Extralink patchkabel LC/UPC-LC/UPC singlemode duplex G652D 3mm 20m

The Extralink Patchcord LC/UPC-LC/UPC Single Mode Duplex G652D 3mm 20m is a 20‑metre fiber optic patch cable designed for FTTH and professional single‑mode networks. Constructed with ITU‑T G.652D compliant single‑mode fiber and duplex LC/UPC terminations on both ends, the cable provides low insertion loss and stable optical performance for interconnecting switches, media converters, OLT and ONU/ONT equipment. The 3.0 mm outer diameter jacket offers a balance of flexibility and protection for indoor and controlled‑environment installations.

Advantages

This LC/UPC‑LC/UPC patchcord uses G.652D single‑mode fiber that is compatible with standard single‑mode systems and minimizes dispersion over long distances. Duplex LC connectors provide a compact, industry‑standard interface that supports high‑density patch panels. The 3 mm round cable construction improves handling during routing and reduces microbending sensitivity, while factory‑terminated polished UPC connectors ensure consistent optical contact and repeatable performance.

How to use

Install the patchcord by gently routing it between devices and through cable management pathways, avoiding sharp bends (minimum bend radius typically 10× cable diameter) and excessive pulling force. Plug the LC connectors into compatible duplex adapter ports or transceiver modules until they click into place. When disconnecting, depress the connector latch and pull straight out without twisting. Keep protective dust caps on unused connectors to maintain endface cleanliness and optimal signal quality.

Recommendations

For reliable long‑term performance, clean connector endfaces before installation using appropriate fiber cleaning tools and follow manufacturer guidelines for handling fiber optic cables. Use color‑coded routing or labels to distinguish duplex pairs and document connection points in patch panels.
