AFI MT-9P9C 1-Fiber Bi-directional Multi-Mode Contact Module Transmitter

Simplify your security and AV network by carrying audio, control and contact closures over a single multimode fiber. The American Fiberteck MT-9P9C is a 1-fiber bi-directional media converter/audio transmitter designed for surveillance, monitoring and access control systems, delivering up to three channels of 24‑bit digital audio and multi‑protocol data on one strand. With a 21 dB optical loss budget using 1310nm/1550nm wavelengths, the MT-9P9C maintains signal integrity across typical installation distances while reducing infrastructure complexity.

Engineered for reliability, this module is completely transparent to connected equipment—no field adjustments or ongoing maintenance are required. Front-panel diagnostics give instant visual confirmation of audio, data, contact and optical status, and built-in resettable fuses protect power lines to keep critical systems online. Ideal for security integrators, broadcast monitoring, and enterprise AV deployments, the MT-9P9C cuts installation time and simplifies troubleshooting. Add the American Fiberteck MT-9P9C to your surveillance or monitoring projects to consolidate cabling and ensure high-quality, mission-critical audio and control transport.
