光纤 OM1 OM2 OM3 中的OM到底什么意思，是什么单词的简写 ？
& & OM（Optical Mode）是光模式的意思。是多模光纤表示光纤等级的标准。& & OM1、 OM2、 OM3分别多模光纤的3个等级，不同等级传输时的带宽和最大距离不同，具体看下表：

光纤水峰衰减光纤-OH离吸收光能量造光定波范围内衰减适合拿做光传输耦合器肯定陶瓷其硬度且耐磨保证单模光纤耦合精度至于金属半用于模模光纤纤芯孔径光耦合要求没单模严格所综合考虑制造工艺及本情况模耦合器更使用金属MPO用于并行光缆传输设备使用及QSFP封装接口传输产品使用MT-RJ特别适合光纤桌面应用传输系统少用种接口连接器

光模式Optical Mode缩写 其OM1指传统62.5/125μm模光纤OM2指传统50/125μm模光纤OM3指新型万兆位模光纤
遇到高人了，继续请教您。1,光纤的水峰衰减如何理解？2.耦合器是陶瓷的好还是金属的好？ 听说过，前者好，而且适用于单模光纤 后者 适用于多模的。有这回事么？3.除了FC ST SC
LC 这几种光纤接口外，MPO
MT-RJ 这两种接口都什么时候用，常用的网络设备上有这样的接口么？THANKS
兄弟，我也是碰巧这个问题知道一点，我也不是干这行的。你后面的追问，我实在是不知道了，真不好意思帮不上你
1,光纤的水峰衰减如何理解？
低水峰光纤使整个标准单模传输窗口 1260nm--1625nm的衰减最小化2.耦合器是陶瓷的好还是金属的好？ 听说过，前者好，而且适用于单模光纤 后者 适用于多模的。有这回事么？
耦合器常规用陶瓷的比较多，金属的工业控制是选用的多一些。3.除了FC ST SC
LC 这几种光纤接口外，MPO
MT-RJ 这两种接口都什么时候用，常用的网络设备上有这样的接口么？MPO 和MT-RJ接口
多数是用在数据中心等高密度布线环境要求下，所采用的预连接 接头。

出门在外也不愁精彩文章推荐问：万兆多模光缆OM1、OM2、OM3、OM4是什么意思？答：OM1指850nm或1300nm满注入带宽在200/500MHZ以上的50um或芯径多模光纤。（千兆传输距离只有275米）千兆传输距离-275- A1b-OM1-美国标准OM2指850nm或1300nm满注入带宽在500/500MHZ以上的50um或芯径多模光纤。（千兆传输距离550米）50/125-千兆传输-550 -A1a-OM2-欧洲标准OM3和OM4是850nm激光话的50um芯径多模光纤，在采用850nm，VCSEL的10Gb/s以太网中，OM3光纤传输距离可以达到300M，OM4可以达到550M（OM3-150，OM3-300，OM3-550，分别再米内达到万兆――中心传输部分也是50微米，为万兆光纤）单模光纤带宽基本可以认为是无限，没有万兆之分
