The Agilent/Keysight 86122B Multi-Wavelength Meter delivers precise wavelength measurement across the 1270–1650 nm band for optical component and subsystem verification. This re-engineered successor to the 86122A maintains backward compatibility while supporting modern computing environments and 24/7 testing operations with minimal downtime. The instrument resolves up to 1000 laser lines and characterizes tunable transmitter lasers and optical subsystems critical to high-speed telecommunications and photonics development.
