Extralink LC/UPC-LC/UPC Single Mode Duplex Patchcord 1 m, G.652D, PVC, 3 mm

Extralink LC/UPC-LC/UPC Single Mode Duplex Patchcord 1 m is a precabled optical jumper designed for single-mode networks. It features LC/UPC connectors on both ends and uses G.652D single-mode fibre within a 3 mm PVC-jacketed duplex cable. Built for full-duplex links, this 1 m patchcord is intended for use in FTTH networks, patch panels, optical transceivers and other short interconnects in telecom and data centre environments.

Advantages

The patchcord provides low insertion loss and stable single-mode transmission thanks to G.652D fibre and precise LC/UPC terminations. Its 3 mm PVC jacket offers mechanical protection and ease of handling while maintaining flexibility for routing in racks and enclosures. The duplex configuration ensures correct polarity and simplifies full-duplex connections between equipment such as OLTs, ONTs, switches and SFP transceivers.

Suitable for

• FTTH subscriber connections between OLT and ONU/ONT devices
• Patch panel connections in telecom and data centre racks
• Short interconnects between optical transceivers and switches
• Laboratory and test bench single-mode fibre measurements and setups

Key specifications

• Fibre type: ITU-T G.652D single-mode fibre
• Connector type: LC/UPC on both ends, duplex
• Cable diameter: 3 mm
• Jacket material: PVC
• Length: 1 metre
• Configuration: Full-duplex

How to use

Verify connector polishing (UPC) and ensure connectors and ports are clean before mating to minimize reflection and insertion loss. Align LC connectors with the corresponding LC ports on patch panels, transceivers or customer-premises equipment and insert until a light click confirms engagement. Maintain correct duplex polarity when connecting transmit and receive channels. Avoid tight bending of the cable near connectors; follow recommended minimum bend radius for single-mode cables to preserve optical performance.

Recommendations

Store and handle the patchcord in a dry, dust-free environment. Use dust caps when connectors are not in use and perform regular optical cleaning with appropriate fibre cleaning tools. For permanent or outdoor runs, select cables with suitable jackets or additional protection; this PVC-jacketed 3 mm patchcord is intended for indoor installations and short interconnects.
