Pin Number Pin Name Pin Function Description 1 Anode Anode of the LED , this is the positive terminal of the LED component within the module . The current flows from here to the cathode (Pin 2). 2 Cathode Cathode of the LED, this is the negative terminal of the LED. Current flows from this pin to the anode (Pin 1). 3 Vcc Power supply pin for the device. A positive voltage (typically +5V) is supplied here to power the LED. 4 GND Ground pin. It serves as the reference point for the electrical system and completes the circuit.Detailed Pin Function Description:
The HFBR-2521Z is a light-emitting diode (LED) transmitter used in fiber optic communication systems. It transmits digital data in the form of modulated light signals through fiber optic cables.
Pin 1 (Anode): The anode is the positive terminal where current enters the LED, enabling it to emit light when activated. Typically, a voltage around 5V is applied here, driving the LED in forward bias.
Pin 2 (Cathode): The cathode is the negative terminal of the LED. When the current flows from the anode to the cathode, the LED emits light. The voltage here should be lower than the anode voltage, and the device should always be connected in reverse bias to the anode.
Pin 3 (Vcc): This pin is used to supply power to the LED. It is connected to the power source (+5V in most cases). This ensures that the LED has enough voltage to operate correctly and emit light.
Pin 4 (GND): The ground pin is used to complete the electrical circuit, providing a reference point for the voltage. It connects to the system's ground.
