This is a LC (male) to LC (male) yellow OS2 simplex riser-rated patch straight cable that is used for high speed data transfer. OS2 is a standard single-mode optical fiber commonly used with wavelengths of 131nm and 155nm (9/125 microns), and has a maximum attenuation of 1dB/km. The OS2 standard is defined in ISO/IEC 1181. This riser (OFNR) cable is best suited for use in interior fiber-optic applications. A duplex cable is a two-strand fiber optic patch cable that works best with transceivers that both transmit and receive. Our patch cables are 1% compliant for all of your networking needs and are guaranteed by federal law to not affect or void OEM warranties. https://elecena.pl/product/30654419/addon-networks-add-lc-lc-5ms9smflz-5m-lc-male-to-lc-male-straight-yellow-os2 2026-09-03 https://elecena.pl/product/30654419/addon-networks-add-lc-lc-5ms9smflz-5m-lc-male-to-lc-male-straight-yellow-os2 2026-09-27
