OSI introduces 1550nm InGaAs avalanche photodiode

New module targets light level detection and signal transmission applications

OSI Laser Diode has introduced the LAPD 3050, an InGaAs avalanche photodiode (APD) module that is designed for light level detection and/or signal transmission applications.

The high speed 2.5GHz device has a 50 µm active area. It features low dark current, low back reflection, and comes in a miniature package. With spectral response from 1000 nm to 1650 nm at 25 degC, the typical operational wavelength is 1550 nm.

The APD is housed in a hermetically sealed 3-pin coaxial package and coupled to a single-mode fibre pigtail. The overload-tolerant LAPD 3050 device is ideal for use in optical time-domain reflectometers (OTDRs), line receivers, and long haul applications. The breakdown voltage is from 50 V (min.) to 70 V (max.) and operating and storage temperatures range from -40 to 85degC.
