All about OFC SM fibre ( Single mode fibre)- It is a type of fibre optics cable that has smaller core diameter compared to multimode fibre. This means only a single mode of light can travel through it,resulting less signal loss and higher bandwidth. It transmits a single ray of light,which has higher bandwidth capabilities and preferred in longer distance applications. Multi mode Fibre Optic Cable- Large diameter core that allows multiple modes of light to propogate. As the core increases,more data passes through a given time. Quality of signal reduced over long distances. Typically used for short distances,data and audio/video applications in LANs. Windows of OFC - 1 st window - 850 nm - Short wavelength region 2 nd window - 1310 nm - Medium wavelength (O band) 3rd window - 1550 nm - Long Wavelength (C band) Attenuation is minimum at 3 rd window. 2nd and 3rd window are used in Single Mode Fibre. 1st and 2nd in Multi mode Fibre. Max speed of Cable laying in OFC - 15 meter/ min. L...
