Fibre optic cable Extralink EX.16309 20 m, FTTH G.657.A2, SC–SC, green/white

Extralink EX.16309 is a 20 m FTTH single‑mode patch cable with G.657.A2 fibre and SC–SC terminations. Designed for indoor fibre‑to‑the‑home routing, the cable combines a 3 mm diameter flexible jacket with low‑smoke, halogen‑free (LSOH) material and SC connectors on both ends to provide reliable, low‑loss optical links between equipment, patch panels and terminal devices. The G.657.A2 fibre specification ensures improved bending performance for installations with tight routing or constrained spaces.

Advantages

The cable offers enhanced bend resistance thanks to G.657.A2 single‑mode fibre, reducing signal loss in tight radii. Its 20 m length and 3 mm compact jacket make it suitable for longer indoor runs while remaining easy to handle and route. SC–SC connectors provide standardized, durable terminations for common FTTH equipment. The LSOH outer sheath reduces toxic gas emission in the event of fire, making the cable suitable for indoor installations where safety requirements apply.

Key specifications

How to use

Route the patch cable between the two optical ports to be connected, ensuring connectors are clean and free of dust before insertion. Gently insert the SC connectors into the corresponding adapter or device port until they click into place. Avoid sharp bends and maintain the minimum bend radius recommended for G.657.A2 fibre where possible to preserve optical performance. For splicing or panel termination, use the cable as a pre‑terminated patchcord or as a temporary lead during commissioning.

Recommendations

Inspect and clean connector endfaces with appropriate fibre cleaning tools before each connection. Do not exceed manufacturer‑recommended bend radii or apply excessive tensile load during installation. Use cable management accessories and strain relief at termination points to prevent microbending and ensure long‑term reliability.
