Information About1000base-lx |
|
1000BASE-LX is specified to work over a distance of up to 2 km over 9 µm Single-mode Fiber . In practice it will often operate correctly over a much greater distance. Many manufacturers will guarantee operation up to 10 or 20 km provided that their equipment is used at both ends of the link. 1000BASE-LX will also run over Multi-mode Fiber with a maximum segment length of 550 m. For any link distance greater than 300 m, the use of a special Launch Conditioning Patchcord may be required. This launches the laser at a precise offset from the centre of the fiber which causes it to spread across the diameter of the fiber core. This reduces the effect known as Differential Mode Delay which occurs when the laser couples onto only a small number of available modes in multi-mode fiber. SEE ALSO |
