Why should clean EYDFA amplifier’s optical connector & adapter?
When the EYDFA amplifier is turned on, it generates a lot of power at the port connector. If the connector is dirty, the fiber connector end may burn. If the port connector is broken, the power port drops, causing the whole optical link to lose redundancy, the optical power to the subscriber is not enough, and performance suffers, as well as EYDFA amplifier’s optical adapter.
How to clean EYDFA amplifier’s optical connector?
CAUTION:
ALWAYS MAKE SURE that all power is removed from PL2000x EYDFA amplifier before optical connectors are connected.
Use caution when handling fibers. Do not exceed fiber manufacturers’ pulling tension or bend radius specifications when removing the fiber bulkhead connector plate.
Remove the fiber connector dust cap and wipe the fiber connector tip with a high-quality fiber cleaner or dry lint-free cloth. Check if there are scratches or debris on the connector surface using a fiberscope.
If no scratches or debris are found, the connector is clean and ready for connection.
If debris or scratches are found, then repeat the cleaning of the fiber patch cord connector.
How to clean EYDFA amplifier’s Optical Adapter?
Compressed air can be used to clean the fiber optic adapter. Compressed air with at least the following specifications.
Non-residue, inert gas for precision dust removal
Ultra-filtered to < 0.2 microns
Recommended for optical systems
Using compressed air as listed above, remove the adapter dust cover and hold the can of compressed air about 6 inches from the connector. After spraying a few short bursts into the adapter, the connector was clean and ready for connection.
If compressed air is not available, the fiber adapter connector can be cleaned by a 2.5 mm cotton swap or the connector plate may be removed to clean the internal fiber patch cords.
After EDFA connector cleaning, we can start EDFA connection setting up.
- Clean all fiber patch cords before connecting.
- Make sure the laser key switch on the front panel of the transmitter is in the OFF position.
- Connect a fiber patch cord from the output of the transmitter to the optical power meter, turn key ON position of transmitter laser. Be sure the optical output is in the -10~+10dBm range (0dBm is recommended).
- Turn switch key of transmitter to the OFF position and power OFF.
- Connect the fiber patch cord to the amplifier input. Power up that transmitter once the fiber connections to the amplifier input are secure.
- Turn the transmitter laser key switch to the ON position.
