12.2.2.1 Optical Fiber Specifications
Merging recommends the use of multimode 50/125 um fiber (62.5/125 um can also be used). Up to 2km long fibers can be used.
12.3 AES-EBU, AES-EBU II, SDIF, TDIF I/O Daughter Card
The Mykerinos AES-EBU Daughter board offers 24 channels of digital I/O over 12 AES-EBU input and output pairs. 8 channels
feature real-time Sampling Rate Conversion from 32 to 192 kHz (up to 96 kHz for AES v.1), which may be inserted either in the
input or output signal path under software control. Signals on the wires can be carried at nominal speed (up to 48kHz), twice the
nominal speed (up to 96kHz) and four time the nominal speed (up to 192kHz, only supported on AES II), allowing up to 12 channel
pairs at 96kHz “single wire” on the AES and 12 channel pairs at 192kHz “single wire” on the AES II. These modes are software
controlled. Connections are made through three DB-25 connectors (one primary on the daughter card itself, two additional connectors
on separate ribbon cables). This option includes three DB-25 to XLR cables. Special versions with either SDIF or TDIF format
instead of AES-EBU may also be offered.
