AFI MR-05E-S Audio Fiber Optic Module Receiver, Single-Mode, 12 VDC

Extend clear, low-noise line-level audio across long distances for security, surveillance, and monitoring applications with the American Fiberteck MR-05E-S Audio Fiber Optic Module Receiver. This standalone media converter receiver accepts 600 Ω balanced or unbalanced line-level audio and converts optical signals from single-mode fiber back to wired audio using FM modulation for superior signal-to-noise performance and consistent output across the optical loss budget. Powered by 12 VDC and equipped with diagnostic LEDs for audio level, DC power and optical presence, the MR-05E-S eliminates field adjustments and reduces commissioning time—saving labor and minimizing downtime.

The unit uses an ST optical connector for reliable fiber links and is compatible with AFI 05B transmitters and American Fibertek rack cards, enabling flexible integration into monitoring, intercom, public address and security audio systems. Its transparent audio path preserves fidelity for recording and surveillance applications while providing the robustness required in critical infrastructure environments.
