16-Port RCA Audio over Fiber Converter

The device adopts digital encoding technology with RCA audio interfaces. It can achieve long-distance bidirectional transmission of 16 audio signals through a single-mode optical fiber, with a maximum distortion-free transmission distance of 100 km. The audio interface uses a 24-bit AD/DA converter with a sampling rate of 128 kHz, capable of delivering broadcast-grade transmission. It consists of a transmitter and a receiver and can be configured in either an 8-channel bidirectional audio or a 16-channel unidirectional audio mode.

● The device features a 19-inch 1U aluminum alloy anodized casing with an IP40 rating.

● The audio interface of the device uses RCA unbalanced interfaces, providing a high dynamic range.

● The audio interface of the device offers three-level lightning protection functionality and can pass the ITU-T K.21 (10/700 μS) test with a common mode of 6KV and impedance of 40 Ω.

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

● The audio quality is ensured with a 24-bit AD/DA converter and a sampling rate of 128 kHz, delivering broadcast-grade transmission quality.

● The device can be powered by AC 220V or DC -48V/+24V power supply.
