Albis Optoelectronics’ PQW Amp series are high-speed microwave photoreceiver modules designed for direct optical-to-electrical conversion of RF-modulated optical signals. The module contains a high performance Albis photodiode and a linear, medium gain broadband amplifier. The optical input is supplied through a single- or multimode fiber pigtail. Model PQW20G1 provides a minimum bandwidth of 20 GHz. The photodiode inside long-wavelength model PQW20G1-L is designed to operate in the wavelength region from 1260 to 1620 nm. Short-wavelength model PQW20G1-S comes with a multimode fiber. The GaAs photodiode used inside this device is optimized for wavelengths ranging from 800 to 860 nm.
