Identify the difference between indoor optical fiber and outdoor optical fiber from different angles

What is the comparison between an indoor optical fiber and an outdoor optical fiber?
From model, purpose, and accessories
Indoor optical cable:
GJFJV: Mainly used for building or indoor laying or making fiber optic cable jumper.
Non-metallic reinforcing member, tight-fitting optical fiber, PVC sheath
Outdoor optical cable:
1. GYXTW: Laying of pipelines and overhead. Metal-reinforced member, center tube filling type, steel-polyethylene bonded sheath with steel wire
2. GYXTW53: Directly laid. Metal reinforced member, a center tube filled, steel-polyethylene bonded jacket with steel wire, longitudinally wrapped corrugated steel tape armored polyethylene sheath.
3. GYTA: Pipeline and overhead laying. Metal reinforced component, loose-skinned strand-filled type, aluminum-polyethylene bonded jacket.
4. GYTS: Pipeline and overhead laying. Metal reinforced member, loose-skinned strand-filled type, steel-polyethylene bonded sheath.
5. GYTY53: Directly laid. Metal reinforced member, loose-skinned strand-filled type, polyethylene sheath, longitudinally wrapped corrugated steel tape armor, polyethylene sleeve.
6. GYTA53: Laying directly. Metal reinforcing member, loose-skinned strand-filled type, aluminum-polyethylene bonded sheath, longitudinally wrapped corrugated steel tape armor, polyethylene sleeve.


7. GYTA33: Directly buried and laid underwater. Metal reinforced member, loose-skinned strand-filled type, aluminum-polyethylene bonded sheath, single thin round steel wire armor, polyethylene sleeve.
From the outer packaging and practical analysis:
1. Outdoor optical cable: The outer packaging is thick, and has some mechanical characteristics and environmental characteristics such as pressure resistance, corrosion resistance, and tensile resistance.
2. Indoor optical cable: mainly used indoors, the main features must be flexible, can be used in corners and other narrow places, followed by fire resistance, flame retardant, tensile, soft and other external characteristics.
Consider environmental factors:
1. Indoor optical cables generally do not have waterproof jackets
2 The outdoor optical cable must have a waterproof jacket.
Friendly reminder: There is no strict distinction between indoor optical cable and outdoor optical cable, that is, it can be used indoors or outdoor, according to the specific conditions of construction. The indoor optical cable is relatively soft and not tensile.
