Overview
The transmission of analog audio is realized by adequately sampling the audio signal in the 20 Hz to 20 kHz bandwidth, and coding appropriately for digital transmission. Various impedance options exist for audio source and load – balanced 600 Ohm, Blanaced Hi-Z (Low-Z on output), and Unbalanced Hi-Z (Low-Z on output).
The digital audio standard frequently called AES/EBU, officially known as AES3, is used for carrying digital audio signals between various devices. It was developed by the Audio Engineering Society (AES) and the European Broadcasting Union (EBU) and first published in 1985, later revised in 1992 and 2003. Both AES and EBU versions of the standard exist.
Optiva Series - Professional Media Transport
Audio Over Fiber
Optiva® audio is a perfect solution for transmitting a variety of audio formats over long or short distances with a single wavelength. This single fiber, single wavelength solution is perfect for any situation in which audio must be transported over a distance greater than 300 meters without suffering any loss of fidelity. Transmission without amplification or regeneration up to 70 km is achievable. Up to 4 independent duplex analog audio or 8 stereo digital audio signals may be transported with a single Optiva insert card. The space available for half of these audio signals may instead be used for analog or digital video, or data as well.
Another unique capability of this system is that it utilizes Optiva's patent-pending Daisy Chain™ Technology. This gives system designers the flexibility to add additional Optiva insert cards, for the purpose of transporting additional video, audio, and/or data signals over the same fiber.
System Design
Switching and multicasting the Optiva audio cards (as well as all other Optiva signal cards) over the OptiLinx® Switching Platform is straightforward, making this the perfect solution for any system architecture that requires arbitrary reconfiguration of audio and video sources and A/V monitors.
Optiva® insert cards are supported by both 19" rack mount and compact tabletop or wall mountable enclosures. The 3RU 19" rack mount enclosure (Model: OT-CC-16-100) can support up to 16 insert cards plus dual-redundant hot-swappable power supplies (Model: OT-CC-16-100-RPS). Also available in the 19" rackmount form factor is the 4-slot (Model: OT-CC-4-1U) which houses 4 insert cards in 1RU of rack space. The compact one slot (Model: OT-DTCR-1) and two slot (Model: OT-DTCR-2) enclosures are useful for remotely deployed signals. The desktop enclosures require an external power supply (Model: PS-9012).
