What is a Tunable Laser?
A Tunable Laser is a laser source for which the wavelength can be
varied through a specified range. The Agilent Technologies range of
tunable laser modules also allow you to set the output power, and to
choose between continuous wave or modulated power.
The Agilent Technologies range of compact tunable laser modules are
flexible stimulus modules suitable for applications such as the test of
optical amplifiers, DWDM components, and complete DWDM systems.
Installation
The Agilent 81689A, Agilent 81689B, and Agilent 81649A are front-
loadable modules. For a description of how to install your module,
refer to “How to Fit and Remove Modules” in the Installation and
