Patton FiberPlex TD-7280 Line Level Stereo Audio Extender over Fiber Optics

Patton Electronics TD-7280 Line Level Stereo Audio, Serial, and Control Extender over Fiber

The feature-rich FiberPlex TD-7280 from Patton Electronics is a powerful problem solver when it comes to routing audio or transporting ear and mouth (E&M) signals. It converts and combines line-level stereo analog audio with serial and control data and transmits it over a fiber-optic SFP module. It’s ideal for long or short-haul transport. Along with audio, a multi-format serial data connection (RS-232/422/485) and a bidirectional pair of Form C contact closures are included. The combination of audio and signaling provides an elegant solution for 4-wire E&M, push-to-talk, intercom, audio distribution, and railway signaling applications.

Advanced routing and networking options may be enabled with a DIP switch setting. In Point-to-Point Mode, audio inputs are mapped directly to audio outputs on the opposite unit, giving serial data and contact closures a direct connection. In Broadcast Mode, one unit is configured as the master, which sets the clock and sampling rate. Analog and serial signals to the master are sent to all slave devices, which output the data on their respective ports. No communication is sent from the slaves to any other units. In Intercom or “Loop mode”, one unit is configured as the master, which sets the clock and sampling rate. It polls the loop, with each unit in the loop adding its input to the aggregated sample, gated by its push to talk, if enabled. When the sample returns to the master, it then sends out that aggregated sample as the output for all units in the loop. All units forward the aggregated output around the loop until it returns to the master, which discards it. Serial data from the master is replicated on all slaves, and serial data from the slaves is aggregated to output on the master.
