It is a functional optical cable system that combines optical sensing technology with special optical cable structure. Its essential feature is that the optical fiber itself is used as a sensitive element to achieve real-time monitoring of physical quantities through modulation and demodulation of optical signals. Different from traditional communication optical cables, it realizes the functional integration of "transmission" and "sensing" and is the core carrier of the new generation of intelligent perception networks.

1. Size and structural characteristics
Core/cladding diameter:
Core diameter 1.0mm, cladding diameter 2.2mm, compared with quartz optical fiber (with larger geometric dimensions, convenient for naked eye observation and manual connection.
Structural composition:
Core: made of polymethyl methacrylate or fluorinated polymer, with a high refractive index;
Cladding: low refractive index polymer, forming total reflection conditions;
Sheath: The outer layer is mostly polyvinyl chloride or polyurethane, providing mechanical protection.
2. Optical transmission characteristics
Transmission wavelength:
Mainly works in the visible light band, the light source is mostly LED, the cost is lower than the laser light source required for quartz optical fiber.
Transmission loss:
The loss is high, much higher than quartz optical fiber, so the transmission distance is short, suitable for short-distance scenes.
Therefore, 1.0/2.2mm plastic optical fiber cable has "flexible and easy installation, low cost, and anti-interference" as its core advantages. Although its transmission performance is not as good as quartz optical fiber, it is irreplaceable in scenarios such as short-distance communication, industrial control, and consumer electronics. It is especially suitable for applications that are sensitive to construction convenience and cost.
