Keysight 86122C Multi-Wavelength Meter

Overview

The Keysight 86122C is a precision multi-wavelength meter designed for developing, manufacturing, and verifying tunable transmitter lasers and optical subsystems in high-speed communication applications. With absolute wavelength accuracy of ±0.2 ppm and differential accuracy of ±0.15 ppm, it operates across the fiber-to-the-home, metro, and long-haul transmission spectrum. The instrument can measure up to 1,000 laser lines simultaneously, supporting fully populated dense-wavelength-division multiplexed (DWDM) systems.
