Patchcord Extralink SC/APC - SC/UPC single-mode duplex, G.652D fiber, 3 mm, 15 m

Patchcord Extralink SC/APC - SC/UPC single-mode duplex, G.652D fiber, 3 mm, 15 m is a 15 metre single-mode duplex fiber optic cable designed for reliable point-to-point connections between optical devices. It uses G.652D single-mode fiber and is terminated with an SC/APC connector on one end and an SC/UPC connector on the other, assembled in a 3 mm jacket suited for indoor FTTH and equipment interconnects. The cable provides full-duplex transmission with standard SC connector form factor for use in backbone links, patch panels and direct device connections.

Advantages

The Extralink patchcord combines G.652D single-mode fiber with industry-standard SC connectors for low attenuation and predictable propagation characteristics. Its SC/APC to SC/UPC termination minimises back reflection on the APC side while maintaining compatibility with UPC-terminated equipment. The 3 mm jacket offers mechanical protection and easy handling during installation without excessive stiffness, and the 15 m length covers medium-distance runs between racks, switches, converters and FTTH termination points.

Suitable for

• FTTH drop and indoor subscriber connections between OLT and ONU/ONT
• Interconnecting optical equipment such as switches, media converters and patch panels
• Backbone and horizontal fiber links inside buildings and data closets
• Laboratory and testing setups requiring a duplex SC/APC–SC/UPC link

Key specifications

• Fiber type: single-mode G.652D
• Connector type: SC/APC to SC/UPC duplex
• Cable diameter: 3 mm
• Length: 15 m
• Transmission mode: full-duplex
• Typical application: indoor FTTH and equipment interconnect

How to use

Route the patchcord avoiding sharp bends and mechanical stress; maintain the cable bend radius recommended for 3 mm single-mode cables. Insert each SC connector squarely into the corresponding SC adapter or port until it clicks to ensure secure connection. Use the APC-terminated end where low back reflection is required and connect the UPC end to equipment ports expecting UPC ferrules. For best optical performance, inspect connector endfaces with a fiber inspection tool and clean with appropriate fiber cleaning materials before mating.

Recommendations

Store the cable coiled without tight loops and protect connector endfaces with caps when not in use. Avoid running the patchcord parallel to high-voltage power lines for long distances and keep away from sources of mechanical abrasion. For critical links, verify insertion loss and return loss with an optical power meter or OTDR after installation.
