Single Mode FTTH 4FO Fiber Optic Cable is a specialized optical cable designed for deployment in FTTH (Fiber to the Home) networks, featuring high-speed signal transmission over long distances.
Structure and Characteristics
- Cable Type: Single Mode (SM), utilizing a small optical core to transmit a single light beam, allowing signals to travel very long distances with minimal attenuation.
- Fiber Count: 4FO (4 Fiber Optic), meaning the cable contains 4 optical fibers inside, sufficient to provide service for a specific number of subscribers in an area.
- FTTH Structure: Specially designed for indoor or short-distance outdoor installation environments, typically featuring a figure-8 or flat structure for easy installation and splicing.
- Materials:
- Optical Core: Pure Silica Glass.
- Protective Jacket: Typically LSZH (Low Smoke Zero Halogen) or PE (Polyethylene) plastic, fire-retardant and environmentally friendly.
- Strength Member: Uses aramid yarn or steel wire to protect the optical fibers from tension and bending.
- Operating Wavelength: Typically 1310nm and 1550nm, standard wavelengths for Single Mode transmission.
Highlights
- High Speed and Bandwidth: Single Mode cables allow data transmission at extremely high speeds (Gigabits per second) and unlimited bandwidth, meeting the demands of Internet, 4K/8K TV, and high-demand services.
- Long Distance and Stable Transmission: Low signal attenuation enables long-distance transmission (several kilometers) while maintaining stable quality.
- Durability and Safety: The jacket is usually made of fire-resistant, low-smoke materials (LSZH) or UV-resistant PE, ensuring safety and high longevity when installed outdoors.
- Installation Flexibility: Compact, lightweight, and flexible design, easily bendable and routed through hidden corners in homes and residential areas.
Applications
- FTTH Networks (Fiber to the Home): Core application for pulling cables from distribution boxes (FAT/FTB) to private homes, apartments, and offices.
- Local Area Networks and Optical LAN: Used to connect network equipment in large buildings and factories requiring higher speeds and longer distances than copper cables.
- Surveillance Camera Systems: Used as a high-speed and stable signal transmission line for security camera systems, especially cameras placed at long distances.
Usage Notes
- Bending Radius: Absolutely do not bend the cable too sharply (minimum bending radius must typically be greater than 10 times the cable diameter). Sharp bending will break the inner optical fibers, causing severe signal attenuation.
- Tensile Strength: When pulling the cable, adhere to the manufacturer's maximum allowable pulling force. Excessive force can break or degrade the optical fibers.
- Connector Cleaning: Fiber ends (after connector termination or fusion splicing) must be cleaned with a specialized solution before connection to prevent dust from reducing signal quality.
- Storage: The cable should be stored in a dry place, away from direct sunlight or excessively high temperatures.
Single Mode FTTH 4FO Fiber Optic Cable is an advanced transmission solution, indispensable in building modern telecommunications network infrastructure. With high-speed data transmission capabilities, long distances, and high durability, it is the optimal choice for providing quality Internet and television services to end users.
