8 Channel RCA Audio over Fiber Extender

View : 609
Type : RCA Audio to Fiber Converter
Description :

This 8 port RCA Audio over Fiber Extender enables the transmission of audio, serial data, DI/DO, and Ethernet signals over a single-mode optical fiber.


The 8 * RCA audio to fiber converter uses digital encoding technology and features an RCA (phono) audio interface. It enables the transmission of audio, serial data, DI/DO, and Ethernet signals over a single-mode optical fiber, allowing distortion-free bidirectional communication over a maximum distance of 100 km. The audio interface employs 24-bit AD/DA and 128K sampling, ensuring professional-grade transmission quality. The device consists of an optical transmitter and an optical receiver, which can be configured as either 4-channel bidirectional audio or 8-channel unidirectional audio.


All-digital fiber optic transmission platform, the multi-service platform with a flexible configuration.

The audio interface is RCA (phono), and the audio power supply is provided by a high-power toroidal transformer with +-18V power, offering a high dynamic range.

The data and audio interfaces provide 3-level lightning protection, capable of passing the ITU-T K.21 (10/700 μS) common mode: 6KV impedance (40 Ω) test.

It supports single-fiber transmission, with the option for dual-fiber configuration.

It can detect the absence of fiber, indicating power loss or fiber breakage in the remote device.

The audio component utilizes 24-bit AD/DA 128K sampling, guaranteeing professional-grade transmission quality.

It supports bidirectional asynchronous data transmission (forward and reverse).

The asynchronous data transmission rates range from 110 to 115.200 Kbps or higher.

Asynchronous data can be RS232/RS485/RS422/Manchester code.
