FIBER-OPTIC CONVERTER CARD
The Fiber-Optic Converter Card allows networked ARIES Control Units to be interconnected
using fiber-optic medium. Use one OCC to terminate each end of a fiber-optic communications-
channel(s) segment. The ARIES networking structure supports a mixture of fiber-optic and
twisted-wire interconnections among networked control units.
Specifications for the Fiber-Optic Converter Card are provided in Table 2-4.

The OCC Cabinet should be located as required in the same room as its parent Control Unit for
convenient wiring connections (24 VDC and RS485 communications).
Typical Class-B, Style-4 and Class-A, Style-7 interconnections using a mixture of media are
shown in Figures 2-36 through 2-39.
Figure 2-36 shows a typical single-channel system using 62.5/125 m duplex fiber-optic media.
