To face the increased demand for bandwidth, cost-effectiveness and simplicity of future Ethernet data communications, a comparison between two different solutions based on directly-modulated VCSEL sources and Silicon Photonics technologies is carried out. Also by exploiting 4-PAM modulation, the transmission of 50-Gb/s and beyond capacity per channel is analyzed by means of BER performance. Applications for optical backplane, very short reach and in case of client-optics networks and intra and inter massive data centers communications (up to 10 km) are taken into account. A comparative analysis based on the power consumption is also proposed.
为了应对未来以太网数据通信对带宽、成本效益和简单性不断增长的需求，对基于直接调制垂直腔面发射激光器（VCSEL）源和硅光子技术的两种不同解决方案进行了比较。同样通过利用4脉冲幅度调制（4-PAM），通过误码率（BER）性能分析了每通道50 Gb/s及以上容量的传输。考虑了光背板、极短距离以及客户端光网络和大规模数据中心内部及之间通信（长达10公里）的应用。还提出了基于功耗的比较分析。
