Some time ago Reliance Jio has announced new Fiber to Home (FTH) broadband Internet service which offers up to 1 Gbps throughput. This is very fast technology, but installation of fiber cable at our homes is required. Also, Reliance uses data plans for this new service. Airtel on the other hand has decided to provide us simpler, but still very efficient and fast Internet access service called V-Fiber. Recently Airtel has announced to launch V-Fiber service in Mumbai.
The name of new broadband Internet access offer suggests that this is fiber Internet technology which will compete with the Jio GigaFiber. The V-Fiber service from Airtel is able to provide Internet connection with up to 100 Mbps speed. I know that it is 10 times less than in case of GigaFiber from Reliance. However, Airtel’s proposal does not require any new cable installation and it can use your already installed DSL line. The only thing which you have to do is upgrade your modem. This may be very good strategy, because Airtel can already use the current infrastructure and they do not have upgrade cable installation in the whole city. The plans start from Rs 899 and new customers can avail the unlimited offer for 3 months.
V-Fiber is combination of fiber and Vectorization technologies.
It means that the whole city backbone network is based on the fiber connection. However, the so-called last line is made from cooper. Airtel uses Vectorization technology in order to provide extremely high speed on DSL line. The VDSL2 solution is able to provide up to 100 Mbps at distance of 400 meters. However, in case of longer copper lines, this speed decreases to 40 Mbps at 1000 meters distance. This new technology is very popular in Europe, because it allows cancelling interferences between cooper cables. As the result, the theoretical capacity of DSL line is not increased, but the practical throughputs are closer to theoretical ones.
