PLC splitter is generally used in PON network. If you use it in PON network, then it can meet your requirement, but if not, it cannot achieve the bi-directional transmission. Because if multiple transceivers in the same wavelength from fiber 4 transmit signals to the IN fiber transceiver, then this transceiver cannot distinguish the signals. And PON network adopts Time division multiplexing technology, so the transceiver can distinguish the signals from different transceivers. by M***k on 03/25/2018
