Patchcord Extralink SC/APC naar LC/APC singlemode duplex 9/125 µm 3 mm 5 m

Extralink SC/APC to LC/APC Singlemode Duplex patchcord, 9/125 µm, 3 mm diameter, 5 m length, is a factory-terminated optical cable designed for low-loss singlemode connectivity. The cable uses G.657.A1 fibre characteristics and provides full-duplex transmission through SC/APC connector on one end and LC/APC connector on the other. It is suitable for FTTH deployments and connections between optical equipment such as switches, media converters, and ONT/ONU devices where precise alignment and low back-reflection are required.

Advantages

The patchcord combines angled APC terminations with singlemode 9/125 µm fibre to minimise return loss and improve signal integrity in systems sensitive to reflections. Its 3 mm jacket offers mechanical protection and flexibility for rack, patch panel and in-premises routing while keeping bend sensitivity low thanks to the G.657.A1 fibre type. Factory-polished connectors deliver consistent insertion loss and reproducible performance across installations.

Suitable for

• FTTH subscriber connections between OLT and ONT/ONU
• Interconnections between switches, optical transceivers and media converters
• Patch panels and rack-mounted optical distribution frames
• Low-loss singlemode links in data centres and telecom rooms

Key specifications

• Fibre type: Singlemode 9/125 µm, compliant with G.657.A1 bending performance
• Connector A: SC/APC (angled physical contact)
• Connector B: LC/APC (angled physical contact)
• Configuration: Duplex (two fibres)
• Cable diameter: 3.0 mm
• Length: 5 metres
• Usage: Indoor patching and short-distance interconnects

How to use

Route the patchcord following standard fibre handling practices: avoid sharp bends, kinks and excessive tensile stress. Insert SC/APC and LC/APC connectors into the corresponding adapter ports until they click or seat firmly, ensuring the keyed orientation matches the adapter. For duplex links, maintain correct polarity so transmit and receive channels align between devices. Inspect connector endfaces with a fibre inspection tool and clean with approved wipes or solvents if contamination is present before making connections.

Recommendations

Store and install the patchcord in controlled conditions, avoiding temperatures or humidity outside equipment specifications. Use bend radius guidance (typically >30 mm for a 3 mm jacket unless otherwise specified) and protect exposed connectors with dust caps when not in use to preserve low insertion loss and return loss characteristics.
