How is the cable model named? What is the chromatogram of fiber optic cable?

Do you know how the cable model is named? GM stands for mobile optical cable for communication, GJ stands for optical cable for communication room (office), GS stands for optical cable for communication equipment, and F stands for non-metallic reinforcing member. What is the chromatogram of fiber optic cable?

Name method of optical cable model (YD/T908-2000)

1. The cable type consists of five parts

I, II, III, IV, V

I, indicating the cable category

GY--Outdoor optical cable for communication

GJ--indoor optical cable

MG--coal cable for coal mine

II. Strengthening component types

(No model)--Metal reinforcement member

F--non-metallic reinforcing member

III. Structural features

D--fiber ribbon structure

(unsigned)-- loose layered structure

X--central tubular structure

G--skeletal structure

T--filled

Z--flame retardant structure

C8--8 font self-supporting structure

IV, sheath

Y--polyethylene sheath

W--Entrained steel wire-polyethylene bonding sheath

S--steel-polyethylene bonding sheath

A--aluminum-polyethylene bonding sheath

V--polyvinyl chloride sheath

V, outer sheath

53-crepe steel strip longitudinally armored polyethylene sheath

23-wrapped steel tape armored polyethylene sheath

33-fine wire wrapped armored polyethylene sheath

43-thick wire wrapped armored polyethylene sheath

333-double thin steel wire wrapped armored polyethylene sheath

2. Representation of optical cable specifications

The specifications of the optical cable are expressed in terms of the number of optical fibers included in the optical cable and the type of optical fiber.

Example: The cable specifications of four G.652 single-mode fibers are expressed as 4B1.1 or 4B1. If the same cable contains different types of optical fibers, connect them with '+' in the middle of the specifications.

If it contains 4 multimode 50/125 fibers, it is expressed as 4A1a or 4A1.
