Notice
Wavelength meter slot module of FOTS system offers two main functions of an accurate wavelength meter and a precise tunable band-pass filter. This accurate instrument, which is based on an internal tunable filter, acts as an optical spectrum analyzer or a wavelength meter as well as a low insertion loss tunable filter. The built-in tunable filter of the module is precisely tuned in C-band and L-band optical communication window by using both electronic and optical controlling methods. User can choose the function of this module depending on his or her applications.

Keysight Technologies
The Keysight 10717A Wavelength Tracker tracks changes in the air's index of refraction to optically compensate for environmental changes. It uses one axis of a laser measurement system to report wavelength of light changes, not changes in position. It is used to correct displacement values reported by other measurement axes in the system, hence improving measurement accuracy. It provides a higher degree of accuracy than environmental sensors such as the 10751C and 10751D Air Sensors.

Optoplex Corporation
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 customized to meet specific requirements.
