Special optical nodes

The Comtech special nodes are matched to networks with unregular topology. We have developed devices for EttH, elements with integrated WWDM filters and with separated ports for forward and return path. Also a sufficed demand was a switching mode power supply with supplementary battery to ensure the work of the monitoring transponder even in case of power-cut. Our main customers in this topic are Caiw, Magyar Telekom and UPC Hungary.
