Description :
This device utilizes digital encoding technology, with an RCA audio interface, allowing for long-distance bidirectional transmission of audio signals.
Overview
Features
● A fully digital fiber optic transmission platform that allows for flexible configuration of multiple services on the same platform.
● Various options are available, including standard desktop, mini desktop, and rack-mount configurations.
● It utilizes a proprietary large-scale integrated circuit core with independent intellectual property rights.
● The data interfaces and audio interfaces are equipped with three-level lightning protection, capable of passing the ITU-T K.21 (10/700 μS) common mode: 6KV impedance (40Ω) test.
● It supports single-fiber transmission, with the option to select dual-fiber transmission.
● It is capable of detecting the absence of a fiber signal, indicating power failure or fiber breakage at the remote end.
● The audio transmission utilizes 24-bit AD/DA and 128K sampling, ensuring high-quality broadcast-grade transmission.
● It provides bidirectional asynchronous data transmission (both forward and reverse).
● The asynchronous data transmission supports rates above 110-115.200 Kbps.
● The asynchronous data can be in RS232/RS485/RS422/Manchester code format.
