Once the Model 1193 is properly configured, it is ready to connect
to the fiber interface, to the G.703/G.704 equipment, and to the power
source. This section describes how to make these connections.
The Power, G.703/G.704 and Fiber Line connections are located
on the rear panel of the Model 1193. Figure 5 below shows the loca-
tion of each of these ports.

4.1 CONNECT THE G.703/G.704 NETWORK
There are two ways of connecting to the G.703/G.704 Network.
This section describes both options. After selecting the appropriate
connection, set the internal jumpers as described in section 3.1.2.
4.1.1 Connect the Twisted Pair (120 Ohm) to the G.703/G.704
Network
The Model 1193 is equipped with a single RJ-48C jack for connec-
tions to a G.703/G.704 network. If your G.703/G.704 Network termi-
nates via an RJ-48C, see Figure 6 below.

4.1.2 Connect Coax Cable to the G.703/G.704 Network
The Model 1193 is also equipped with dual female BNCs (TX and
RX) for connection to a 75 ohm dual coax G.703/G.704 Network inter-
face. If your G.703/G.704 Network terminates via dual coaxial cable,
see Figure 7 below to make the proper connections.

4.2 CONNECT THE FIBER INTERFACE

The Model 1193 is designed to be connected to another Model
1193. The Model 1193 supports communication between G.703/G.704
equipment over Single-mode fiber at distances up to 50 km (31 miles).
One modem can connect to another on the end of a single string of
fiber optic cable.
To connect two Model 1193s, use one string of 9/125 micron
Single-mode fiber. The fiber connects to each Model 1193 using either
an FC or SC connector.
Figure 8 below shows a close-up of SC and FC connector types.

WARNING: Model 1193 uses a Laser Diode to transmit invisible light into the fiber. Exposing
eyes to this light can cause permanent damage. To prevent eye damage, DO NOT DIRECT
DISCONNECTED FIBER OR FIBER CONNECTOR OF THE MODEM IN THE DIRECTION OF
THE EYES.
