1. A passive optical network (PON) system comprising:

  • an optical line termination (OLT) of a PON outside a building;

    an optical network terminal (ONT) of a PON inside the building; and

    a transceiver bridge disposed between the OLT and the ONT, the transceiver bridge comprising;

    at least one first transceiver outside the building communicatively coupled to the OLT and configured for wirelessly transmitting and receiving data from the PON;

    at least one second transceiver communicatively coupled to the ONT and configured to wirelessly transmit and receive data from the at least one first transceiver, wherein each of the at least one first transceiver and the at least one second transceiver comprises a radio frequency (RF) coding and decoding module, a first and a second RF mixer, a duplexer and a local oscillator;

    a first PON transceiver and a first physical (PHY) interface and a second PON transceiver and a second physical (PHY) interface, the first PHY interface being disposed between the first PON transceiver and the at least one first transceiver and the second PHY interface being disposed between the second PON transceiver and the at least one second transceiver; and

    a first limiting amplifier and laser diode driver disposed between the first PON transceiver and the first PHY interface and a second limiting amplifier and laser diode driver disposed between the second PON transceiver and the second PHY interface, each of the first limiting amplifier and laser diode driver and the second limiting amplifier and laser diode driver amplifying a first signal and a second signal from the first PON transceiver and the second PON transceiver, respectively, and modifying a third signal and a fourth signal from the first PHY interface and the second PHY interface, respectively, for application to the first PON transceiver and the second PON transceiver, respectively.
