Cabo de patch Extralink SC/UPC – SC/UPC monomodo duplex, fibra G.652D, 3 mm, 20 m

The Extralink SC/UPC – SC/UPC single-mode duplex patchcord is a 20 m optical jumper designed for low-loss single-mode links. It features SC/UPC connectors on both ends and uses G.652D fibre within a 3 mm FTTH-style cable construction to provide stable full-duplex transmission. The cable is intended for optical networking, telecom links, FTTH installations and laboratory setups that require predictable single-mode performance and simple SC connector compatibility.

Advantages

This patchcord delivers consistent single-mode performance with low insertion loss thanks to G.652D fibre and UPC-polished SC connectors. The duplex format supports simultaneous transmit and receive channels over two fibres, simplifying full-duplex connections. The 3 mm jacket offers improved mechanical protection and ease of handling during installation compared with bare or microcables. Its standardized SC/UPC interface ensures broad compatibility with common optical equipment and patch panels.

Key specifications

How to use

Route the patchcord along cable trays, ducts or cable managers avoiding sharp bends and excess tensile stress. Insert each SC/UPC connector into the corresponding SC adapter or port until it clicks, observing correct polarity for transmit and receive channels. Verify continuity and optical loss with appropriate test equipment after installation. For repeated connections, keep protective dust caps on unused connectors and clean end faces before mating.

Recommendations

Keep bending radius above the minimum specified for single-mode fibre, clean connector end faces with suitable fiber cleaning tools before each connection, and avoid pulling the cable by the connectors to maintain long-term link quality.
