This is a 7.0m (23ft) LC (male) to SC (male) yellow OS2 duplex plenum-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. Plenum-rated cables must self-extinguish and prevent re-ignition. Duplex cabling provides two-strands of fiber and is most commonly used in applications that utilize one lane to transmit and one lane to receive.
