86120C Keysight multi-wavelength meter

• Maximum number of laser line inputs: 200

• Wavelength range: 1270 - 1650 nm (182 to 236 THz)

• Absolute accuracy ±2 ppm (±0.003 nm at 1550 nm and 1310 nm) with a laser line spacing of 15 GHz

The Keysight 86120C multiwavelength meter family serves as the right optimization tool for efficient development, fabrication, installation, and verification of optical devices and optical networks for next-generation applications. The Keysight multi-wavelength meter is a Michelson interferometer-based instrument that can measure both the wavelength and optical power of a laser in a given wavelength range, as well as multiple laser lines simultaneously, enabling the measurement of DWDM signals and multiple laser lines from Fabry-Perot lasers.

Features.

• Wavelength scan in less than 1 second

• Wavelength accuracy: +- 2 ppm, laser line spacing > 15 GHz

• High laser input power: 10dBm (18dBm - safe input level)

• Built-in HeNe laser wavelength standard

Benefits.

• Wavelength accuracy ensures accurate channel characterization of dense WDM systems to detect channel wavelength variations and adjacent channel crosstalk.

• High input power allows you to perform transmitter testing without additional connections and instrumentation (e.g., attenuators).

• The built-in HeNe guarantees real-time, accurate absolute wavelength measurements according to standards at all times, while ensuring precise and repeatable experimental results.
