Product Highlights
- Transmitter
- Singlemode Fiber
- Unidirectional Audio
- Hot-Swappable
The ST-2A-3 Fiber Transmission System (Transmitter) from Meridian Technologies incorporates an all-digital encoding technology that supports two unidirectional audio channels over one optical fiber. This model uses singlemode fiber. It is well suited for use in intelligent transportation systems, security & surveillance work, access control, among many other applications and settings.
Local indicators provide a visual indication of the status of each audio channel. 3-pin terminal blocks are used for connection of the audio channel interfaces. This series is also compatible with Meridian's SpectraSmart Network management and diagnostic PC-based system.
The DigiSlim product family is available as rack mount cards and modules that can be installed in any of Meridian's desk chassis or in 19" racking frames. This system can be configured in either star (module to rack) or trunking (rack to rack) configurations. These systems can be transformed in to a standalone module by using SR-500/S (standard configuration) or SR-1000/S frames.
