Key Connector Types
Each connector family in the iFiber Optix series is optimized for a distinct set of installation environments and performance requirements.
Performance & Applications
Performance Benefits
-
Low Insertion Loss
Precision-ground ferrules and tight dimensional tolerances deliver minimal signal attenuation at every connection point — preserving optical power budget across the full network span.
-
High Return Loss
UPC polish achieves >55 dB return loss; APC variants achieve >60 dB — controlling back-reflected light to protect laser sources and maintain signal quality in sensitive optical architectures.
-
Durable Construction
Connector bodies and ferrules are engineered for rated mating cycles with less than 0.2 dB change over connector lifetime — built to withstand the connection demands of active networks and test environments.
Applications
LC, SC, FC, and ST connectors serve every layer of modern telecom infrastructure — from carrier central offices and outside plant distribution to customer premises equipment and active network nodes.
LC and LC/APC connectors are the standard for high-density patch panels, MDA/HDA structured cabling, and direct transceiver connections in hyperscale and enterprise data center environments.
FC threaded connectors and ST bayonet connectors provide the vibration resistance and mechanical security required for factory automation, process control, and harsh-environment industrial fiber systems.
