## Long description

OEM LC/UPC Duplex Single Mode fiber optic adapter (model ADLC9D) provides a compact and precise coupling solution for two LC/UPC single-mode connectors. Designed to align ferrules accurately, this adapter ensures low insertion loss and consistent optical performance for telecom and data network links. Its duplex format supports paired fiber connections in patch panels, fiber modules and active equipment that require LC duplex terminations, enabling straightforward integration into existing cabling infrastructure.
Advantages
The LC/UPC Duplex adapter delivers stable mechanical alignment and repeatable optical contact for single-mode fibers. Its compact duplex housing reduces panel space while maintaining reliable coupling between LC male connectors. Constructed to meet common optical network requirements, the adapter provides consistent insertion loss and return loss characteristics expected for UPC-polished interfaces, and its simple push-pull operation facilitates quick insertion and removal during maintenance.
Suitable for
Patch panels and fiber distribution frames
Fiber optic modules and chassis
Data center and telecom backbone links
Fiber-to-the-office or fiber-to-the-desk duplex runs
Equipment requiring LC duplex single-mode terminations
Key specifications
Connector type: LC/UPC duplex
Fiber type: single mode
Adapter format: duplex, inline/mountable
Polish type: UPC (ultra-physical contact)
Typical insertion loss: low (measured per industry practice)
Return loss: optimized for UPC interfaces
Compatibility: standard LC single-mode ferrules

How to use
Install the LC/UPC Duplex adapter into the panel cutout or module slot designed for duplex adapters. Align the adapter body so that both adapter ports are accessible, then insert LC/UPC male connectors until they click into place, ensuring proper seating. For removal, depress the connector latch and gently withdraw the connector. Observe standard fiber handling precautions: keep ferrule endfaces clean, avoid excessive bending of fiber cables near the connector, and perform optical loss testing after installation to verify link performance.
Usage recommendations
Regularly inspect and clean connector endfaces with approved fiber cleaning tools before mating to maintain low insertion loss. Use dust caps on unused adapter ports to prevent contamination, and verify connector type compatibility (LC/UPC single-mode) before installation. For critical links, perform OTDR or power-meter testing to document insertion loss and continuity after installation.
