Kuitupatchkaapeli Extralink SC/UPC–SC/UPC simplex G.657.A2 40 m

Extralink Fiber Optic Patchcord SC/UPC to SC/UPC Simplex G.657.A2 40m is a single-mode patchcord designed for indoor optical connections and FTTH deployments. The cable uses bend-insensitive G.657.A2 fiber and SC/UPC connectors on both ends in a simplex configuration, providing a reliable low-loss link for connecting optical terminals, media converters, and distribution equipment. With a 40 meter length, this patchcord is suitable for linking equipment across technical rooms, apartments, or short-building spans where tight bend performance and consistent single-mode transmission are important.

Advantages

This patchcord combines G.657.A2 bend-insensitive fiber with SC/UPC terminations to reduce microbend and macrobend losses in constrained routing environments. The simplex design and standardized SC/UPC connectors ensure straightforward mating with common single-mode ports. The 40 m length allows flexible placement of devices without intermediate splices while maintaining stable insertion loss and return loss characteristics expected of single-mode jumpers.

Suitable for

When it may not be suitable

This single-mode simplex patchcord is not intended for multimode systems; using it in multimode links will cause significant loss and mismatch. It is also designed for indoor use and premises cabling; it lacks additional armoring or weatherproofing required for direct outdoor burial or prolonged exposure to harsh environmental conditions.

Key specifications

How to use

Route the patchcord following existing cable pathways, avoiding sharp kinks and maintaining recommended bend radii even though the fiber is bend-insensitive. Clean connector end faces with appropriate fiber cleaning wipes or tools before mating to ensure low insertion loss and reliable optical performance. Plug the SC/UPC connectors into the corresponding SC single-mode ports until the latch engages; avoid twisting or pulling on the connector body when making or releasing connections.

What to consider before purchase

Recommendations

For best results, keep connector end-faces clean, secure strain relief at patch panels or equipment, and avoid tight bends below the manufacturer recommended minimum radius. Use this SC/UPC simplex G.657.A2 40m patchcord for short to medium indoor runs where bend performance and single-mode transmission consistency are priorities.
