Extralink fibre patchcord LC/UPC to SC/UPC, single‑mode G.652D, simplex, 3 mm jacket, 2 m

Extralink fibre patchcord LC/UPC to SC/UPC, single‑mode G.652D, simplex, 3 mm jacket, 2 m is a factory‑terminated single‑mode optical jumper designed for reliable connections between active equipment and passive fibre infrastructure. The cable uses ITU‑T G.652D single‑mode fibre and is terminated with an LC/UPC connector on one end and an SC/UPC connector on the other. With a 3 mm outer jacket and a 2‑metre length, this patchcord is suitable for short interconnects in patch panels, optical distribution frames and equipment interlinks in FTTH and telecom environments.

Advantages

The single‑mode G.652D fibre minimises attenuation and chromatic dispersion over long distances while the simplex construction and precise UPC polish ensure low back reflection and stable optical performance. Compact LC connector on one end and robust SC connector on the other provide compatibility with a wide range of transceivers, converters and patch panels. The 3 mm jacket offers mechanical protection and easy handling during installation and maintenance.

Suitable for

• Connecting optical network equipment (switches, media converters, transceivers)
• FTTH subscriber and distribution links between OLT and ONT/ONU
• Patching between rack-mounted patch panels and terminal enclosures
• Laboratory and testing setups requiring reliable single‑mode connections

Key specifications

• Fibre type: single‑mode G.652D
• Connector A: LC/UPC
• Connector B: SC/UPC
• Configuration: simplex (single fibre)
• Cable outer diameter: 3 mm
• Cable length: 2 m
• Polish type: UPC (ultra‑physical contact)

How to use

Ensure both fibre connectors and adapter ports are clean before mating to avoid increased attenuation or damage. Insert the LC/UPC connector into the corresponding LC adapter or transceiver and the SC/UPC connector into the SC adapter or panel until each connector clicks or seats securely. Route the 3 mm cable gently to avoid sharp bends; maintain bend radii recommended for single‑mode fibres to preserve optical performance. When disconnecting, pull connectors by their housings rather than the cable to prevent strain on terminations.

Recommendations

Use a fibre inspection scope or cleaning tools before installation. For permanent channel installations, verify insertion loss and return loss with appropriate test equipment after connection. Store unused connectors with protective caps and avoid tight bends or crushing of the 3 mm cable during routing and cabinet management.
