Dry F/O Cleaning Procedure 6.10.2
CAUTION
! Invisible laser radiation might be emitted from disconnected Fibres or
connectors. Do not stare into beams or view directly with optical
instruments.
PRUDENCE!
rayonnement laser invisible peut être émis à partir de fibres ou les
connecteurs débranchés. Ne pas regarder en faisceaux ou voir directement avec des
instruments optiques.
1. Before cleaning the SFP connectors it is advisable to clean the connector of the mating cable being
attached to the optical port.
An unclean optical connector is often the cause for reduced system performance. A bit of dust or oil
from a finger can easily interfere with, or block light. Fortunately, it is very easy to clean the connector.
Be sure to use the correct procedure for the given connector. When disconnected, cap the SC/APC
connector to keep it clean and prevent scratching the tip of the ferrule.
Use a product specially designed for the purpose,
such as the Cletop type S Cassette Cleaner.
2. Begin by dry cleaning the F/O bulkhead connector (shown below is the Fujikura One-Click in use).
IMPORTANT! Always make sure there is a way of inspecting the connector
after cl
eaning. Cleaning can actually leave the end-
face in a worse condition, since
alcohol residue is one of the most difficult contaminants to remove.
IMPORTANT!
Assurez-vous toujours il y a une façon d'inspecter le connecteur
après le nettoyage. Le nettoyage peut en réalité laisser l'extrémité
-
face dans un
état pire, car le résidu d'alcool est l'un des contaminants les plus difficiles à
éliminer.
