Ekivalan OS2 Duplex kuitu-patchkaapeli ST/ST, 9/125 µm, LSZH, keltainen, 5 m COZ008STST2SJ0050A

For network technicians patching single-mode fibre links in data centres or campus backbones, this yellow 5-metre OS2 duplex patch cable connects ST-terminated ports with reliable low-loss performance. The 9/125 µm core/cladding supports long-haul transmission at 1310 nm and 1550 nm, while the LSZH jacket keeps emissions low in enclosed spaces.

Key specifications
