Hamamatsu Photonics has introduced a new InGaAs APD (avalanche photodiode) detector which complements its range of high-speed optical receivers for data communication applications.
The new G10204-54 consists of an InGaAs APD connected to a high-speed pre-amplifier, giving an output voltage signal at data rates of up to 10,7 Gbps. To aid easy integration by the system vendor, the device is mounted in a metal optical sub-assembly ROSA package, which is compatible with the XMD industry standard. The G10204-54 has isolated housing and signal ground, with external connection being made with flex board interface.
Compared to the company's current range of 10 Gb ROSA devices such as the G9911, the new G10204 incorporates an APD receiver. This provides on-chip signal gain and higher sensitivity (-27 dBm with M = 7 at 10,7 Gbps), enabling data transmission over a much longer distance compared to existing devices.
