AFI MT-05E Multi-Mode Audio Fiber Optic Link Module Transmitter

Deliver clear, dependable audio where it matters most — the American Fiberteck AFI MT-05E Multi-Mode Audio Fiber Optic Link Module Transmitter converts line-level audio into a robust optical signal ideal for security, surveillance, and monitoring applications. Designed as a media converter/audio extender transmitter, the MT-05E supports single-direction line-level audio at 600 Ω (balanced or unbalanced) and operates over multimode or singlemode fiber using ST connectors. FM modulation preserves signal-to-noise ratio and maintains consistent audio output across the optical loss budget, while onboard diagnostic indicators (audio level, DC power, optical presence) provide fast system status checks to minimize downtime. The transmitter requires no user adjustments at installation, streamlining deployments for integrators and system installers. Compact standalone or rack-card form factors make it simple to scale from single links to centralized rack installations. Ideal for CCTV audio links, remote paging, and long-distance monitoring, the AFI MT-05E delivers professional-grade audio performance for critical infrastructure.
