Design of optical fiber converter of Gigabit Ethernet based on FPGA 基于FPGA的千兆以太网光纤转换器的设计
By default the electric interface of general Fast Ethernet ( FE ) is in auto-negotiation mode, while the FE optical interface and the Gigabit Ethernet ( GE ) interface are in non-auto-negotiation mode. 缺省情况下,普通以太网FE电接口处于自动协商状态,FE光口为非自动协商状态,而GE接口处于非自动协商状态。
A CMOS preamplifier for optical access network systems and gigabit Ethernet systems is realized. 设计并实现了用于光纤用户网和千兆以太网光接收机的CMOS前置放大器。
Broadband Passive Optical Network System based on Gigabit Ethernet 基于千兆以太网的宽带无源光网络系统
By constructing an optical system with an active lightsource, the target catenary images are captured as clearly as possible using high-resolution line array camera with Gigabit Ethernet interface, which facilitates subsequent catenary wear measurement and calculation. 搭建了实验平台,在提供主动光源的条件下,利用高分辨率千兆以太网线阵摄像机对目标采集尽可能清晰的图像,为后续接触网磨耗的测量和计算提供便利。
