Possible refractive index profiles and other major parameters of the small dispersion single mode fiber (SDSMF) with ±2 ps/km/nm dispersion are presented in this paper, and their applications are discussed. Results show that SDSMF is suitable for high speed, WDM+EDFA systems, both for its non zero dispersion to effectively suppress the four wave mixing (FWM) effect, and small dispersion to avoid severe dispersion induced degradation.

Possible refractive index profiles and other major parameters of the small dispersion single mode fiber (SDSMF) with ±2 ps/km/nm dispersion are presented in this paper, and their applications are discussed. Results show that SDSMF is suitable for high speed, WDM+EDFA systems, both for its non zero dispersion to effectively suppress the four wave mixing (FWM) effect, and small dispersion to avoid severe dispersion induced degradation. When dispersion compensation is employed in the sequence of ITU T G.652 conventional single mode fiber (CSMF) and negative SDSMF between two adjacent in line amplifiers in a 10×10 Gb/s, 10 stage EDFA system, it offers the advantage of not only reducing the required system bandwidth from 16.2 nm to 9.4 nm at tolerable penalties caused by dispersion and FWM, but also making it possible for equal channel spacing transmission which significantly simplifies system design.

给出了色散系数分别为(±2ps/km/nm的小色散单模光纤一种可能的折射率分布及主要的设计参数,并讨论了此光纤在系统中的应用。结果表明小色散单模光纤具有的适当色散,既可有效抑制四波混频,又不致造成严重的色散限制,故适于高速、多路光纤通信系统采用。在系统中同时使用色散补偿技术时,在相邻在线放大器间采用ITU-TG.652常规单模光纤结合负小色散单模光纤的方案不仅可有效地抑制四波混频并减小光纤色散限制,使10×10Gb/s、10级掺铒光纤放大器系统占用带宽从16.2nm压缩到9.4nm;甚至可能实现等间距信道传输,从而大大简化了此类系统的设计

The method of equal channel angular pressing (ECAP) has been used to investigate the effects on structure of aluminum alloy 2024. The ECAP can be used to produce large plastic strain, which can refine the original grain and the thin needle phase dispersed in the structure. The initial texture structure can be cleared away as the equivalent true strain is high enough.

Symmetric push-pull cyclic deformation behavior of submicrometer grained copper pro-cessed by equal channel angular extrusion (ECAE) technique was investigated under constant plastic straincontrol at room temperature. Cyclic softening without any saturation until fracture occurs at εpl=5×10(-4)and1×10(-3), whereas no detective change of stress amplitude is found for εpl=1×10(-4) until 5000 cycles.Surface deformation feature observations using optical microscope and SEM-electron channeling contrast(SEM-ECC) technique show that there are 'slip lines' resembling the slip line of single crystal inappearance. The 'slip lines' are at about 45°with respect to the loading axis on the lateral surfaceand perpendicular to the loading axis on the front surface and can be divided into two kinds of thin andlong'slip line' as well as wide and short micro-shear-band according to their microscopic morpholo-gies. The formation of above mentioned two kinds of strain localization is discussed on the viewpoints ofcooperative grain boundary sliding and cooperative grain deformation, respectively.
