Pin Function Specifications & Detailed Pin Description:
Since you requested a full explanation of the pins with a specific emphasis on every pin, here is the complete description for the HFBR-1414TZ optical transceiver module.
Pinout Configuration:Pin 1: Vcc ( Power Supply)
Function: Provides the main power supply for the module. Typically requires a voltage of 3.3V.
Pin 2: GND (Ground)
Function: Provides the ground reference for the module.
Pin 3: TD+ (Transmit Data +)
Function: The positive differential data input for transmission. It connects to the sending device to transmit data.
Pin 4: TD- (Transmit Data -)
Function: The negative differential data input for transmission. This pin pairs with TD+ for differential signaling.
Pin 5: RD+ (Receive Data +)
Function: The positive differential data output for reception. The received data is output as a differential signal on this pin.
Pin 6: RD- (Receive Data -)
Function: The negative differential data output for reception. It pairs with RD+ for differential signaling in reception.
Pin 7: VeeT (Transmit Ground)
Function: This is the ground for the transmitter section of the module, separate from the main ground.
Pin 8: VeeR (Receive Ground)
Function: This is the ground for the receiver section of the module, separate from the main ground.
Pin 9: TX Fault (Transmit Fault)
Function: This pin signals any faults during transmission. It will be pulled low (typically logic 0) in the event of a failure like an optical link fault.
Pin 10: RX_LOS (Receiver Loss of Signal)
Function: This pin indicates if the receiver is not receiving a valid signal. It will be pulled low (typically logic 0) when the signal is lost.
Pin 11: NC (No Connect)
Function: This pin is not connected to any internal circuitry and can be left unconnected in your design.
Pin 12: NC (No Connect)
Function: Same as Pin 11; no internal connections.

What is the operating voltage for the HFBR-1414TZ? The HFBR-1414TZ operates at 3.3V for its power supply (Pin 1 - Vcc). How do I connect the data signals for transmission and reception? For transmission, you connect the data signal to the TD+ (Pin 3) and TD- (Pin 4) pins, while for reception, connect the receiver data signals to the RD+ (Pin 5) and RD- (Pin 6) pins. What happens if there is a fault in the transmission? If there is a fault in the transmission, the TX Fault pin (Pin 9) will be pulled low to indicate a problem. What does the RX_LOS pin indicate? The RX_LOS pin (Pin 10) indicates if the receiver is not receiving a valid signal and will be pulled low when the signal is lost. Can I leave the NC pins unconnected? Yes, the NC pins (Pin 11 and Pin 12) are not connected internally and can be left unconnected. What is the significance of the VeeT and VeeR pins? VeeT (Pin 7) is the ground for the transmitter section, while VeeR (Pin 8) is the ground for the receiver section. What is the maximum operating temperature for the HFBR-1414TZ? The maximum operating temperature is typically 85°C. What kind of optical fiber should I use with this transceiver? The HFBR-1414TZ is compatible with multi-mode fiber, specifically for short-range communication. Can I use the HFBR-1414TZ with a single-mode fiber? No, the HFBR-1414TZ is designed for multi-mode fiber and is not compatible with single-mode fiber.How do I know if my module is functioning correctly?
If there is no fault, the TX Fault and RX_LOS pins should both be high, and data signals should be transmitted and received correctly.Can I use the HFBR-1414TZ in both commercial and industrial environments?
Yes, it is designed to work in commercial temperature ranges, typically 0°C to 70°C.How can I interface this transceiver with a microcontroller?
You can connect the TD+ and TD- pins to the microcontroller's TX lines and RD+ and RD- to the microcontroller's RX lines.What is the data rate for the HFBR-1414TZ?
The data rate for this module typically ranges from 1 Gbps to 2.5 Gbps, depending on the application.Is this module suitable for high-speed networking applications?
Yes, it is ideal for high-speed networking, data communication, and other fiber optic applications.What is the typical transmission distance for this optical transceiver?
It typically supports distances up to 550 meters over multi-mode fiber.Can I use the HFBR-1414TZ for long-distance transmissions?
For long distances, you would need a single-mode fiber-compatible transceiver, not the HFBR-1414TZ.Is it necessary to have a separate ground for transmit and receive sections?
Yes, the module uses separate grounds for the transmitter (VeeT) and receiver (VeeR) sections to avoid interference.What is the function of the Vcc pin?
The Vcc pin (Pin 1) supplies the 3.3V power required to operate the module.How does the HFBR-1414TZ ensure reliable data transmission?
It uses differential signaling for both transmission and reception, ensuring reliable, high-speed data transfer.Can I use the HFBR-1414TZ with a SFP or other standard optical interfaces?
The HFBR-1414TZ is not directly compatible with SFP interfaces but can be used with compatible devices that accept the module's form factor and signals.I hope this detailed explanation, along with the pinout and FAQs, helps clarify the usage and function of the HFBR-1414TZ transceiver module.
