What Network Owners and Operators Need to Know About Fiber Testing

Certification of an FTTH network confirms proper installation before customers start using it. That means fewer service problems and easier routes to modifications. It also gives comfort to those who financed the build. Fiber test equipment makes testing and certification easy – often easier than for copper wiring. Network testing and certification should be part […]

Wofür wird ein OTDR benötigt?

Was ist ein OTDR? Ein OTDR ist ein Glasfasertester zur Charakterisierung von optischen Netzwerken, die Telekommunikationsanwendungen unterstützen. Die Aufgabe des OTDRs besteht darin, Netzelemente an beliebigen Positionen einer Glasfaserstrecke zu erkennen, zu lokalisieren und zu messen. Hierfür muss das OTDR nur an einem Ende der Strecke angeschlossen sein, da es wie ein eindimensionales Radarsystem funktioniert. […]
