Innolume Showcases Its O-Band WDM SOA Portfolio for Next-Generation Optical Networks

Innolume offers a portfolio of wavelength-division multiplexing (WDM) semiconductor optical amplifiers (SOAs) optimized for key wavelength regions across the O-band.

The portfolio includes SOAs centered at 1260 nm, 1310 nm, and 1340 nm, allowing system designers to select wavelength-specific amplifier solutions for different transmission architectures. The 1260 nm SOA is intended for lower O-band WDM applications the 1310 nm SOA is optimized for LAN-WDM systems while the 1340 nm device extends the portfolio towards the upper O-band providing greater flexibility for wavelength planning in O-band optical networks. Together, they address a broad range of O-band communication architectures.

All three SOAs were evaluated in system-level transmission experiments using high-speed 100G PAM4-modulated optical signals. The measurements demonstrated effective amplification at the operating wavelength of each device and provide practical performance data for engineers developing high-speed optical links. By combining wavelength-specific amplifier designs with system-level transmission measurements, Innolume helps customers select the most appropriate SOA for their system architecture while simplifying component evaluation.

Innolume continues to expand its WDM SOA portfolio, supporting the development of next-generation optical communication systems with wavelength-specific optical amplification solutions.

Figure. Measured preFEC BER as a function of SOA input power for three Innolume O-band WDM semiconductor optical amplifiers using 100G PAM4 PRBS31 signals. Measurements were performed using wavelength-specific transceiver and channel configurations corresponding to the target application of each SOA. The results illustrate system-level performance and are not intended for direct comparison between devices.
