Fiber Optic Adapter LC/UPC Duplex Single Mode (OEM, model ADLC9D)

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
• Mounting: suitable for panel or module installation

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.
