4.1 FIBER CONNECTIONS
The Model 1110 short range modems are designed to work in pairs. You will need one at each end of a dual fiber cable. This cable connects to each Model 1110 using either an ST or an SMA connector. Figure 4 (below) shows a close up of each of these connector types.

4.2 RS-232 CONNECTION
Because the Model 1110 is designed to behave as either a DCE or a DTE device, it does not need special cables to operate. Always use a
