 A Quick Start Guide to Fiber-to-the-Antenna (FTTA) Installation and Maintenance Testing
Inspect Before You Connect
Contamination is the  source of troubleshooting in optical networks! 
A single particle mated into the core of a fiber can cause significant back reflection (return loss), insertion loss, and 
equipment damage. Visual inspection is the only way to determine if fiber connectors are truly clean before  
mating them.

By implementing a simple yet important process of proactive visual inspection and cleaning, poor optical signal 
performance and potential equipment damage can be avoided. Network failures can be significantly minimized by 
up to 80%.
