Extralink PATCHKABEL LC/UPC-SC/APC SM G.657A1 DUPLEX 3.0MM 2M

The Extralink PATCHCORD LC/UPC-SC/APC SM G.657A1 DUPLEX 3.0MM 2M is a 2-metre single-mode duplex fibre optic patchcord intended for FTTH and point-to-point optical connections. It combines LC/UPC and SC/APC terminations to provide full-duplex transmission between equipment such as switches, media converters, OLT and ONU/ONT devices. The cable uses G.657.A1 fibre, which maintains low loss while offering improved bend performance for installations in compact or confined routing paths.

Advantages

This patchcord offers a standardized duplex interface with mixed LC and SC connector types to support a range of optical ports. The single-mode G.657.A1 fibre provides reliable signal integrity over long runs while being more tolerant of tight bends compared with standard single-mode fibres. The 3.0 mm jacket balances flexibility and mechanical protection, making the cable suitable for both patch panel and wall outlet use.

Suitable for

• FTTH connections between OLT and ONU/ONT equipment
• Interconnection of switches, media converters and optical transceivers
• Patch panel ports and wall-mounted fibre outlets in residential or small-business installations
• Environments with tight routing or limited bend radius

Key specifications

• Fibre type: single-mode G.657.A1
• Cable configuration: duplex
• Cable outer diameter: 3.0 mm
• Length: 2 metres
• Connector types: LC (UPC) and SC (APC) terminations

How to use

Connect the LC and SC connectors to corresponding ports on optical equipment, ensuring correct orientation for UPC and APC terminations. Route the cable to avoid excessive bending and secure it with appropriate cable management accessories. For FTTH use, plug one end into the customer premises ONU/ONT and the other into the provider’s OLT or distribution point as required by the installation layout.

Recommendations

Avoid tight bending beyond the specified bend radius of G.657.A1 fibre, and keep connector end-faces clean using lint-free wipes and approved fibre cleaning tools. Inspect connectors for damage before insertion and store the patchcord coiled without sharp kinks when not in use.
