This Thor Broadcast F-4A-TxRx 4 Unbalanced Uni-Directional Audios over 1 fiber Transmitter and Receiver Kit helps solve sending unbalanced audio over long distances using Fiber.
We have several diferent models supporting 2, 4, 8,16 and 32 analog XLR Audio.
The audio fiber optic Transmitter, converts analog Audio 20hz to 20Khz fiber optic modulated digital stream so it could be transported over single mode or multimode fiber. (long haul available) - XLR to Optical
The Optical Receiver with XLR outputs converts the optical signal back to its orginal Analog Wave form - Optical to XLR
Offers very low latency 1ms so it's perfect for live events, shows, concerts, auditoriums, etc
The small and compact form factor means it could be used for any applications where copper has a limited distance or noise issues.

Why not buy this Thor Broadcast F-4A-TxRx 4 Unbalanced Uni-Directional Audios over 1 fiber Transmitter and Receiver Kit today?
How many audio channels does the F-4A-TxRx carry, and in which direction?
A: The F-4A-TxRx carries four unbalanced analog audio channels over one fiber. Transmission is unidirectional, from the transmitter to the receiver.
How far can the standard F-4A-TxRx transmit over single-mode fiber?
A: The standard configuration supports distances up to 20 km over 9/125 µm single-mode fiber. Longer-distance configurations are described separately, so the standard model should not be specified for a longer run without confirming the optical configuration.
What optical connector and wavelength should the fiber installation accommodate?
A: The standard optical connection is ST/PC, operating at 1310 nm. Other connectors and 1550 nm or CWDM options are available by request, so the fiber termination and optical plan should match the selected configuration.
What audio impedance and signal levels should connected equipment support?
A: The audio inputs and outputs are specified as 600 ohms, unbalanced. The listed audio level is 0 dBm, with audio voltage up to 2 V peak-to-peak; use these specifications when checking compatibility with source and destination equipment.
What sampling rate and bit depth are used for audio transport?
A: The specified sampling rate is 48 kHz with 24-bit resolution. The transmitter converts analog audio into a digital optical stream, and the receiver converts it back to analog audio.
What power specifications should be used when planning the installation?
A: The listed power requirement is 5 V DC, with power consumption specified as 3 W. The documentation does not clarify whether the consumption figure applies to each endpoint or the complete link.
What operating temperature range is specified?
A: The specified operating temperature range is -20°C to +75°C. Keep the equipment's installation environment within that range.
Is the F-4A-TxRx suitable for live-event audio where delay matters?
A: Yes. The documented latency is approximately 1 ms, making it a suitable option for live events, concerts, shows, and auditoriums that need four channels of one-way analog audio transport.
Can this system replace a long copper audio run between locations?
A: Yes. It transports four unbalanced analog audio channels over fiber and restores analog audio at the receiving end. It is intended for applications where copper cabling is limited by distance or noise issues.
Is the F-4A-TxRx the right choice for a two-way intercom link?
A: Not when the link needs to carry audio in both directions. The F-4A-TxRx is explicitly a one-way transport model, so a two-way intercom application needs a bidirectional solution.
