Product overview
The Meskernel FO7890 PIN-FET receiver module combines a PIN photodiode with a low-noise, high-gain transimpedance amplifier for optical reception. Its applications include fiber optic gyroscope systems, fiber optic sensors and optical fiber communication systems, along with laser measurement, optical detection, and industrial and scientific optical sensing. Single-mode optical fiber couples light into the detector. Available spectral response ranges are 400–1100 nm and 1100–1650 nm, with transimpedance gain options extending from 12 kΩ to 1.2 MΩ.
The module uses a compact, hermetically sealed metal-DIP housing with an optical fiber pigtail and is available in 6-pin or 8-pin DIP packages. Version options include InGaAs, PIN/APD and Si APD, with customizable gain and bandwidth. Operation spans -45°C to +70°C. Nominal lead pitch is 2.54 mm, nominal lead length is 10.00 mm, and maximum fiber length is 1000.00 mm. The six-pin connection arrangement provides negative and positive power supplies, ground/case, an output and a no-connection pin.
