10Gbit/s EPON对称OLT光模块的设计

Design of symmetric OLT optical modules in 10 Gbit/s EPON systems

介绍了10Gbit/s EPON(以太网无源光网络)系统中对称OLT(光线路终端)光模块的设计方案和关键技术,重点描述在接收端如何实现双速率突发接收,以及10Gbit/s突发接收部分硬件电路的构成。测试结果表明:该模块在突发接收条件下接收端的接收建立时间和灵敏度均满足10Gbit/s EPON标准IEEE Std.802.3av的要求。

This paper introduces the design scheme and key technologies for Optical Line Terminal （OLT） modules in 10 Gbit/s Ethernet Passive Optical Network （EPON） systems and focuses on describing the implementation of dual-rate burst reception at the receiving end and the composition of the hardware circuits of 10 Gbit/s burst receiving part. The test results indicate that both the reception setup time and sensitivity of this module in burst reception condition satisfy the requirements of IEEE Std. 802.3av for 10 Gbit/s EPON.
