Introduction to Common Optical Cables

Following the 8 types of optical cables introduced in the first episode, this article will introduce the 9th to 13th types, namely: GYFTY, GYFTA, GYFTZA, GYTA33, and GYTA53+33.

9. GYFTY

“External use, ointment filled, non-metallic reinforcement polyethylene outer sheath”

10. GYFTA

“External use, grease filled, non-metallic reinforcement aluminum-polyethylene outer sheath”

Application scenarios: overhead, pipeline

11. GYFTZA

“External use, grease filled, non-metallic reinforcement aluminum-flame retardant polyethylene outer sheath”

12. GYTA33

“Outdoor use, ointment filled, aluminum-polyethylene inner sheath thin round steel wire armor, polyethylene outer sheath”

Application scenarios: steep slopes and crossing rivers

13. GYTA53+33

“Outdoor use, grease filled, aluminum-polyethylene inner sheath steel-polyethylene inner sheath, thin round steel wire armor, polyethylene outer sheath”

Application scenarios: direct burial, underwater, steep slopes or crossing rivers
