This document describes the features and characteristics of the InGaAs-APD/Preamp receiver, including operating temperature range, supply voltage, reverse voltage, reverse current, etc. The receiver has high sensitivity, differential electrical output, and is suitable for long haul SONET, SDH, and DWDM systems.
The FRM5W232BS (gull‑wing) and FRM5W232BS‑A (through‑hole) are InGaAs avalanche photodiode (APD) receiver modules designed for long‑haul SONET, SDH, and DWDM systems operating up to 2.7 Gb/s. The device includes a GaAs transimpedance preamplifier, an integral thermistor, and a differential electrical output.
Key specifications include a typical sensitivity of –34 dBm, an operating temperature range of –40 °C to +85 °C, and a supply voltage of 3.15 V–3.45 V. The manual also lists absolute maximum ratings, optical/electrical characteristics, pin descriptions for both package types, and safety handling instructions.
