摘要： An optical network system can be used to update legacy passive optical networks by adding an optical transmitter, blocking filter, and/or pluggable or unpluggable optics. In one embodiment, an optical network system, including several optical transmitters and receivers, multiplexers, demultiplexers, erbium-doped fiber amplifier, and blocking filter, may be employed. The additional transmitter increases available bandwidth, while the blocking filter allows existing customers' service(s) to not be impacted. Another embodiment uses pluggable or unpluggable optics, instead of the aforementioned blocking filter, to receive and modulate optical signals to transmit services to end users. In one embodiment, an optical network system can be employed that allows for simultaneous upgrading of the system and providing of legacy services, while allowing for the of removal existing optical network components over time.

摘要： A method for transmitting a packet in a wireless access network based on a wavelength identification code scheme. The method comprises the steps of connecting n number of RNCs (Radio Network Controllers) to one sub-ring where the “n” is a positive integer, and assigning a unique wavelength to each RNC; identifying a packet to be transmitted between the RNCs located within a same sub-ring using the assigned unique wavelength, and transmitting the packet through an SRC (Sub-Ring Controller); connecting m number of SRCs to one main-ring where the “m” is a positive integer, and assigning a unique wavelength to each SRC; and detaching a wavelength identification code from the packet to be transmitted between the RNCs located within different sub-rings, and transmitting the packet having the encapsulated wavelength identification code through an MRC (Main-Ring Controller).
