Signal distribution networks for optically switchable windows

A kit for installing a signal distribution network for providing signals to a plurality of optically switchable windows in a building, the kit comprising:

• a control panel comprising a signal supply and one or more ports connected to the signal supply;
• a primary insert line configured to be connected to the one or more ports of the control panel;
• a secondary insert line configured to be connected to the one or more ports of the control panel;
• a trunk line configured to be connected to the primary insert line at a first location of the trunk line and configured to be connected to the secondary insert line at a second location of the trunk line, the second location different from the first location, the trunk line comprising a plurality of conductors;
• a plurality of drop lines configured to be connected to the trunk line, each drop line configured to be connected to one or more of the optically switchable windows to provide signals from the trunk line to the one or more optically switchable windows;
• and
• a plurality of connectors configured to be connected between the plurality of drop lines and the trunk line, each connector of the plurality of connectors configured to provide an electrical path between the trunk line and a respective one of the plurality of drop lines.
