INSTALLATION
OPTICAL CONNECTORS AND CLEANING
The standard optical connector is an SC/APC. The fiber ends can be damaged by the insertion of
contaminated connectors. Some types of customer damage to connectors or fiber are not covered under warranty.
Fiber connectors should never be left uncovered. Reel cleaners or prepackaged alcohol wipes are the most
convenient means of cleaning optical connectors. Clean alcohol and lint free wipes or swabs may also be used.
