摘要： An optical communication network configuration method for creating a link between an optical network unit (ONU) and an optical line terminal (OLT) is provided. The configuration method comprises following steps. The ONU submits a universal management information base (universal MIB) to the OLT. The universal MIB is pre-stored in the ONU, and is compatible with various different OLT models. The ONU receives a set of configuration parameters from the OLT and recognizes the type of the OLT accordingly. The ONU selects a management information base (MIB) matching the OLT according to the recognized type of OLT. The ONU uses the MIB matching the OLT to create an ONU management and control interface (OMCI) with the OLT.

摘要： A communication device is provided. The communication device includes a circuit board, a connector and a RF noise shield. The connector is disposed on the circuit board for being connected with an external connector on a docking side of the connector. The RF noise shield is disposed on the circuit board and configured to cover and be separated from the connector by a spacing. The RF noise shield further has an opening arranged on the docking side. The opening is arranged on a side of the RF noise shield facing the external device, such that the RF noise shield forms an absorptive/reflective cavity. When the external device approaches or connects, not only the RF noise radiated from the connector of the external device but also the RF noise radiated from the connector of the device itself may be absorbed and/or reflected through the absorptive/reflective cavity.
