Latiguillo Extralink SC/UPC - SC/APC, monomodo G.657.B3, LSZH 3mm simplex Easy Flex, 20 m

Singlemode Extralink patchcord with SC/UPC connector on one end and SC/APC on the other, designed as a 20 m simplex cable for low-bend-loss applications. The fibre meets G.657.B3 profile requirements and is installed inside a 3.0 mm diameter cable with an LSZH (Low Smoke Zero Halogen) jacket and Easy Flex construction. This patchcord is suitable for fiber access, subscriber connections and inter-equipment links where a flexible yet robust singlemode connection is required.

Advantages

The Extralink SC/UPC–SC/APC patchcord combines low-bend-loss G.657.B3 fibre with a slim 3 mm LSZH jacket to provide reliable optical performance in tight routing paths. Easy Flex cable construction improves handling during installation and reduces stress on connectors, while the mixed connector pair (SC/UPC to SC/APC) enables compatibility with equipment requiring different end-face polish types. The LSZH outer sheath limits smoke and toxic fumes in the event of fire, making the cable suitable for indoor environments and confined spaces.

Suitable for

• FTTH subscriber drops and indoor subscriber patching
• Interconnection between OLT, ONU/ONT and optical equipment
• Tight bend routing in cabinets, conduits and behind walls
• Signal distribution in buildings where low-smoke materials are required

How to use

Verify connector types on the equipment before installation to ensure SC/UPC and SC/APC terminations match the intended ports. Route the patchcord along planned pathways avoiding sharp bends and mechanical pinch points; the G.657.B3 fibre tolerates tighter radii than standard singlemode cable but still requires careful routing. Insert connectors into corresponding adapter ports until a positive click is felt for secure mating. When disconnecting, press the connector latch and pull straight out to avoid lateral stress. Clean connector end-faces with appropriate fibre cleaning tools before making connections to maintain low insertion loss and good optical performance.

Recommendations

Store the patchcord coiled with a large radius and avoid repeated tight bending. Use dust caps on unused connectors and perform end-face inspection and cleaning before each connection. In environments with fire-safety requirements, prefer LSZH cabling and follow local installation standards for routing and support.
