Fibre optic cabling will be required between the console processor(s) and each outboard I/O Unit – RIO, Alpha-link
LIVE-R, SDI-MADI and MORSE units all use duplex fibre for audio interfacing. Redundant systems will require two
individual fibre links to each outboard unit; see the examples on the following page.
The Alpha-Link 8-RMP microphone amplifiers do not require audio fibre connection to the console. They connect to a local
Alpha-Link LIVE-R unit using analogue and network cabling.
It is a sensible practice to install spare cable runs to allow for system expansion or to replace any leads that may subsequently
become damaged.
The table below details the connectors used to interface the individual I/O units.
!
* MORSE units are fitted with multimode adapters as standard. Singlemode interfaces are available to special order only and
will have extended lead-times.
# $%#$
The default fibre interface adaptors fitted are suitable for multimode fibre connections. RIO stageboxes and MORSE units
may optionally be ordered with singlemode versions for any of the fibre links. (The corresponding port on the console
processor must also be changed to singlemode.) Alpha-Link LIVE is only available with multimode interfaces.
All SSL fibre interfaces use flat (PC) termination not angled (APC).
Singlemode and multimode interfaces and connectors are almost identical in appearance, however, they are operationally
incompatible – the two different standards cannot be mixed for any individual link.
The table below lists the maximum cable lengths permissable for the fibre interface standards available.
