DKT’s range of galvanic isolators eliminates problems from differences in the potential between the distribution network and the in-home network.
Galvanic isolators block balancing currents due to local potential differences, i.e. between the distribution network and the home network. These currents might flow both inside cables and on the cable screens, so the galvanic isolators acts as high-voltage (>2kV) capacitors both inside and outside.
The DKT galvanic isolators all fulfil the requirements in EN 60728-11 §11, i.e. they withstand a DC voltage of 2120 V for at least one minute.
Gi-1 (88006) is a one output port galvanic isolator. This can be placed between the distribution network and an existing home network.
DVU 1-4 GI (41140 + DVU 1-4GI 65 41141) has two output ports, and serves as a home network interface that splits the signal into a TV only branch without return path, and a DATA branch supporting either the DOCSIS 3.1 frequency bands, i.e. downstream 258-1218MHz and upstream 5-204MHz, or the DOCSIS 3.0 frequency bands (5-65MHz/87-1218MHz).
