20090148165 | OPTICAL FILTERING APPARATUS AND OPTICAL COMMUNICATION SYSTEM - Provided is an optical filtering apparatus which is applied to a Time Division Multiplexing Passive Optical Network (TDM-PON) based on a wavelength division multiplexing (WDM) method. The optical filtering apparatus includes: an optical signal distributing unit dividing an optical signal received from an optical line terminal into at least one optical signal with uniform output intensity, and distributing the at least one optical signal into at least one optical network unit; and a multiplexing unit combining a plurality of optical signals having different wavelengths received from the at least one optical network unit using a wavelength division multiplexing (WDM) method, and outputting the combined optical signal to the optical line terminal. Therefore, by using the optical filtering apparatus, it is possible to connect a large number of subscribers to an Optical Line Terminal (OLT) on a network such as Fiber To The Home (FTTH), thereby increasing efficiency in costs. | 06-11-2009 |
20090161874 | Key Management Method for Security and Device for Controlling Security Channel In Epon - A key management method for encrypting a frame in an Ethernet passive optical network (EPON) is provided. In the method, secure parameters including secure keys and their association numbers which are used in the present or will be used in the next by each secure channel are managed by composing a key information table. Then, it determines whether an association number of a received encryption frame is valid or not with reference to the key information table if the encryption frame of which association number has been changed is received. A secure key changes if the association number is determined to be valid, and the secure key does not change if the association number is not valid. | 06-25-2009 |
20090232313 | Method and Device for Controlling Security Channel in Epon - A method and device for controlling security of a communication channel between an OLT and an ONU in a secure channel control system of EPON formed of the OLT and the ONU having a cryptographic module, a key management module and a transmitter/receiver for transmitting/receiving frames, the method comprising the steps of: a) distributing a key between the OLT and the ONU; b) transferring the distributed key to the encryption modules of the OLT and ONU; c) activating a corresponding encryption module using the distributed key at one of the OLT and the ONU which starts a security function activation; d) transmitting an encryption module information message including activation state information of the corresponding encryption module from the side (transmitting side) having the activated encryption module to an opponent side (receiving side); and e) activating an encryption module by checking activation state information of the encryption module at the receiving side. | 09-17-2009 |
20090317084 | PASSIVE OPTICAL NETWORK SYSTEM AND OPTICAL SIGNAL RECEIVING METHOD THEREOF - A passive optical network system includes: a plurality of optical signal splitter receiving optical signals from a plurality of optical network units (ONUs) to provide a plurality of upstream optical signals having different wavelengths; a hybrid optical filter multiplexing the plurality of upstream optical signals in a wavelength division multiplexing (WDM) scheme; and an optical line terminal (OLT) receiving the multiplexed upstream optical signals in a time division multiplexing (TDM) scheme. Therefore, the network system can be easily expanded when the number of subscribers increases, and the optical loss can be minimized. | 12-24-2009 |
20100014866 | Digital Automatic Gain Control Apparatus and Method in Burst Mode Optical Receiver - A transimpedance amplifier for a burst mode optical communication converts a burst current signal into differential output voltage signals. Using a multi-level digital AGC mechanism, the transimpedance amplifier is rapidly adapted to a burst signal whose amplitude varies in a wide range. By using an adaptive level detection method, a multi-level digital AGC can be implemented without using ADC. In addition, because the transimpedance amplifier uses a selective reset generation scheme that performs a reset operation for itself after a high power burst, a burst mode operation can be performed without external reset signals. Accordingly, the transimpedance amplifier can be integrated with an optical detector within a TO-can. Furthermore, the transimpedance amplifier can have the burst mode capability and the best sensitivity. | 01-21-2010 |
