81640A keysight Tunable Laser Source

Overview

Manual

Wavelength range: 1510nm to 1640nm
Maximum output power: 4dBm
Wavelength accuracy (absolute value): ±0.015nm
Wavelength repeatability (typical): ±0.5pm

The keysight 81640A tunable laser source covers both the C- and L-bands. It is specially designed for testing critical DWDM passive components.

The keysight tunable laser source marked "A" has been replaced by the 81640B, but can be upgraded.

Features

Operates in both DWDM wavelength bands (C and L bands)
Continuous scanning over the entire wavelength range
Low source spontaneous emission output with high dynamic range
Optical amplifier test high power fiber output
Built-in real-time wavelength table
Mode-hopping-free adjustment over the entire wavelength range
Both fiber outputs are equipped with Panda-type polarization maintenance fiber
