High Quality Unbalanced RCA Audio to Fiber Extenders, 1Pair (TX and RX)

Overview

This Unbalanced analog audio optical transceiver is a single chip stereo analog data fiber optical converter that uses bit-stream converter (ADC) technology.The low power consumption and low voltage requirements make the device ideal for use in low-voltage and low-power portable data and audio devices.

Features:

This unit can extend Unbalanced RCAAudio over an optical fiber cableto far end. It allows 1-16 audio device synchronous transmission, No Step uprequired.RCAAudio signal is transmitted from T (TX) in the direction of R (RX). offerirectional 1-8 is optional

Compatible withSinglemode and Multimodeoptical fiber cable. Singlemodesingle fiberup to 12.4 miles (20Km), Mutlimodesinglefiber up to 0.31 miles(500meters).

LEDs for power supply and optical fiber link status indication which can monitor the operating status of the system.

Typically used in applications for Campus, public places, Staging, Theaters, Stadiums, Parks, Broadcast, studio audio and more. and are available for stand-alone and desktop type, or wall mounted, installations.

No need to set up ,Simply plug in an Optical FC port and RCAaudio connectors at TX and RX sides,
