General Maintenance
Aside from the AC input fuse, there are no user serviceable parts in this product. If you suspect something has
failed in the unit, please contact Thorlabs for advice on returning the unit for evaluation.
Always clean fiber optic connectors that will be inserted into the system and install the dust cap whenever the source
is not being used. Allowing dust and dirt onto the fiber end faces will degrade coupling efficiency and possibly
damage the fiber patch cables, both inside and outside.
9.1.
Cleaning
The housing can be cleaned using a soft, slightly damp cloth. Avoid using any solvents on or near the unit. Keep
the vent holes on the sides, rear and bottom of the enclosure free of dust buildup. Restricted airflow will cause the
temperature controls to operate inefficiently and, in extreme cases, loss of temperature control.
9.2.
Connector Cleaning
Always clean the ferrule end of your fiber patch cables as well as the input and output FC bulkheads prior to inserting
the fiber patch cables into the FC bulkheads. Thorlabs offers the FCC-7020 Fiber Cleaning Cloth Spool, which can
be used for cleaning the ferrule ends of the patch cables.
Additionally, each unit is shipped with an FBC250 Bulkhead and Connector Cleaner for cleaning the input and
output bulkheads.
