5.3 Maintenance
The Model 6002/3/4 is designed to perform at specified performance levels. Damaged fiber
cables and dirty connectors are a common source of signal loss or link attenuation. Single mode
optical fibers should be checked frequently. Inspect and test all suspect components to maintain
optimal system performance levels.
As a rule, whenever there is a significant, unexplained light loss, check the fiber cable and the
connectors for potential problems. Remove and inspect optical connectors, be careful not to
damage the fiber end-face surface or the connector housing. Do not force or over tighten the
FC/PC connectors.
Note: It is important to clean the fiber connectors before reinstalling them. Use the protective
dust covers on unused or disconnected components to prevent damage or contamination.
Clean the end-surfaces of fiber cables and connectors with a fiber optics cleaning kit. The ferrules
and end-face surfaces of fiber components must be kept clean and free of contaminants to
function within the established parameters.
Note: Special fiber optics cleaning swabs and lint-free cloth pads saturated with reagent grade
Isopropyl alcohol may also be used to clean optical components.
For additional information on cleaning and connecting fiber optic cables refer to Chapter 2.
Cable management and identification markers should receive a high priority to ensure trouble-
free maintenance tasks. Properly maintained components will assure optimal system operation.
