Fibre optic cable Extralink EX.14862 20 m FTTH G.652D SC–SC full duplex yellow

Extralink EX.14862 is a 20 m FTTH fibre optic cable designed for short single-mode connections. The cable uses G.652D single-mode fibre and is factory-terminated with SC connectors on both ends in a full duplex SC–SC configuration. It is intended for fiber-to-the-home installations, patching and linking networking equipment such as switches, media converters, OLTs and ONUs/ONTs where a ready-made 20 metre single-mode link is required.

Advantages

This pre-terminated 20 m patchcord reduces installation time and eliminates on-site termination. The use of G.652D fibre ensures compatibility with common single-mode systems and long-distance transmission standards. Full duplex SC–SC termination provides separate transmit and receive paths for reliable bidirectional connectivity, while the yellow outer jacket aids quick identification of single-mode cabling in installation environments.

Suitable for

• FTTH subscriber connections between OLT and ONU/ONT
• Patching and linking switches or media converters in single-mode networks
• Short-distance single-mode backbone or lateral links within wiring closets
• Test setups and lab environments requiring a 20 m SC–SC duplex link

Key specifications

• Fibre type: single-mode G.652D
• Connector type: SC–SC full duplex (SC/APC on one end and SC/UPC on the other as supplied)
• Length: 20 metres
• Cable diameter: 3 mm
• Jacket colour: yellow (single-mode identification)
• Application: FTTH, patching, linking networking equipment

How to use

Inspect connector end-faces for cleanliness before connecting and, if necessary, clean with appropriate fibre cleaning tools. Route the 20 m cable along cable management paths, avoiding tight bends and pinch points; maintain bend radius recommended for single-mode optical fibre. Insert the SC connectors into the corresponding SC ports of the devices, ensuring correct orientation and secure latching for both transmit and receive channels to establish full duplex communication.

Recommendations

Store unused cable coiled without tight loops and protect connector end caps when not connected. For best optical performance, keep connector end-faces clean and avoid kinking the 3 mm cable; observe typical single-mode handling practices during installation and maintenance.
