OS1 and OS2 are the specifications for single-mode optical fibre cable. 10km for 1000Base-T at 1310nm, and 80-100km at 1550nm. It details the fiber's geometrical, optical. In computer networking, Gigabit Ethernet (GbE or 1 GigE) is the transmission of Ethernet frames at a rate of a gigabit per second. The most popular variant, 1000BASE-T, is defined by the IEEE 802. It operates at a 1310nm wavelength and is widely used in enterprise, campus, and access networks where copper cabling or short-reach multimode optics are no. The single-mode fibres in telecommunication cables operate at 1310 or 1550 nm wavelength. 10km. OS1 single mode fiber optic cables are made with a single mode fiber core, which means that they have a very small core diameter of 9 microns. This allows the cables to transmit data over much longer distances than multimode fibers, with less signal loss and better quality.
