Optical Fiber Adapter SC/UPC Duplex SM ADSC9D for 9/125μm Single-Mode Fiber

SC/UPC Duplex SM ADSC9D optical fiber adapter is designed for precise coupling of two 9/125μm single-mode fibers. The adapter provides duplex SC/UPC connections that ensure accurate alignment between mating ferrules for low insertion loss and repeatable optical performance. Compact and mechanically stable, the unit is suitable for panel or chassis mounting in patch panels, splice enclosures, and other structured cabling hardware where reliable single-mode links are required.

Advantages

The adapter offers consistent mating accuracy and low back reflection thanks to SC/UPC end-face alignment. Its duplex configuration supports two independent single-mode channels in a single housing, saving space in telecom racks and distribution frames. The compact form factor and standardized SC interface enable easy installation and replacement, while robust mechanical construction ensures long-term stability in rack-mounted or wall-mounted network equipment.

Suitable for

• Single-mode fiber patch panels and distribution frames
• Data center fiber connections and interconnects
• Telecommunications line terminations and subscriber networks
• Splice enclosures and fiber management systems
• Laboratory testing setups requiring repeatable SC/UPC mating

Key specifications

• Connector type: SC/UPC duplex
• Fiber type compatibility: single-mode 9/125 μm
• Channel count: duplex (2 channels)
• Mounting options: panel or chassis mountable
• Housing: compact rectangular adapter housing for standard SC footprint
• Performance characteristics: designed for low insertion loss and low back reflection with UPC polish

How to use

Install the adapter into the panel or chassis cutout that matches the standard SC footprint and secure it according to the enclosure or patch panel instructions. Insert the SC/UPC connector ferrules of each single-mode patch cord or pigtail into the adapter ports until they click into place, ensuring correct duplex orientation if required. For removal, depress the connector latch and withdraw the connector straight out to avoid damaging the ferrule end face. Maintain clean connector end faces by inspecting and cleaning with appropriate fiber cleaning tools before mating to ensure low loss and reliable performance.

Usage recommendations

Use the adapter with 9/125 μm single-mode fiber only and keep protective dust caps on unused ports. Regularly inspect and clean end faces with lint-free wipes and approved cleaning solutions to maintain low insertion loss. Avoid excessive mechanical stress on connected cables and route fibers to minimize bend radius and strain at the adapter interface.
