Introducing the IQS-2600B Tunable Laser Source
Tunable Laser Source 3
IQS-2600CT Tunable Laser Source for IQS-12004B DWDM Passive Component Test System
IQS-2600CT Tunable Laser Source for
IQS-12004B DWDM Passive Component Test
System
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 IQS-12004B, the optical attenuator
ensuring a constant power output from the tunable laser source has been
removed.
You can easily identify the type of tunable laser source you have. The unit
designed for the IQS-12004B system will bear the mention 2600CT, while
the stand-alone unit will bear 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 stand-alone instrument using an IQS-600
Integrated Qualification System. However, you will notice a warning
message when turning the instrument on.
This warning informs you that the power output is not monitored and
cannot be controlled internally. 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.
