Abstract:
1. A small form factor, pluggable optical network unit (ONU), comprising: a bi-directional optical transceiver configured to transmit optical signals to and receive optical signals from an optical line terminal (OLT); an ONU chip coupled to the optical transceiver and configured to communicate with the OLT, through the optical transceiver; a pluggable interface coupled to the ONU chip and configured to electrically interface between the ONU chip and a piece of subscriber premise equipment (SPE), whereby the pluggable interface can be directly plugged into the SPE; an inter-integrated circuit (I2C) bus which is coupled to the ONU chip and the pluggable interface; a serializer/deserializer (SERDES) module which is coupled between the pluggable interface and the ONU chip, thereby facilitating serial communication through the pluggable interface; a power management module configured to provide power to the ONU chip and the optical transceiver, using power delivered from the SPE through the pluggable interface; wherein the optical transceiver, the ONU chip, the power management module, and the serial interface are contained in a small form factor enclosure, thereby allowing the pluggable ONU to be directly plugged into the SPE and providing an Ethernet Passive Optical Network (EPON) uplink to the SPE without requiring an separate power supply.
