Excelitas InGaAs APDs provide high quantum efficiency (QE), high responsivity and low noise in the spectral range between 1000 nm and 1700 nm.
The new C30645EH-137 features Excelitas’ cutting-edge low noise performance, together with a large dV > 4 V. dV defines the span of bias voltage from Gain 10 to Breakdown.
With a large dV, customers can more easily operate the diodes at high gains > 10 over a broad temperature range while simultaneously keeping the noise low.
With their high bandwidth and low noise, the Excelitas C30645 Series helps OEMs and system manufacturers achieve cutting-edge noise specifications with optimal Signal-to-Noise Ratios (SNRs).
In particular, the new and enhanced low-noise option helps increase range and performance on LiDAR and eye-safe range-finding systems with the same laser output power.
Coherent OTDR and fibre sensing applications like DTS or DAS benefit from enhanced sensitivity on longer ranges when detecting Raman-scattered signals.
