## Summary description

Audac OPT2 is a fiber optic adapter with an ST/PC connector designed for multi-mode fiber links. Supplied as a single unit (1 pc), it provides a physical interface for joining or extending multi-mode optical cables in network, audio-visual, or data transmission installations. Suitable for patch panels, wall plates and field termination.

## Long description

Audac OPT2 ST/PC multi-mode single-pack is a fiber optic adapter designed to provide a reliable physical interface for joining or extending 62.5/125 µm multimode optical cables with ST/PC connectors. Supplied as a single unit, the OPT2 is intended for use in network, audio-visual and data transmission installations and serves as the fiber interconnection module for the R2 and M2 Digital Multi-Zone & Multi-Media Matrix Systems. It enables transfer of up to 16 digital audio signals (8 stereo channels) over a single duplex multimode fiber link and is suitable for patch panels, wall plates and field termination.
Advantages
The OPT2 supports multimode duplex fiber with ST/PC termination and includes the required software and mounting accessories (fiber cable excluded). Its design allows cascading of multiple devices (up to 15) in a closed-loop wiring principle to cover extended distances with stable digital audio transport. The dedicated protocol ensures accurate, low-latency signal transmission and reliable zone assignment and routing via the system user interface. The single-pack format simplifies inventory and installation where only one fiber interconnection point is required.
Suitable for
Linking R2 and M2 matrix system units over multimode fiber
Extending audio or data signals between rooms or floors in buildings
Integration into patch panels and wall plates for AV installations
Field termination points where a single fiber adapter is needed
Key specifications
Connector type: ST/PC (duplex)
Fiber type supported: Multimode 62.5/125 µm
Audio channels over single fiber: Up to 16 digital signals (8 stereo channels)
Cascading capability: Up to 15 devices in series
Maximum link distance between devices: Up to 1000 meters (multimode link segments)
Includes: Adapter module, software and mounting accessories (fiber cable not included)
How to use
Install the OPT2 module into the designated slot of the R2 or M2 matrix system or mount it at the chosen termination point such as a patch panel or wall plate. Use a duplex multimode 62.5/125 µm fiber terminated with ST/PC connectors to link the devices. Wire the system following a closed-loop principle: connect output to the input of the next device and continue the chain until the final device, which feeds back to the input of the first device. Configure channel selection and zone assignments through the matrix system user interface and verify the link status and signal routing after completing physical connections.
Usage recommendations
For best performance and compatibility, use a duplex 62.5/125 µm multimode fiber with ST/PC connectors (for example Procab FBS125 Duplex Fiber Optic ST/PC to ST/PC 62.5/125µm). Ensure connectors are clean and properly seated, follow the closed-loop wiring scheme for cascaded installations, and maintain single-segment distances within recommended limits to preserve signal integrity.
