【摘要】：提出了一種基于小波包變換正交碼的多電平正交編碼的無(wú)源光網(wǎng)絡(luò)(PON)中上行信號(hào)復(fù)用和傳輸新方法,將PON系統(tǒng)中各個(gè)不同的光網(wǎng)絡(luò)單元(ONU)用戶用小波變換正交碼來(lái)進(jìn)行調(diào)制、復(fù)用和傳輸,能夠?qū)崿F(xiàn)各個(gè)不同ONU用戶共享一個(gè)波長(zhǎng)。由于采用了小波變換編碼,可以實(shí)現(xiàn)數(shù)量很多ONU用戶同時(shí)上行,在ONU端不需要突發(fā)光模塊以及多波長(zhǎng)激光器,因而成本低,傳輸速率高,接入數(shù)量多。給出了基于該方法的上行系統(tǒng)調(diào)制、復(fù)用和傳輸?shù)慕Y(jié)構(gòu)模型,并仿真了傳輸速率為1.25Gb/s和10Gb/s下不同路ONU用戶上行傳輸,仿真結(jié)果表明,最大可以實(shí)現(xiàn)上行32路,每路10Gb/s,總傳輸速率達(dá)到320Gb/s的高速PON系統(tǒng)。
[Abstract]:In this paper, a new method of uplink signal multiplexing and transmission in PON based on wavelet packet transform orthogonal code is proposed. Different optical network units in PON system are modulated by wavelet transform orthogonal code. Multiplexing and transmission, can achieve different ONU users share a wavelength. Because of the wavelet transform coding, many ONU users can be uplink at the same time, and the burst optical module and multi-wavelength laser are not needed in the ONU, so the cost is low, the transmission rate is high, and the number of access is large. The structural model of modulation, multiplexing and transmission in uplink system based on this method is given. The uplink transmission of different ONU users at the transmission rate of 1.25 GB / s and 10 GB / s is simulated. The simulation results show that the uplink 32 channels can be realized at the maximum. A high speed PON system with a total transmission rate of 320 GB / s per channel of 10 GB / s.
