The FVT/FVRXA4C1 series audio multiplexer provides the transmission of

contact closure over one multimode or single mode optical fiber. The modules 

use 24-bit 96kHz sample rate digital encoding for superior transmission of 

balanced line-level audio. Plug-and-play design ensures ease of installation 

and no electrical or optical adjustments are required.
