单模光纤的带宽zui宽，多模渐变光纤次之，多模突变光纤的带宽zui窄；单模光纤适于大容量远距离通信，多模渐变光纤适于中等容量中等距离的通信，而多模突变光纤只适于小容量的短距离通信。
在实际光纤传输系统中，还应配置与光纤配套的光源发生器件和光检测器件。目前zui常见的光源发生器件是发光二极管（LED）和注入激光二极管（ILD）。光检测器件是在接收端能够将光信号转化成电信号的器件，目前使用的光检测器件有光电二极管（PIN）和雪崩光电二极管（APD），光电二极管的价格较便宜，然而雪崩光电二极管却具有较高的灵敏度。
与一般的导向性通信介质相比，光纤具有很多优点：
1）光纤支持很宽的带宽，其范围大约在 1014～1015 HZ之间，这个范围覆盖了红外线和可见光的频谱。
2）具有很快的传输速率，当前限制其所能实现的传输速率的因素来自信号生成技术。
3）光纤抗电磁*力强，由于光纤中传输的是不受外界电磁干扰的光束，而光束本身又不向外辐射，因此它适用于长距离的信息传输及安全性要求较高的场合。
4）光纤衰减较小，中继器的间距较大。采用光纤传输信号时，在较长距离内可以不设置信号放大设备，从而减少了整个系统中继器的数目。
当然光纤也存在一些缺点，如系统成本较高、不易安装与维护、质地脆易断裂等。
1．并行通信与串行通信
数据通信主要有并行通信和串行通信两种方式。
并行通信是以字节或字为单位的数据传输方式，除了8根或16根数据线、一根公共线外，还需要数据通信联络用的控制线。并行通信的传送速度快，但是传输线的根数多，成本高，一般用于近距离的数据传送。并行通信一般用于PLC的内部，如PLC内部元件之间、PLC主机与扩展模块之间或近距离智能模块之间的数据通信。
串行通信是以二进制的位（bit）为单位的数据传输方式，每次只传送一位，除了地线外，在一个数据传输方向上只需要一根数据线，这根线既作为数据线又作为通信联络控制线，数据和联络信号在这根线上按位进行传送。串行通信需要的信号线少，zui少的只需要两三根线，适用于距离较远的场合。计算机和PLC都备有通用的串行通信接口，工业控制中一般使用串行通信。串行通信多用于PLC与计算机之间、多台PLC之间的数据通信。
