Fiber patchcord Extralink LC/APC - LC/APC Single Mode Duplex 9/125µm G.657.A1 3 m

Extralink LC/APC - LC/APC Single Mode Duplex 9/125µm G.657.A1 3 m is a single-mode fiber patchcord designed for optical links, patch panels and equipment interconnection. The duplex configuration with LC/APC connectors on both ends and a 3 m length enables neat routing between OLT, ONU/ONT, switches and transceivers. The 9/125 µm G.657.A1 fibre specification reduces bend loss, making this cable suitable for FTTH and other installations where tight bends or limited space are expected.

Advantages

The patchcord combines LC/APC angle-polished connectors for low back reflection and reliable mating with standard APC adapters, and a duplex format for two-channel transmission. G.657.A1 single-mode fibre provides improved bend performance compared with standard single-mode fibres, reducing signal loss in constrained routing. The 3 mm cable diameter provides a balance between flexibility and mechanical protection, suitable for rack, panel and outlet connections.

Suitable for

• FTTH subscriber terminations and home installations
• Interconnection of OLT, ONU/ONT and media converters
• Patch panels and distribution frames in telecom closets and data centres
• Connections between fiber transceivers and switches or routers

Key specifications

• Fibre type: Single-mode G.657.A1 (9/125 µm)
• Connector type: LC/APC to LC/APC duplex
• Cable configuration: Duplex, 2 fibers
• Cable outer diameter: 3.0 mm
• Length: 3 meters
• Polish type: Angled Physical Contact (APC) for low back reflection

How to use

Route the patchcord between devices or between a device and a patch panel, avoiding sharp kinks and securing the cable in cable management trays where available. Align LC connectors with the adapter or transceiver receptacle and insert until the latch clicks; ensure the APC end faces match the mating adapter to maintain low return loss. For duplex connections follow the transmit/receive orientation required by the equipment. Do not exceed the minimum bend radius recommended for G.657.A1 fibre and avoid crushing or excessive tensile load on the cable.

Recommendations

Before installation, inspect connector endfaces for contamination and clean with approved fiber cleaning tools if necessary. For FTTH deployments use strain relief at outlets and avoid routing through areas with heavy mechanical stress. Store unused patchcords coiled with gentle loops and protect connector end caps when not connected.
