Description
It is a high-speed data transmission medium that uses light to carry signals through strands of glass or plastic fibers. It is designed for long-distance, high-performance communication and is widely used in telecommunications, internet connections and industrial applications.
Specifications
- Core material: glass or plastic
- Cladding : Surrounds the core and has a lower refractive index to reflect light back into the core.
- Buffer coating: Protects the fiber from moisture and physical damage.
- Types of fiber:
- Single-Mode fiber: small core; supports long-distance, high-bandwidth transmissions
- Multi-mode fiber: large core; supports shorter distances due to model dispersion.
- Wavelengths used:
- 850nm(for short-distances MMF)
- 1310nm & 1550nm( for long-distance SMF)
- Attenuation(signal loss): Measured in dB/km; lower values indicate better performance.
- Bandwidth; higher in smf
- Connector types: SC,LC, ST, MPO, etc.
- jacket types: indoor (tight-buffered),outdoor (loose-tube, armored for protection)
