Latiguillo de fibra óptica Extralink EX.3630, 0,5 m, G.657.A1, SC a LC, FTTH, dúplex, amarillo

Extralink EX.3630 is a 0.5 m single-mode FTTH patch cable that uses ITU-T G.657.A1 fibre for reduced bend sensitivity. The cable is duplex and terminated with an SC connector on one end and an LC connector on the other, providing a compact SC-to-LC connection suitable for short-distance links and equipment patching. Designed for access networks, ONT and OLT connections, and internal rack or cabinet patching, this patch cord supports reliable single-mode optical transmission where low-bend loss and space-efficient terminations are required.

Advantages

The G.657.A1 fibre reduces sensitivity to tight bends, allowing installation in confined spaces and around sharp edges without significant signal loss. Duplex configuration enables full-duplex transmission over a single cable run. The combination of SC and LC connectors offers compatibility with a wide range of optical equipment while the short 0.5 m length helps manage patching inside distribution panels and server racks. The cable’s yellow jacket identifies it as single-mode, simplifying cable management.

Suitable for

• FTTH subscriber connections between OLT and ONT/ONU
• Short-distance patching in telecom racks and distribution panels
• Interfacing equipment with SC and LC ports in access networks
• Laboratory setups and test benches requiring short duplex single-mode links

Key specifications

• Fibre type: single-mode G.657.A1 (low-bend loss)
• Length: 0.5 m
• Configuration: duplex
• Connectors: SC (one end) to LC (other end)
• Cable diameter: approximately 3.0 mm
• Jacket colour: yellow (single-mode)

How to use

Identify the SC and LC ports on your devices and align the connectors with the corresponding receptacles. Gently insert the SC connector until it latches, and insert the LC connector until it clicks into place. Route the cable to avoid excessive tensile load or sharp bends beyond the fibre’s minimum bend radius even though G.657.A1 offers improved bend tolerance. For duplex connections observe transmit/receive pair orientation to ensure correct full-duplex operation.

Recommendations

When installing, avoid pulling the cable by the connectors and secure the cable near patch panels or equipment using appropriate tie points. Use dust caps when connectors are not in use. For permanent installations maintain bend radii recommended for G.657.A1 fibres and avoid repeated flexing at connector ends to preserve long-term optical performance.
