MODULAR FIBER CAMPUS DRIVER, MFCD PLUS

4. Installation

Once the ME621A or ME620A is properly configured, it is ready to connect to the
fiber interface, to the serial port, and to the power source. This section tells you
how to make these connections.

4.1 Connection to the Fiber Interface

The ME621A supports communication at distances to 3 miles (4.8 km) and data
rates to 128 kbps (sync) or 19.2 kbps (async). The ME620A also supports distances
up to 3 miles (4.8 km), but at rates up to 256 kbps (sync) or 38.4 kbps (async).
Figure 4-1 shows the position of the interface connectors on the ME621A or
ME620A back panel.

These short range modems are designed to work in pairs. You will need one at
each end of single 50- or 62.5-micron multi-mode fiber cable. The fiber cable
connects to each ME621A or ME620A using an ST connector. Figure 4-2 below
shows a close-up of the ST connector.
