Chinese fiber-optic cable names may look complex, but once you know the letter codes, the cable's function, structure, protection, and application become crystal clear. 🔠 1️⃣ Function & Purpose G → Optical Cable (General prefix for fiber cables) Every standard. Cable designation illuminated: How cables can be easily identified Whether for a new installation or when expanding cabling in industrial or private applications, clear cable labelling is essential in order to select the cable approved for the respective application and also to ensure effective. Standard test method used primarily in aerospace and spacecraft applications to evaluate how much an epoxy material outgasses in a vacuum environment to ensure they meet the total weight loss (TML) and condensable volatile material (CVCM) thresholds. Standard Test Conditions run at 125°C (257°F).

Ⅰ: Classification code and its meaning are: GY—room (field) optical cable for communication; GR—soft optical cable for communication; GJ - optical cable in communication room (office); GS - optical cable in communication equipment;. When we cannot clearly understand the meaning of these 'A-Z letters' of optical cables, we cannot accurately understand the actual use of optical cables, so we need to understand the meaning of each letter in the Chinese optical cable model. This is a highly technical professional issue.
