Description
The APT313311 is a high-performance 1310nm InGaAs photodiode and a transimpedance amplifier packaged for high-speed data communication.

The device inside packaged with InGaAs PIN and TIA. The PIN transduces incident light into optical current with high efficiency. The TIA converts the current signal into a voltage signal with a very low input noise current contribution. The TIA also can decrease the light to voltage conversion factor when the average incident optical power is relatively high. The golden wire’s pull force is strictly tested to guarantee its fastness.

The APT313311’s TO-can is sealed under the condition of dew point and airproof control. So it can provide the best work environment.

The miniaturized size LC adaptor with sleeve barrel and 4-pin LC package provide industry standard connection. Laser welding craftwork flow guarantee the device’s stability. ATOP reliability criterion strictly control each step of the device craftwork in order to ensure high reliability and the best performance.

It is designed for 1.25 GB/s SFF/SFP transceiver module. It is also available with a connector receptacle or as a single mode fiber pigtail. The device is applicable for 1310nm/1550nm optical fiber communication systems for 1.25 GB/s, typically showing high sensitivity of -26dBm.
