Fiber jackets are protective coverings used for fiber optic cables to safeguard them from physical damage, environmental factors, and interference. The main types of fiber jackets are categorized based on their material composition, durability, and intended use. Here are the different types:
1. PVC (Polyvinyl Chloride) Jacket
Description: PVC jackets are commonly used in indoor installations and provide basic protection for fiber optic cables.
Advantages: Cost-effective; Lightweight; Flame-retardant
Applications: Suitable for general indoor applications but not recommended for outdoor use due to limited resistance to UV light and harsh environments.
2. LSZH (Low Smoke Zero Halogen) Jacket
Description: LSZH jackets emit low smoke and no toxic halogen gases when exposed to fire, making them ideal for environments where safety is a priority.
Advantages: Smoke and toxicity reduction in case of fire; Suitable for confined spaces like data centers, tunnels, and public buildings
Applications: Used in environments requiring safety and minimal smoke production, such as airports, schools, and hospitals.
3. Polyethylene (PE) Jacket
Description: PE jackets offer more durability and environmental protection, making them suitable for outdoor installations.
Advantages: Water-resistant; UV-resistant; Suitable for outdoor environments
Applications: Common in outdoor fiber optic cables, especially for aerial and underground installations.
4. Teflon (PTFE) Jacket
Description: Teflon jackets are highly durable and resistant to high temperatures, chemicals, and physical wear.
Advantages: High resistance to heat and chemicals; Flame-resistant; Long lifespan
Applications: Ideal for harsh industrial environments and high-temperature conditions, such as in aerospace, military, or chemical processing industries.
5. Aramid Fiber (Kevlar) Jacket
Description: Aramid fiber, often branded as Kevlar, is used as a strength member in fiber optic cables to prevent breakage or damage under stress.
Advantages: Provides high tensile strength; Abrasion-resistant; Light and flexible
Applications: Commonly used in military, aerospace, and industrial applications where cables are exposed to extreme physical conditions.
6. E-glass or S-glass Jacket
Description: E-glass (electrical glass) or S-glass (structural glass) fibers are used in jackets to enhance mechanical strength and thermal performance.
Advantages: High strength-to-weight ratio; High temperature and chemical resistance
Applications: Used in specialized industrial and military applications where higher mechanical and thermal properties are required.
7. Plenum Jacket
Description: A plenum-rated jacket is made for fiber optic cables used in air ducts, plenums, or other spaces that facilitate air circulation. These jackets are fire-resistant and emit minimal smoke.
Advantages: Fire-resistant; Low smoke emission
Applications: Suitable for commercial buildings, office spaces, and other areas where cables are run through air ducts.
8. Riser Jacket
Description: Riser-rated jackets are designed for use in vertical spaces between floors in a building. These jackets provide a higher level of flame resistance than standard PVC jackets but are not intended for plenums.
Advantages: Flame-resistant; Suitable for vertical installation in buildings
Applications: Common in multi-floor buildings, such as in the riser spaces between floors for telecommunications and networking.
9. Armor Jacket
Description: Armor jackets are protective covers made of materials like steel or aluminum, providing mechanical protection against physical damage, such as rodent attacks or impact.
Advantages: Physical protection against cuts, abrasions, and impact; Enhanced durability
Applications: Used in areas with high risk of physical damage, such as outdoor installations, industrial settings, or areas with potential rodent interference.
Each of these jackets offers different levels of protection, flexibility, and resistance to environmental conditions, making them suitable for a wide range of fiber optic applications. The choice of jacket depends on the installation environment and specific requirements.
