EXFO IQS-12004B DWDM Passive Component Test System for IQS-500 - Manual (Page 19)

Introducing the IQS-12004B DWDM Passive Component Test System
DWDM Passive Component Test System 7
Tunable Laser Source

EXFO has modified its IQS-2600B Tunable Laser Source in order to
integrate it into the IQS-12004B DWDM Passive Component Test System. To
optimize the performance of the system, the optical attenuator which
ensures a constant power output from the tunable laser source has been
removed.
You can easily identify which tunable laser source you have. The unit
designed for the DWDM Passive Component Test System bears the
mention 2600CT, while the standalone unit bears the mention 2600B.
Every customer purchasing the IQS-12004B DWDM Passive Component
Test System for applications covering both the C- and L-bands will receive
an IQS-2600CT model. Even though the tunable laser source has been
modified, it can still be used as a standalone instrument using an IQS-500
Intelligent Test System.
However, you will notice a warning message when turning the instrument
on. This warning informs you that the automatic level control (ALC) is
disabled. Also note that the power stability and repeatability values
presented in the IQS-2600B specification sheet do not apply to the
IQS-2600CT.
Any other functionality or specification, particularly those concerning the
accuracy of the instrument and wavelength stability, will not be affected by
this design change.
