We then add custom machined gold-plated connectors with precision-polished optical-grade lens surfaces in the connection points for reduced jitter.
Security: The cladding safeguards the fragile fiber Main from exterior mechanical anxiety and humidity. Precision Regulate about cladding dimensions, surface area smoothness, and concentricity is obligatory through the fiber attract method.
