Agilent / HP / Keysight 81657A
81657A Dual Fabry-Perot Laser Source, 1310 nm and 1550 nm, >13 dBm (20 mW)
Description
This Laser Source is a dual wavelength modules to be used in conjunction with optical power meter modules for insertion loss, optical return loss and PDL measurement of broadband components and fiber.
These are insensitive to back reflections and are stabilized for short and long term applications.
For convenience there are single and dual wavelength source modules, available with an output power of up to +13dBm.
The output power of the sources can be attenuated for applications where lower power is needed.
