AFI MT-05E-S Audio Fiber Optic Link Module Transmitter

Deliver clear, reliable audio over fiber for security and monitoring systems with the American Fiberteck MT-05E-S audio fiber optic link module transmitter. Designed for single-direction line-level audio transmission, the MT-05E-S sends 600 Ω balanced or unbalanced signals over singlemode (or multimode) fiber using FM modulation to maintain a consistent output level and improved signal-to-noise ratio. That transparency makes it ideal for surveillance audio, remote intercoms, perimeter monitoring and distributed PA systems.

Installers benefit from a true plug-and-play media converter: ST optical connectivity, no user adjustments, and a compact standalone form factor speed deployment. Built-in diagnostics for audio level, optical presence and DC power provide quick visual health checks so technicians can resolve issues faster. The module also integrates with AFI SR-20 card cages for scalable rack installations.

Choose the MT-05E-S when you need dependable, low-maintenance audio over fiber that integrates seamlessly with security, CCTV and monitoring infrastructure. Contact your distributor to specify the MT-05E-S for your next surveillance or audio-over-fiber project.
