LoS – Loss Of Signal Or Loss Of Sleep?

For decades Tellabs has promoted fiber cabling usage to all markets. Why? Fiber cabling is amazing! Compared to copper cabling, fiber cabling is lighter, stronger, has higher bandwidth capacity with a longer reach, is less susceptible to interference, is non-corrosive, has a longer life, is more secure while being less expensive.


Now you’re wondering what could possibly be fiber cablings weakest link and what could cause us all to lose sleep at night?


We’ve seen that the majority of Optical Network Terminals sent back for repair had dirty connectors which likely caused network problems such as loss of signal.  The debris, smudging and notching seen in our inspections has been significant.  This is consistent with a study by NTT-Advanced Technology finding that 98% of installers and 80% of network owners experienced connector contamination as the greatest cause of network failure.


Unfortunately, some assume that fiber connectors are clean out of the package and upon removal of dust covers. The truth is you should always inspect, clean and re-inspect all fiber connectors as you build, troubleshoot or replace items in your fiber network. To help, BICSI has a presentation and more detailed installer training that covers proper fiber cable handling. Corning has certifications for fiber installation, design, testing and troubleshooting. You can also find many resources at The Fiber Optic Association. 


Our goal is to help our customers and partners save time, save money and get plenty of sleep by adhering to fiber cabling inspection and cleaning best practices.
