The Fiber Link
The interconnect between the mobile unit and the announce booth is single strand of
single-mode (9/125) fiber. A second fiber may be used to provide backup for the primary
link.
The fiber link uses wdm (wavelength-division multiplex) technology so that data in one
direction uses one wavelength of light and data in the other direction uses a different
wavelength. This allows both directions to be transmitted on a single fiber.
WDM requires that the transmit wavelength on one end match the receive wavelength
on the other end and vice versa.
The ADX-3200 uses standard bi-directional SFP modules, which are accessible by
removing the top cover of the unit.
The wavelengths for the ADX-3200 at the truck should be matched to the wavelengths in
Fiber Ports 1 and 2 of the ADX-8000 Switch in the booth, or other remote switches. Use
ADX-8000 Port 1 for the primary fiber and ADX-8000 Port 2 for the backup fiber. In this
case, the ADX-3200 is operating with all its ports on the PRIMARY network, and the
ADX-8000 will use its port 1 unless that fiber fails, in which case it will switch to port 2.
The ports may be used as all PRIMARY ports (on the primary network), or they may be
configured as PRIMARY and SECONDARY network ports using the ‘Network Config’
function in Dante Controller. This is the redundant network mode.
If you’re not using redundant networks, and you’re using a switch other than the ADX-
8000, only a single connection is allowed to the ADX-3200. Otherwise you will have
created a network loop, and the network will not operate properly.
