Product Features

Ultra-low attenuation coefficient at 1550nm.

Extremely low sensitivity to hydrogen.

Lower polarization mode dispersion (PMD) coefficient: link design value of 0.04ps/√km.

Low attenuation in the 1460nm window: <0.25dB/km.

Adopts advanced preform manufacturing process.

Performance Advantages

Supports larger spans in practical applications, reducing the number of optical amplifiers, extending the distance between regenerators, accommodating faster transmission rates, and allowing flexible configuration of various network components, effectively reducing network construction costs.

Ensures low attenuation in the 1383nm wavelength region even after hydrogen aging, enhancing fiber performance and lifespan.

Extends the polarization mode dispersion-limited distance, lowering the cost of regeneration relays.

Enables the use of low-cost lasers and filters over a wider bandwidth.

Increases the pumping efficiency of C-band Raman amplifiers.

Higher purity, better geometric characteristics, and improved consistency.
