Figure 2 D-422-MG-C1 Connector module.
The D-422-MG has a dedicated connector module: D-422-MG-C1. This module is
mounted at the rear of the sub-rack. The module is shown in figure 2. Note that this
connector module always occupies two (2) slots in the sub-rack.
To set up a link, two D-422 modules must be used. The RS-422 data cable is connected to
RS-422/E1 on each of the D-422 modules. The two modules are connected to the fibres
with one fiber from TX on module 1 to RX on module 2, and from RX on module 1 to TX
on module 2. The TX UPG connector contains an electrical version of the modulated
signal running on the fiber. This connector is used for future upgrade with a flashlink
multichannel DWDM system.
