SIMBADE — New fiber amplifier in band O+E

Product description

Collaborative project (2022 – 2025)

The SIMBADE project aims to develop multi-band WDM optical transmission systems operating in the O-band (1260-1360 nm), E-band (1360-1460 nm) and S-band (1460-1530nm). This initiative aims to meet the growing demands for higher capacity and efficient communication systems, driving the future of fiber optic networks. Different optical fiber doped with rare-earth elements to amplify optical signals are investigated.

NEW DOPED FIBERS

IDIL is investigating various parameters related to the fibers, including their optical gain, absorption characteristics, and compatibility with existing telecom components. The study focuses on optimizing doping concentrations, fiber designs, pumping wavelengths and schemes to enhance amplification efficiency across the O+, E, and S bands. These advancements aim to enable next-generation multi-band WDM optical systems, improving data transmission capacity and energy efficiency in fiber optic networks.

NEW AMPLIFIER IN BAND O+E

Current erbium-doped optical amplifiers (EDFAs) are limited to the 1525-1625 nm wavelength range. In contrast, bismuth-doped optical fibers can operate beyond this range, particularly in the O-band (1260-1360 nm) and E-band (1360-1460 nm). This extended coverage is crucial for increasing bandwidth in existing telecom infrastructures.

IDIL, the gain block BDFA developer, is investigating various parameters related to the fibers and the optical assembly of the amplifier to boost amplification performance in the O-band and subsequently in the E-band. This is expected to result in a tenfold increase in bandwidth on existing networks. This fiber amplifier module will then be integrated and commercialized by Ekinops, with Orange Labs as the end user.
