16 Channel RCA Audio over Fiber Optical Converter

The 16-channel RCA audio over fiber converter utilizes digital coding technology and features an RCA (phono) audio interface. It enables the transmission of audio, data, dry contact, and Ethernet signals over a single-mode optical fiber for long-distance bidirectional communication. It is capable of transmitting signals without distortion or the need for relays for distances up to 100 km. The device consists of an optical transmitter and an optical receiver, and it can be configured to support either 8 channels (4 stereo) bidirectional audio or 16 channels (8 stereo) unidirectional audio, depending on the requirements.

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

● The device supports single-fiber transmission with the option for dual-fiber transmission.

● It is able to detect the absence of fiber reception, indicating remote device power failure or fiber breakage.

● The audio utilizes 24-bit AD/DA 128K sampling, ensuring broadcast-grade transmission quality.

● The device provides bidirectional asynchronous data transmission (forward and reverse).

● Asynchronous data transmission rates of 110-115.200 Kbps or higher.

● Asynchronous data can be RS232/RS485/RS422/Manchester coding compatible.
