Single Mode Fiber (SMF) cables are engineered with an exceptionally small core diameter of 8-10 μm, enabling the transmission of light along a single pathway. This design minimizes signal reflections and dispersion, ensuring pristine signal integrity over extensive distances. SMF is the preferred choice for applications demanding long-distance, high-speed, and high-capacity data transmission.
Key Features
Core Size & Light Transmission
- Core Diameter: Ultra-small 8-10 μm core allows light to travel in a single mode, significantly reducing signal loss and modal dispersion.
- Light Transmission: Single-path light propagation ensures minimal interference and maximum signal clarity, ideal for high-quality data transmission.
Bandwidth
- Unlimited Capacity: Offers nearly limitless bandwidth, making it perfect for high-speed data transfers and future-proof network scalability.
Transmission Distance
- Long-Range Capability: Capable of transmitting signals over distances up to 100 kilometers or more without significant degradation, suitable for wide-area networks (WANs) and intercontinental communications.
Attenuation
-
- Low Signal Loss: Exhibits lower attenuation rates, ensuring reliable performance over long distances and maintaining signal strength.
Typical Applications
Telecommunications & Internet Backbones
- Extensively used in long-distance telecommunication lines and undersea cables, forming the backbone of global internet infrastructure for high-capacity data transmission.
Data Centers & Cloud Networks
- Essential for connecting geographically dispersed data centers, supporting high-speed links (10G, 40G, and beyond) with minimal signal loss for efficient large-scale data handling.
Wide Area Networks (WANs)
- Ideal for linking buildings within campuses, enterprise WANs, and city-wide networks, ensuring stable and high-performance communication over vast distances.
Broadcasting & Streaming
- Facilitates the transmission of high-definition video and live streaming data across long distances, perfect for large-scale events and broadcasting facilities.
