Extralink SC/APC–SC/APC jednovidový patch kábel G.657A 3 mm, 2 m

Extralink SC/APC–SC/APC singlemode patchcord G.657A 3 mm, 2 m is a simplex optical connection cable designed for singlemode networks and FTTH applications. It features SC/APC connectors on both ends and G.657.A1 bend-insensitive fiber that facilitates tight routing in subscriber premises and dense patching panels. The 3 mm jacket balances flexibility and mechanical protection while the 2 m length is intended for short interconnections between optical equipment, patch panels, splicing cabinets and terminal devices.

Advantages

The patchcord uses G.657.A1 singlemode fiber that offers improved bend performance compared with standard singlemode fibers, reducing signal loss in tight routing scenarios. SC/APC connectors provide reliable, low-reflection angled physical contact suitable for applications where return loss and signal integrity are critical. A 3 mm outer diameter provides a robust but flexible jacket that resists kinking and is easy to route in cable management systems. The simplex configuration ensures a simple, single-channel optical link for direct equipment-to-equipment or equipment-to-subscriber connections.

How to use

Inspect connectors before installation to ensure endfaces are clean and free of dust or debris. Align the SC/APC connector with the equipment adapter and push until it clicks into place; avoid excessive force. For removal, depress the latch and pull straight out. Route the cable following existing cable management paths, keeping bend radii larger than the specified minimum for G.657.A1 fiber to maintain optical performance. Do not subject the patchcord to sharp bends, crushing, or tensile loads beyond normal handling.

Recommendations

Use a fiber inspection microscope or cleaning tools before mating connectors to minimize insertion loss and return loss. For permanent installations, secure the patchcord in a management panel to prevent repeated stress on the connector. Store spare patchcords coiled with gentle loops and avoid tight wraps to preserve bend-insensitive fiber performance.
