There are many types of fiber optic cables. Like other products, there are specific models and specifications. According to the provisions of "YD/T908-2000 Nomenclature of Optical Cable Models", the current optical cable model is composed of two parts, the form code of the optical cable and the specification of the optical fiber, separated by a short line in the middle.

The fiber optic cable model is composed of five parts: classification, strengthening member, derived shape (characteristic), sheath and outer sheath. The contents indicated by the codes of each part are as follows.

Optical cable classification code and its meaning

GY - outdoor optical cable for communication room (field);

GM - mobile optical cable for communication;

GJ - optical cable in communication room (office);

GS - optical cable in communication equipment;

GH - submarine optical cable for communication;

GT——Special optical cable for communication.

The code name of the reinforcement member and its meaning

No symbol—metal reinforcing member;

F—Non-metal reinforcing member.

The code names of derived features and their meanings

B—flat structure;

C—self-supporting structure;

D—fiber ribbon structure;

(No sign)——Dry water blocking structure

R - inflatable structure

(unsigned)—layer structure;

G - skeleton groove structure;

(unsigned) - fiber optic loose sleeve coating structure;

J——fiber tight sleeve coating structure;

E - ellipse shape;

T——Ointment filled structure;

X——Central bundle tube structure;

Z - flame retardant.
