Ekivalan OS2 duplex patch kábel LC APC na LC UPC, 9/125 µm, žltý, 20 m COZ008LALC2SJ0200A

Fibre optic links often fail because of poor connector alignment or excessive insertion loss. This 20-metre OS2 single-mode duplex patch cable solves that by pairing a low-loss LC APC connector on one end with an LC UPC connector on the other, both factory-terminated and tested for reliable 1310 nm and 1550 nm transmission.

Who is it for

Network engineers and installers who need a dependable, bend-tolerant patch lead for FTTH, data centre interconnects, or long-haul backbone links. The yellow LSZH jacket makes it easy to identify as single-mode while meeting low-smoke and halogen-free requirements in public buildings.

Tips

For best performance, avoid pulling the cable by the connectors and respect the minimum bend radius, especially when routing around corners or through cable management. The APC connector is ideal for analogue RF and high-power applications, while the UPC end suits most digital links.
