Product Features

Low attenuation coefficient at the 1383nm water peak.

Extremely low sensitivity to hydrogen.

Lower polarization mode dispersion (PMD) coefficient: link design value of 0.06ps/√km.

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

Performance Advantages

Improved fiber capacity, supporting all wavelengths from 1260nm to 1625nm, reducing costs by using affordable lasers, multiplexing filters, and more wavelength channels.

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

Extends the polarization mode dispersion-limited distance, reducing 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.
