SMPTE type Connectors
The following explains how to clean Ferrules using a SMPTE type (Lemo 3K series or compatible product) ber cable plug (female)
as an example.
Caution:
When removing the alignment sleeve, be sure to use a dedicated optical contact extractor (DCC.91.312.5LA). Also use the end of the
extractor that has an inner thread.
1
Prepare a dedicated extractor and place the extractor in a position parallel to the connector.
2
Remove the cap of section A (with a thread).
3
Insert the extractor into the alignment sleeve and
turn the extractor clockwise 8 to 10 turns until it
stops. When it stops, pull the extractor out straight.
Leave the alignment sleeve attached to the extractor.
4
Wipe the Ferrule with a cotton swab dampened with
alcohol.
Caution:
- When you wipe the Ferrule, move the cotton swab
straight in a way in which you brush the dust off the
Ferrule. Do not wipe back and forth or in a circle.
Doing so may spread the dirt instead of removing it.
- Do not carelessly blow your breath on the Ferrule.
5
After wiping the Ferrule with alcohol, wipe the
Ferrule with a dry cotton swab.
6
Make sure that the dirt is removed.
Use a loupe to examine the Ferrule.
7
Wipe the electrical contact and alignment sleeve in the same way.
8
Insert the alignment sleeve into the optical contact until it clicks and turn the extractor counterclockwise 8 to 10
turns.
The extractor is removed from the alignment sleeve.
Camera male connectors have neither "top" nor "alignment sleeve" regardless of whether they are receptacles or plugs. For male
connectors, therefore, steps 1 to 3 and 8 above are not required.
