How do Chinese (GY/GJ) and International naming conventions for fiber cables differ?

In the international market, fiber cables are typically categorized by their application (e.g., ADSS, OPGW, Micro-duct) and their fiber grade (e.g., OS2, OM4). The Chinese system uses the GB/T (Guobiao) code, which focuses on the installation environment and structural components using Pinyin initials.

Chinese System (GB/T): Common models include GYTS (Outdoor, loose tube, steel tape armor), GYTA (Outdoor, aluminum tape armor), GYXTW (Central tube, light-armored), and GJXH (Indoor drop cable).

International System (ISO/IEC & TIA): Focuses on construction types such as Duct Cable, Direct Buried, All-Dielectric Self-Supporting (ADSS), and Optical Ground Wire (OPGW). Performance is defined by fiber categories like G.652.D (Singlemode) or OM3/OM4 (Multimode).
