81600B Tunable Laser Source Family



                               Data Sheet
Introduction

     The Keysight Technologies, Inc. 81600B Tunable Laser Source Family offers the
     full wavelength range from 1260 nm to 1640 nm with no wavelength gaps. This
     provides test instrumentation with maximum flexibility.

     Investing in the Keysight 81600B Tunable Laser Source Family can realize the
     cost efficiency and performance required to test components for coarse and
     dense wavelength division multiplexing (CWDM, DWDM) and passive optical
     networks (PON).
