Main Features:

1. Materials and Structure

High-purity glass: The core is usually doped with silicon to increase the refractive index, and the cladding is pure silicon or fluorine-doped glass. Double-layer structure: The core and cladding are made of single-mode fiber with a diameter of about 8-10μm

2. Ultra-low loss

Extremely low attenuation: It can be as low as 0.15~0.2dB/km in the 1550nm range, which is far superior to that of plastic optical fiber and copper cable.

Low dispersion: Single-mode optical fiber can achieve zero dispersion near 1310nm wavelength, which is suitable for high-speed long-distance transmission.

3. High bandwidth and high speed

Single-mode optical fiber: Supports Tbps-level transmission, used in backbone networks and submarine optical cables.

Multimode optical fiber: high-speed and short-distance transmission.

4. Excellent anti-interference

Complete dielectric characteristics: completely immune to electromagnetic interference,

lightning and radio frequency interference.

No radiation: no signal leakage, and high privacy.

5. Mechanical properties

High strength: protected by a coating layer, the tensile strength can reach 100 kpsi.

Flexible and bendable: the minimum bending radius can reach 5 mm, but it is necessary to avoid micro-bending loss.

6. Long service life and reliability

Slow aging: the service life exceeds 25 years without physical damage.

High stability: the light attenuation characteristics change very little over time, and frequent

maintenance is not required.

Application scenarios:

1. Communication network: long-distance trunk line, metropolitan area network, FTTH.

2. Special fields: Sensors: fiber optic gyroscope, temperature/voltage monitoring.

Medical: endoscope, laser surgical light guide.

Industrial: signal transmission in high temperature and strong electromagnetic environment.
