针对目前光通信对传输速率要求不断提高的问题,设计并实现了 QSFP+(4通道小型可热插拔)收发合一光模块,其单信道传输速率可达10 Gbit/s,4个信道总传输速率为40 Gbit/s。模块采用工作波长为850 nm的 VCSEL(垂直腔表面发射激光器)阵列作为光发射器件,高速PIN(光电二极管)型PD(光检测器)阵列作为光接收器件,与传统的设计相比,降低了设计复杂度和整体成本。对光模块进行了相关仿真和测试,结果表明,通道串扰低于-42 dB,接收灵敏度优于-11 dBm,总体性能指标满足 IEEE 802.3ba标准的要求。

In view of the current requirements for ceaselessly increasing the transmission rate of optical communications,this paper designs and realizes a Quad Small Form-factor Pluggable Plus (QSFP+)optical transceiver module,with single-channel transmission rate up to 10 Gbit/s and the total quad data rate of 40 Gbit/s.It uses an 850 nm Vertical-Cavity Surface-Emitting Laser (VCSEL)array as the light-emitting device and a high-speed PIN Photoelectric Detector (PD)array as a light receiving device.Compared with the traditional design,this model lowers the designing complexity and the overall cost.The simulation and test results show that the channel crosstalk is lower than -42 dB,the receiver sensitivity better than -1 1 dBm and the o-verall performance indexes satisfy the requirements of IEEE 802.3ba standard.
