Definition of Terms Specifications
Agilent 81600B Tunable Laser Source Family, Fourth Edition 41
Mode-hop free tunability
Specifies the wavelength range for which no abrupt wavelength change
occurs in “Stepped mode”. Abrupt change is defined as change of more
than the specified “Absolute wavelength accuracy (stepped mode)”.
Operating temperature and humidity
The ambient temperature range and humidity range of the tunable laser
source for which the specifications apply.
Output isolation
The insertion loss of the built-in isolator in the backward direction.
Measurement: This characteristic cannot be measured from outside the module. It is
based on known isolator characteristics.
If the optical mainframe hosting the tunable laser source module is
rack-mounted
the temperature and humidity within the rack apply.
