Top-illuminated, high speed avalanche photodiode chip with a dual pad layout and a large optical aperture. The APD is optimized for single-mode Gigabit Passive Optical Networks (GPON) and 10 Gb/s SONET/SDH telecom applications. A key feature of this innovative APD is low excess noise, enabling receiver sensitivities of -29 dBm for 10 Gb/s NRZ signals when used with an appropriate TIA.
- Enables a receiver sensitivity of –29 dBm with commercially available TIAs
- High gain-bandwidth product: 90 GHz
- Large optical aperture
- Low operating bias: 29 V
- Low temperature dependence: 25 mV/°C
- Low capacitance: 140 fF
