摘要
对速率10Gb/s传输距离可达10km的高速同轴连接型光发射组件(TOSA,又称高速同轴激光器)进行了研究。通过对该器件的光学结构和电高频性能等核心部分的深入分析和优化设计,成功研制出了可直接应用于小型化10Gb/sXFP光收发合一模块的TOSA。测试结果表明,在10.709Gb/s的调制速率下,消光比大于7dB,光眼图裕量大于15%,其整体性能达到了国外同类产品的先进水平。
The high speed coaxial laser diode assembly with data rate up to 10 Gb/s and transmitting distance up to 10 km is studied.Based on the in-depth analysis of the key characteristic inside the assembly covering from optical structure to high frequency electrical performance,and after a series of optimized design,the transmitter optical sub-assembly（TOSA）has been developed successfully,which can be directly adopted by 10 Gb/s small factor XFP transceiver.The final test shows that better than 7 dB extinction ratio and margin of more than 15% at 10.709 Gb/s are obtained,which keeps well compatible with the one of those advanced level products over the world.
