of measuring wavelengths of multi-lasers in DWDM networks over C-band and L-band wavelength range with a high accuracy better than that the wavelength locker can provide. For example, the device can simultaneously report 80 wavelength values of 80 channels at 50 GHz channel spacing with the wavelength accuracy ± 2 GHz. DPRAM, RS-232, or USB interfaces are available and OWM can be customised to meet specific requirements.
