70 Vol. 42 No. 2 - May 2020 Issue There has always been a clear divide between upstream and downstream data splits, making it possible to upgrade signals in the existing network using by-pass filters and diplex filters in the active components. But this separation has become a limiting factor when upgrading the network; each upgrade requires new filters and additional labour. Technetix has now developed a bi-directional amplifier, without the need for diplex filters. This article will explain how to create more bandwidth and flexibility within the same infrastructure and how this technology will make 1.8GHz ESD installations feasible without amplifier respacing. by Jan Ariesen, Chief Technology Officer Unleashing technical Jan Ariesen’s career in the cable industry started in 1983 when he joined the Research &Development teamat Tratec in the Netherlands, where he developed numerous headend, access and In-home products. Tratec and Technetix joined forces in 2005 and Jan’s role became more involved with the technology and commercial teams. Jan became Chief Technical Officer (CTO) of Technetix in 2012 and, with his team, has created innovative technologies and products that improve network performance and make them ready for the future. He is now Chief Technology Officer at Technetix. Jan Ariesen, CTO, Technetix Imagine a world in which the telephone had been limited to push-to-talk functionality. The speed and pattern of global economic development might now look quite different, because limiting the rate at which data can be exchanged is a drag on progress. Yet similar restrictions across cable networks are generally accepted. The necessary splitting of frequencies for upstream and downstream traffic has imposed a heavy cost, putting a significant chunk of the frequency range beyond use. Today, some of your network's theoretical resources are left constantly dark in a ‘crossover area’, effectively dead. It cannot be accessed...until now. Technetix has developed and patented an amplifier solution which puts the entire frequency range into play. Not only does the amplifier allow all of the frequencies to be used all of the time, the frequency split becomes so flexible that it can adapt in real-time to the live balance of upstream and downstream traffic. Perhaps even more significantly, it opens cable to the world of full duplex networks. Endless Possibilities for Cable Networks
