procedures other than those specified herein may result in hazardous 
radiation exposure.
 
 
Avoid personal injury! The laser light source on this equipment emits 
invisible laser radiation. Avoid direct exposure to the laser light source.
 
 
Avoid personal injury! Viewing the laser output with optical instruments 
(such as eye loupes, magnifiers, or microscopes) may pose an eye hazard.
 
1  Insert a dry bulkhead swab into the bulkhead and rotate the swab several times. 
2  Remove the swab and discard. Swabs may be used only once. 
3  Check the bulkhead optical surface with a fiber connector scope to confirm that it 
is clean. If further cleaning is needed: 
a  Moisten a new bulkhead swab using a lint-free wipe moistened with 
optical-grade (99%) isopropyl alcohol. 
b  With the connector removed, fully insert the bulkhead swab into the 
bulkhead and rotate the swab several times. 
c  Remove the swab and discard. Swabs may be used only once. 
d  Check with a fiber connector scope again to confirm that there is no dirt or 
alcohol residue on the optical surface. 
e  If any alcohol residue remains, clean it off with a new dry bulkhead swab. 
4  Mate all connectors to bulkheads and proceed to Verifying Equipment 
Operation below. 
5  It is also recommended that all connectors be visually inspected after cleaning to 
verify the connector is clean and undamaged. 
Verifying Equipment Operation 
Perform circuit turn-up. If the equipment does not come up, i.e., fails verification or 
indicates a reflection problem, clean the connectors and bulkheads again.
