- Anritsu has released the AH15203A/B series of broadband linear amplifiers—amplification modules featuring an integrated bias tee.
- These modules are designed for signal conditioning and characterization within next-generation optical transmission devices.
The AH15203A/B series amplifiers cover a frequency range from 200 kHz to 125 GHz (at -6 dB). They are capable of amplifying PAM4 signals at rates up to 140 Gbaud, delivering a maximum output voltage of 2.0 Vpp.
The amplifier offers a gain of +15.0 dB and a maximum time jitter of 300 fs. This frequency response enables line loss compensation while preserving waveform integrity during optical component evaluation. The integrated bias tee allows for the direct injection of the DC voltage required for modulator operating points, eliminating the need for external components.

Applications and standards context
This amplification module is designed to interface between digital signal processors (DSPs) and optical modulators. It targets direct-modulation (EML, DML, VCSEL) and coherent optical transmission applications used in 800GbE and 1.6TbE networks.
The development of this component is part of the standards evolution driven by the IEEE, specifically the IEEE 802.3dj work (defining 200 Gbit/s-per-lane IM-DD links over distances of 10 km to 40 km) and IEEE 802.3ds (targeting short-reach optical links at 200 Gbit/s per wavelength).
