Full name of outdoor single-mode optical cable

Outdoor Single-Mode Optical Cable is formally known as OS2 Single-Mode Fiber Optic Cable.

Overview

OS2 fiber optic cable is the standard designation for outdoor single-mode optical cables, designed for long-distance, high-bandwidth transmission . Unlike OS1, which is tight-buffered and intended for indoor use, OS2 features a loose-tube design that protects the fiber from environmental factors such as temperature fluctuations, moisture, and ultraviolet light, making it suitable for aerial, duct, or direct-burial installations .

Key Characteristics

• Core Diameter: Typically 9 microns, supporting a single light mode for minimal signal dispersion .
• Attenuation: Lower signal loss than OS1, allowing transmission distances up to 200 km without amplification .
• Bandwidth: Supports high-speed networks, including 10GbE to 100GbE, and is compatible with DWDM systems .
• Standards Compliance: OS2 fibers generally conform to ITU-T G.652 specifications, particularly G.652.D, which ensures full-spectrum capability for modern telecom and data networks .

Applications

OS2 outdoor single-mode cables are widely used in:

• Telecommunication backbones
• Long-haul data networks
• Fiber-to-the-home (FTTH) deployments
• Inter-building or campus networks These cables are engineered to withstand harsh outdoor conditions while maintaining signal integrity over long distances, making them the preferred choice for outside plant (OSP) fiber installations . In summary, the full technical name for outdoor single-mode optical cable is OS2 Single-Mode Fiber Optic Cable, distinguished from indoor OS1 fiber by its design, durability, and long-distance performance.
