This fibre-based signal distribution network is as simple as it is ingenious, and converts DSTV’s satellite signal into an optical signal, which is distributed to the individual subscriber’s decoder via the fibre network. This is done in one of two ways: Through a dedicated fibre line: When this is used both the Data and the DStv signal are transmitted via separate fibre cables. By using video overlay: The simpler of the two options, this means that the DSTV Data and the DStv signal both run on a single fibre optic line. The best part is that no matter which option is used, neither the internet connection speed, nor the data usage will be impacted negatively. Still dont understand ?
