SECURE AUDIO

SKU FS-SAUD-RCA-E

SECURE AUDIO EXTENDER RCA

Secure remote deployment: This solution provides encrypted audio transmission between distant computers, servers, and workstations, ensuring data protection in sensitive environments.

Fibre-optic security infrastructure: Leverages optical transmission technology to provide tamper-resistant, interference-immune connectivity. The system employs fibre-optic architecture to prevent signal interception, electromagnetic interference, and unauthorized monitoring, ensuring data integrity.
Plug-and-play deployment: Enables instant operability without additional software or complex configuration requirements, streamlining implementation in secure environments.
Preserved audio integrity: Retains original audio quality during transmission, ensuring highfidelity sound while maintaining the one-way secured audio blocker

The FS-SAUD-RCA-TX accepts the source audio on RCA, converts it to optical transmission and sends it through the fiber link. The FS-SAUD-RCA-RX converts the optical signal back to analog audio and outputs it on RCA.

One-Way Signal Path

The datasheet explicitly lists unidirectional data transmission.

Fiber-Based Separation

The link converts analog audio to optical transmission between the two endpoints.

EMI-Immune Optical Path

Fiber transport avoids electromagnetic interference along the optical link.

No Reverse Analog-Audio Channel

TX provides audio input; RX provides audio output.
