This is a 69.0m (226.4ft) 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 1310nm and 1550nm (9/125 microns), and has a maximum attenuation of 1dB/km. The OS2 standard is defined in ISO/IEC 11801. This riser (OFNR) cable is best suited for use in interior fiber-optic applications. A simplex cable is a single strand of fiber that works best with bi-directional transceivers as well as other single-transmitting devices. Our patch cables are 100% compliant for all of your networking needs and are guaranteed by federal law to not affect or void OEM warranties.
