ExcelitasTechnologies launches new avalanche photodiodes

Industry technology leader ExcelitasTechnologies has launched the C30733BQC-01 InGaAs avalanche photodiode. The unique combination of high gain and fast recovery times and low noise performance makes it an ideal solution for high-end telecom test equipment applications, optical communications and distributed fiber sensing systems, and eye-safe LiDAR/ laser ranging devices, especially for smart cities and smart factories.

Avalanche photodiode uses unique chip design, advanced performance and typical operating gain of up to 40, representing a new trend in high-speed applications requiring the best signal-to-noise ratio of 1000nm to 1700 nm. Equipped with FC/APC connectors, the C30733BQC-01 avalanche photodiode can be easily installed in all fibre-based systems as an optical time-domain reflectometer (OTDR) and distributed fiber optic sensor (DOFS) for distributed temperature sensing (DTS), distributed audio sensing (DAS) and strain measurement.

"We are pleased to extend our family of next-generation sensor technologies with the C30733BQC-01 InGaAs Avalanche Photodiode," Jens Krause, high-performance sensor applications engineer at Ethelida, said, "With very low noise and high gain performance, this new product enables accurate measurements over long distances in fiber optic networks or in free space. Perfect for design engineers, application engineers and product development managers developing test equipment in the 1300 nm to 1650 nm range."

The C30733BQC-01 avalanche photodiode has the following characteristics

● 30 μm small active region

● High responsiveness

● Low dark current and noise

● The pigtail design facilitates fiber coupling

● Meet RoHS standard
