1b - Cleaning the DLS 355
The DLS 355 laser source is a high-end test laser, capable of outputting 1310 and 1550nm
wavelengths. The output port of this unit utilizes a physical connection, which means that it
can become soiled if used improperly. When needed, the DLS 355 adapter may be removed for
inspection and cleaning of the fiber ferrule.

DLS 355 is stored with
adapter ON to protect
ferrule inside.
Remove adapter by
unscrewing until it spins
freely, then pull off.
Inspect ferrule with
VIS 300C and clean
with appropriate tools.
Always replace adapter.
Regular inspection and cleaning of the output port of the DLS 355 may not be necessary if
appropriate procedures are followed. Always inspect test jumpers before they are plugged into
the DLS 355 and store it properly to ensure continued performance.
