Accessing the Receiver/Transmitter Module Fiber Spool and Connector
Optical receivers and transmitter modules have an integrated fiber spool inside the
module housing. This allows the fiber pigtail to be spooled up and contained within
the module housing.
You may need to access this spool to clean or replace a fiber pigtail or connector.
Follow this procedure to access the module fiber spool and connector.
1 Pull up on the two module cover knurled tabs. Use a slight rocking motion.
Note: If the module is out of the housing, it is easier to hold the module in both
hands and push up on the two module cover knurled tabs with your thumbs.
You can also insert a flat blade screwdriver into the cover release tab slot on the
right side of the module housing to assist with opening the cover.
The module cover opens as shown.
2 Pull the fiber connector straight out from the side of the module cover to remove
it.
3 Disassemble the fiber connector and pigtail for cleaning if necessary.
