Features:

This unit can extend Unbalanced RCA Audio over an optical fiber cable to far end. It allows  audio device synchronous transmission, No Step up required. RCA Audio signal is transmitted from T (TX) in the direction of R (RX).

Compatible with Singlemode and Multimode optical fiber cable. Single mode single fiber up to 12.4 miles (20Km), Mutlimode single fiber up to 0.31 miles(500meters).

Adopt FPGA, digital coding/decoding and clock recovery technology, high integration and high stability ,it is much better than ordinary one on marketing. 

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 RCA audio connectors at TX and RX sides,
