以太网无源光网络(EPON)已成为应用最广的宽带接入技术之一, 为其配备强大的网管系统是十分必要的。文章设计了EPON网管资源管理子系统, 以实现对网络资源的管理和状态的实时监控。首先介绍了EPON网管系统的总体架构, 随后重点阐述了资源管理子系统的设计方案, 最后分别在网管客户端、服务器端和代理侧予以实现。

In the last two decades we have studied and developed two types of laser speckle flowgraphy (LSFG) systems to visualize blood flow distribution in skin tissue, human retina, etc.. The system based on analyses of the laser scattering phenomena consists of
The main aim of this paper is to investigate the corneal damage effects induced by mid-infrared optical parametric oscillator (OPO) radiation. Experiments were performed to determine the corneal damage thresholds of New Zealand white rabbit at the wavelen
An efficient intracavity single-resonant optical parametric oscillator (OPO) at 1.571-micron eye-safe range using a non-critically phase-matched KTP crystal is reported. The OPO is excited by a diode side-pumped electro-optic Q-switched Nd:YAG laser at 1.
