摘要 | Low cost implementation of broadband upstream transmission for local and access network applications is made possible through the use of modulated downstream signals in a wavelength division multiplexed (WDM) passive optical network (PON) to injection-lock vertical-cavity surface-emitting lasers (VCSELs) for operation as stable, uncooled, and directly-modulated upstream transmitters. By way of example and not limitation, an optical network unit comprises: downstream input, photoreceiver, tunable laser, upstream output, and means for directionally coupling the downstream input into the tunable laser for modulating the output wavelength which is coupled to the upstream output. |
其他摘要 | 通过在波分复用(WDM)无源光网络(PON)中使用调制下行信号到注入锁定垂直腔面发射激光器(VCSEL),可以实现本地和接入网应用的宽带上行传输的低成本实现。 )用于稳定,非冷却和直接调制的上游发射机。作为示例而非限制,光网络单元包括:下游输入,光接收器,可调谐激光器,上游输出,以及用于将下游输入定向耦合到可调谐激光器中以调制耦合到上游输出的输出波长的装置。 |
