3 规格

Specifications

3.1 规格的构成Designation of specifications

光缆规格由光纤和导电芯线的有关规格组成。光纤的规格与导电芯线的规格之间用“+”号隔开。如图所示。

The specifications of the optical fiber cable consists of specifications of optical fiber and conductor, and both specifications are separated by a ?? as shown in figure.

3.2 光纤规格的构成Designation of optical fiber specifications

光纤的规格由光纤数和光纤类别组成，注：如果同根光缆中含有两种或两种以上规格（光纤数和类别）的光纤时，中间应用“+”号联接。光纤数的代号用光缆中同类别光纤的实际有效数目的数字表示。

The specification of optical fiber consists of number and classification of optical fiber. Note: If there are two and over specifications (number and classifications) of fiber in a same optical cable, they must be connected by a ?? Code of fiber count is indicated by an effective number of the same class of fiber in the optical fiber cable.
