Do you know the news optical cable The model is how to name? Mobile cable GM representative communication, GJ communication with the representative room (bureau) in cable, communication equipment GS cable, F represents the non metallic strength member. optical fiber and cable The chromatography is what?
Naming method of optical cable type (YD/T908-2000)
1, cable type consists of five parts.
I, II, III, IV and V
I, said cable categories
GY– communication outdoor optical cable
GJ– indoor fiber optic cable
MG– optical cable for coal mine
II, strengthen the component type
(no type) – metal reinforcing member
F– non metallic strength member
Third, structural characteristics
D– Optical fiber band structure
(unsigned) – loose tube stranded type structure
X– center tube structure
G– framing
T– filling type
Flame retardant Z– structure
C8–8 type self-supporting structure
IV, protective layer
Y– polyethylene sheath
W– with steel wire – polythene bonded sheath
S– steel – polythene bonded sheath
A– aluminum – polythene bonded sheath
V– PVC sheath
V, the outer protective layer
53- corrugated steel tape armoured PE sheathed longitudinal wrapping
23- around the Baotou Steel tape armoured PE sheath
33- thin steel wire wrapped armoured pesheath
43- thick steel wire wrapping armoured pesheath
333- double winding steel wire armoured and PE sheathed
The representation of 2, cable specifications
According to the number of fibers contained in the cable and category to express the specifications of optical fiber cable.
Example: 4 G.652 single-mode optical fiber cable specifications expressed as 4B1.1 or 4B1, if the different varieties of the same fiber cables contained in, in the middle size with a '' is.
If the optical fiber containing 4 multimode 50/125, said to 4A1a or 4A1.
Cable type composition code meaning
1, classification
