Option Board MADI I/O, Optical (O_DAP_MO_MM_a, O_DAP_MO_SM_a)

Standards

  • Relevant specifications comply with AES10-2008 and AES11-2009

Audio

  • 24-bit, transparent forwarding of PCM and compressed audio

  • Sample rate = 44.1, 48, 88.2, 96kHz (88.2, 96kHz short framing)

Important - Not all sample rates are supported by the host system, please refer to the respective information.

Optical Input, LC

  • 64/56 channels @ 44.1 and 48kHz; 32/28 @ 88.2 and 96kHz

  • Connector type = LC (IEC 61754-20)

  • Center wavelength = 1310nm (typical), 1270 ... 1360nm

  • Input optical power

    • O DAP MO MM a = -31 ... -8dBm, OM2 multimode (50/125um)

    • O DAP MO SM a = -23 ... -8dBM, singlemode (standard values, others upon request)

  • Cable length maximum

    • O DAP MO MM a = 1.5km, OM2 multimode

    • O DAP MO SM a = 2km, singlemode (standard values, others upon request)

BNC Output

  • Optical and BNC outputs carry the same signal

  • Impedance = 75Ohm

  • Output voltage = 0.6Vpp (typical) @ 75Ohm

General Features

  • Field-replaceable optical module (SFP)

  • Reference-grade Wordclock recovery, master-sync capable

  • Dedicated routing for non-processed channels

  • All channels (maximum 64) can be routed to/from the device or looped through

  • AES3 channel status management, non-audio detection

  • Parallel outputs (BNC/LC) for media conversion
