14.2.  Cleaning DLX connector and adapter

14.2.1.  DLX connector cleaning

14.2.1.1. Clean both the optical port adapter and the 

drop cable connector (requires accessory kit FHD-ACC-

CLNKIT1) as specified in ADCP-96-163.  

 
14.2.1.2. Examine the end of the drop cable connector, 

note the position of the protrusions on the connector. 

14.2.1.3. Locate the cleaning tape cassette that is 

provided with the cleaning kit.

14.2.1.4. Open the tape shutter by squeezing the lever 

on the underside of the cassette and then keep the shut-

ter open by continuing to squeeze the lever. 

14.2.1.5. Hold connector facing you with the protrusions 

perpendicular to the length of the cleaning cassette, tilt 

the connector to the right (no more than 8-degrees) this 

places the connector in the correct position for cleaning. 

 

Note: 

The drop cable connector uses angled SC type 

connectors. Make sure the connector end-face is point-

ing in the correct direction before starting the cleaning 

motion

. 

14.2.1.6. With light pressure, slide the connector end-

face once across the tape in the direction shown using a 

smooth linear motion. Do not press too hard and do not 

repeat the cleaning motion with the same tape. 

14.2.1.7. Release the lever on the underside of the cas-

sette to close the tape shutter. 

14.2.1.8. Repeat Step 11.4.2.3 through Step 11.4.2.6 until 

the connector has been cleaned three times. 

14.2.1.9. When the connector and the adapter are clean, 

install the connector into optical port.

14.  Maintenance

The maintenance of the indexing terminal installation 

includes cleaning :

14.1.  HMFOC cleaning

14.1.1.  Inspect the complete multi fiber ferrule on the 

adapter side as well as on the connector side with a low 

resolution microscope as specified in IEC 61300-3-35 

with floodlight  (side illumination). If dirt is detected, follow 

cleaning instructions below.  

14.1.2.  CommScope recommends dry cleaning first 

with a tool such as the US CONEC IBC brand cleaning 

tool - MT Series (PN 15639). Follow the cleaning instruc-

tions included with the tool.
14.1.3.  To clean the connector on the tail (female, plug, 

non-pinned) place the blue plug adapter on the end of the 

tool, align the keys of the tool and the connector, rotate 

the thumb wheel clock wise two ‘clicks’. 

14.1.4.  To clean the adapter on the terminal (male, 

jack, pinned) place the red plug adapter on the end of the 

tool, align the keys of the tool (slot) and the adapter 

(square notch), rotate the thumb wheel clock wise two 

‘clicks’.

 

14.1.5.  If dry cleaning does not produce the desired 

results, use a small amount of solvent on one or more 

Chemtronics ® Covenrty ™ 2.5mm fiber optic swabs. 

A non isopropyl alcohol (IPA) solvent is recommended 

(such as Chemtronix PX Wash). Using the swabs, re-

move contaminates/dirt from the ferrule end face. Always 

use a new swab for each connector. 

14.1.6.  If there is a need to moisten a connector end 

face, it must be blown dry with clean compressed air, 

then dry clean the connector as detailed described in step 

14.1.2 untill step 14.1.4. 

14.1.7.  After cleaning, inspect the multi fiber ferrule on 

adapter and connector side again.
