Premlink is a WDM passive node factory in China that works on manufacturing all kinds of passive node with long years. PL190A-5S WDM passive node has a simple structure that made it very reliable and can be installed to STB or TV set directly.  PL190A-3S WDM passive node has two optical connectors. One is connecting to the incmoing fiber for mixed signals, the other one is connecting to XGSGPON & GPON ONU /ONT for Internet / data service.
To be a WDM passive node factory, Premlink designed this mode into a power-free style that does have power consumption, PL190A-5S is cost-effective passive optical receiver.
