Patchcord SC/APC–SC/APC LSZH Singlemode Extralink G.657.A1 3mm Simplex 30m white

Extralink SC/APC–SC/APC LSZH Singlemode patchcord, 3 mm simplex cable, 30 m length, designed for FTTH and optical network connections. The patchcord uses SC/APC connectors on both ends and G.657.A1 bend‑insensitive singlemode fibre, ensuring reliable signal transmission in installations with limited bending radius. The LSZH (low‑smoke zero‑halogen) outer jacket reduces toxic and corrosive gas emission in case of fire, making the cable suitable for indoor deployments and environments with strict safety requirements.

Advantages

The cable combines SC/APC connector precision with bend‑insensitive G.657.A1 fibre to maintain low insertion loss and stable performance when routed through tight spaces. The 3 mm simplex construction provides a flexible, easy‑to‑manage cable that supports clean connector interfaces and simple termination. The LSZH jacket offers improved fire safety characteristics and minimizes smoke, while the singlemode design supports long‑distance, high‑bandwidth optical links.

Suitable for

• FTTH (fiber to the home) indoor connections
• Patch panels and optical distribution frames
• Equipment interconnects in central offices and server rooms
• Environments requiring low‑smoke zero‑halogen cabling
• Installations with tight bends or restricted cable routing

Key specifications

• Connector type: SC/APC to SC/APC simplex
• Fibre type: singlemode, ITU‑T G.657.A1 (bend‑insensitive)
• Cable diameter: 3 mm
• Jacket material: LSZH (low‑smoke zero‑halogen)
• Cable length: 30 m

How to use

Route the patchcord between devices or from distribution panels to terminal outlets, avoiding sharp kinks and supporting the cable where necessary to prevent strain on connectors. Before connecting, inspect and clean SC/APC endfaces with appropriate fibre cleaning tools to ensure low attenuation. Align the SC/APC connectors into compatible SC/APC adapters or ports until a secure click is felt; avoid excessive twisting or pulling during operation. If re‑routing is required, maintain bend radii recommended for G.657.A1 fibre to preserve optical performance.

Recommendations

Store the cable coiled without sharp bends and protect connector endfaces with dust caps when not in use. For permanent installations, route the patchcord through cable management trays and secure with soft ties to reduce mechanical stress. Use only compatible SC/APC ports and follow standard fibre safety procedures when handling and cleaning.
