4 Channel Audio XLR over Fiber Converter

The device uses digital encoding technology, and the audio interface is XLR. It can transmit audio signals, data signals, dry contact signals, and Ethernet signals bidirectionally over single-mode optical fiber for up to 100km without signal distortion. The audio interface adopts 24-bit AD/DA 128K sampling and has transmission quality suitable for broadcasting. The device consists of an optical transmitter and an optical receiver, and can be configured as either 2-channel bidirectional audio or 4-channel unidirectional audio.

● IP40-rated aluminum alloy anodized shell;

● The audio interface is XLR balanced interface;

● Desktop-type, 4U rack plug-in type can be provided in various ways;

● Single-fiber transmission, dual-fiber is optional;

● Audio adopts 24Bit AD/DA128K sampling, studio-level transmission quality;

● The audio interface provides 3-level lightning protection function and can pass the test of ITU-T K.21 (10/700 μS) common mode: 6KV impedance (40Ω).
