User Manual

2.1 Appearance and Interface Description

The appearance of the module is shown in the figure below:

Figure 2-1 Appearance Diagram of the Detector Module (Left: FC Connector, Right: Free Space)

The upper interface is the optical input interface (FC/Free Space), the lower right is the power input interface (M8/or lead wire output), and the lower right is the signal output interface (SMA).

The output of the version with temperature compensation is at the GH1.25 terminal, which is defined as follows:

The interface definition is as follows:

Electrical Specifications

The APD module is a single power supply product: connect the red wire to 12V, the black wire to ground, with a current of 300mA. The current of the detector module during normal operation is less than 100mA.

1. Output Interface: SMA (Female);

2. Output Impedance: 50Ω;

3. Maximum Output Voltage:

   Products below 500MHz: ±3.6V (@High Z), ±1.8V (@50Ω);

   Products above 1GHz (inclusive): ±1V (@50Ω).

4. Spectral Response Range: 900nm - 1700nm;

5. Detector Responsivity: >0.95A/W @1550nm;

6. The optical input amplitude should not exceed the saturation power.

Performance Parameters

Performance Test Description:

1. Due to the different conditions of the FC connectors of the test light sources, the insertion loss of each detector varies, and the test results of the detector response will have slight differences;

2. The transimpedance gain of the detector is calculated under the condition that the output load is high impedance. If the output load is 50Ω, the gain is reduced to half of the nominal value;

3. The measurement results of detector noise and rise time are obtained under the following conditions:

    a: Oscilloscope input impedance 50Ω;

    b: Oscilloscope bandwidth is full bandwidth (≥1GHz);

    c: Oscilloscope time division is set to 100ns/div (Note: Noise varies significantly with different time divisions);

4. Test ambient temperature: 23℃±5℃;

5. Test relative humidity: 35%±15%;

6. Test operating voltage: ±12V;
