About Maintenance
The connector sections to be cleaned are the key parts, including the tips and sides of ferrules, the interior walls of alignment sleeves and the interior and exterior of connector shells. Note that scratches and particles of foreign matter on the tip of the ferrule can have a disabling effect on fiber-optic transmission. The following procedures should be used when cleaning hybrid fiber-optic camera connectors.
- For Plugs, the interior surfaces of alignment sleeves and the tips of ferrules are to be cleaned with the non-alcohol treated cleaning stick using a gentle stroking action. Canare FCFA and FCFRA enhance easy cleaning procedure for its innovative alignment sleeve and insulator detachable design.
US Patent: No.7241055B2 - For Jacks, it is important to clean both the tips and sides of the completely protruding ferrules with the cleaning stick.
- Both the male and female connector shells tend to attract dust and metal particles, so it is important to clean both the insides and outsides using cotton gauze or similar material.
Dirt on the Tip of the Ferrule / Cladding and Core
Msicrograph of Ferrule End-Face
Finger smear
Caused by the act of mating and de-mating connectors.
Dirt
Adhere when the connector is placed on the floor or dropped.
Alcohol stain
Adhered to dried after cleaning with alcohol without sufficient wiper.
Ferrule & Enlarged View
Cladding that surrounds the core completely is as thin as a human hair. Since optical signals travel through the 10 µm diameter core, which is about 1/3 the size of cedar pollen, even dirt that cannot be seen with the naked eye can be a cause of transmission failures.
Cleaning Procedure
Canare Fiber-Optic connectors enhance easy cleaning procedure for its innovative alignment sleeve and insulator detachable design.
| SMPTE ST 311/304 | Japanese Style | |
|---|---|---|
| 01. Extract an insulator unit.
For FC series, use a removal tool : ASPT -1. OC series does not require special tool. Minus driver or coin should be fine. |
|
 |
| 02. Clean up ferrules.
Canare suggests using CLETOP (photo shown). This stick features ferrule guide for efficient cleaning. For monitoring, a fiber scope will be handy as it displays real time ferrule surface. |
 |
 |
| 03. Dust away on alignment sleeves
Dust also remains on inner part of alignment sleeve. Another end of CLETOP is ideal for wiping inside of alignment sleeve. |
 |
 |
| 04. Put back the unit in place
The right position marked on dots. Insert the unit to the end - click sound. Press again with your finger to make sure properly placed. Insufficient locking may cause an issue - unit remaining on male connector. |
