摘要

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10Gbit/s

4个信道总传输速率为40Gbit/s。模块采用工作波长为850nm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-42dB

接收灵敏度优于-11dBm

总体性能指标满足IEEE 802.3ba标准的要求。

Abstract

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 10Gbit/s and the total quad data rate of 40Gbit/s.It uses an 850nm 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-42dB

the receiver sensitivity better than-11dBm and the overall performance indexes satisfy the requirements of IEEE 802.3ba standard.
