The performance of a cost-effective optical comb source using commercial off the shelf (COTS) components in a WDM passive optical network is demonstrated. Eight comb modes are individually modulated at 10.7 Gb/s and transmitted over 50 km of single mode fiber for downlink transmission. Error free performance is obtained for each comb line and a maximum performance difference of 1.4 dB is experienced between the eight channels. Colorless operation of the optical network unit is achieved by utilizing an integrated module consisting of a tunable laser and an electro-absorption modulator as an uplink transmitter. Finally the predicted downstream performance of the system, when all the channels are transmitted simultaneously, is numerically simulated.
展示了一种在波分复用无源光网络中使用商用现货（COTS）组件的具有成本效益的光梳状光源的性能。八个梳状模式分别以10.7 Gb/s进行调制，并通过50公里的单模光纤进行下行链路传输。每个梳状线都获得了无差错性能，并且八个通道之间的最大性能差异为1.4 dB。通过利用由可调谐激光器和电吸收调制器组成的集成模块作为上行链路发射器，实现了光网络单元的无色操作。最后，对系统在所有通道同时传输时的预测下行性能进行了数值模拟。
