Page 11: Introduction
What is a Tunable Laser Source? A Tunable Laser Source (TLS) is a laser source for which the wavelength can be varied through a specified range. The Keysight Technologies range of compact TLS modules also allow you to set the output power, and to choose between continuous wave or modulated power. -

[State] parameter in the instrument’s Graphical User Interface, or remotely using GPIB commands. When the ‘Active’ LED is lit the output is enabled. When the active LED is not lit the output is disabled. Keysight 81950A Compact TLS Module Getting Started Guide... -
Page 13: Typical Use Models
Low line width source for complex modulation formats The low line width of the Keysight 81950A Compact TLS module makes this module an ideal light source for transmission systems with (D)QPSK and higher order modulation formats and as local oscillator for coherent receivers. -
Page 14: Optical Output
Getting Started Optical Output Polarization Maintaining Fiber A Polarization maintaining fiber (PMF) output is standard for Keysight 81950A Tunable Laser Source Family. PMF is aligned to maintain the state of polarization. A well defined state of polarization helps ensure constant measurement conditions. -
Page 15: Angled And Straight Contact Connectors
Getting Started Angled and Straight Contact Connectors To ensure most accurate measurements, the Keysight 81950A Fast sweeping Compact TLS module is equipped with angled contact connectors. Angled contact connectors help you to control return loss, since reflected light tends to reflect into the cladding, reducing the amount of light that reflects back to the source. -
