Description:
The FPD3R2KX is a Germanium Avalanche Photodetector with a multi mode fiber pigtail for use in optical transmission systems operating at a high bit rate and over long distances. The 50um photosensitive diameter is optimized to achieve both higher coupling efficiency with a multi mode fiber and high electrical performance. The APD uses a planer chip structure with a guard ring to achieve low dark current and high reliability. A laser welding assembly process assures long term stability. The FPD3R2KX package contains a hermetically sealed APD with lens coupled to a graded index 50/125um diameter multi mode fiber.
Each device comes in with its own birth certificate as shown on the last picture.
