Fiber Patchcord Extralink SC/UPC–SC/UPC Simplex G.657.A2 single-mode 20m

Fiber Patchcord Extralink SC/UPC–SC/UPC Simplex G.657.A2 single-mode 20m is a single-mode fiber optic jumper designed for indoor use. It features SC/UPC connectors on both ends in a simplex configuration and uses G.657.A2 bend-insensitive fiber. The flat drop design and 20-metre length suit connections in patch panels, FTTH terminations and direct equipment links where low insertion loss and stable single-mode transmission are required.

Advantages

This patchcord offers bend-insensitive G.657.A2 fiber which reduces attenuation in tight routing and confined spaces. The SC/UPC connectors provide a reliable physical contact for single-mode links and are compatible with standard SC ports. The flat drop profile eases routing under cable management systems and along walls, while the 20 m length allows flexible placement of network devices without adding splice points. The product is intended to deliver consistent low-loss performance for indoor optical connections.

Suitable for (tasks / use cases)

When it may not be suitable

This fiber patchcord is intended for indoor single-mode applications and may not be suitable for outdoor or direct-burial installations where additional armoring, UV resistance or environmental protection is required. It is also not appropriate for multimode equipment or systems that require different connector types or duplex cabling.

Key specifications

How to use

Route the flat drop cable along the planned path, avoiding sharp bends and tight knots despite the bend-insensitive design. Clean connector endfaces with appropriate fiber cleaning tools before insertion to minimize insertion loss and reflections. Insert the SC/UPC connectors into matching SC ports until they click into place. For removal, depress the connector latch and pull straight out to avoid stressing the fiber. Store excess length neatly in cable management trays or coil loops with a gentle radius.

What to consider before purchase

Recommendations

Use appropriate fiber cleaning and testing equipment after installation. Perform an insertion loss check and visual inspection of endfaces. Avoid repeated bending near connectors and secure the cable to prevent mechanical strain; if routed through ceilings or trunking, maintain a bend radius consistent with manufacturer guidance even for G.657.A2 fiber.
