The ComNet™ FTA/FRA2C1 Series audio multiplexer provides the transmission of two
audio signals and one contact closure over one multimode or single mode optical
fiber. A bidirectional model, FXA2C1(M,S)1, is also available. 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.

These extenders are designed for long-term, reliable operation in harsh industrial
environments, and a fault-specific LED indicator is provided for rapidly ascertaining
the operating status of the extender and the link. See Figure 9 on Page 5 for an
explanation of LED indicators.

Packaged in the exclusive ComNet ComFit housing, these units may be either wall or
rack mounted. See Figure A on Page 6 for mounting instructions.

See Figures 1 – 9 for complete installation details.
