Product Description:
This low water peak non-dispersion-shifted single-mode optical fiber meets or exceeds the optical fiber standards of ITU-T G.652D and IEC60793-2-50 B1.3. It is suitable for transmission systems across the full spectrum from 1260nm to 1625nm. It eliminates the absorption water peak near 1383nm caused by hydroxyl ions in conventional single-mode optical fibers, extending the operational window to the E-band (1380nm to 1480nm). Its attenuation and dispersion characteristics are optimized across the entire spectrum, meeting the requirements for multi-channel, high-speed transmission over a single optical fiber.
