Today, a variety of industries including the medical, military, telecommunications, industrial, data storage, networking, and broadcast industries are able to apply and use fibre optic technology in a variety of applications. And, it is indeed relevant to say that telecommunications industry is the dominant user of optical fibre technology because the demand is high. In India, this demand has been on the rise and is being driven by factors like growth of fixed broadband, replacement of BSNL's ageing copper network by fibre optic cables (FOC), building an alternate network for Defence, wireless backhaul network up gradation and the need for higher speeds by 3G & broadband wireless access networks. India has an established backbone network connecting states with each other and centre. While FOC network exists till the block level, backhaul network is yet to be brought to Optical Fibre Cable Network. Almost 80-90% tower backhaul connections are still on microwave links and they do not offer support for higher bandwidth capacities. The beauty of fiber is that it has nearly unlimited bandwidth potential. Besides with increase in rural penetration, scarcity of spectrum is likely to increase further and consequently the demand of FOC for backhaul as well as BTS access will be on the rise.
