A pair of modems ensures integrity of data expensive and heavy shielding, and • Full or half duplex transmission over fiber optic cable at data complex error checking routines • Operates over multimode or single rates up to 64 kbps. Almost absolute security and reduction in mode fibers • FOM-6AV can operate as DTE or DCE. the cost of data encryption When configured as DTE, FOM-6AV can be • Transfers one control signal end-to-end Eavesdropping is virtually impossible as connected to a DCE such as a multiplexer • Operates as DTE or DCE negligible power is radiated from the fiber port, eliminating the need for a cross-cable. The carrier can be set for continuous or Safety and electrical isolation: no spark • Plugs directly into V.24/RS-232 DTE switched operation controlled by the RTS hazard and no ground-loop noise connector signal for transfer of a control signal problems. end-to-end. A LED indicator lights whenever • LED indicator for data transfer data transmission takes place. • No external power required • Innovative circuitry allows FOM-6AV to operate without connection to the mains • Compact, lightweight, easy to install supply, by using ultra-low power from the data and control signals. FOM-6AV operates even if only Transmit Data is connected, i.e. no control signals or any other source of APPLICATION power are required. • FOM-6AV is furnished in a miniature plastic enclosure. • Digital Interface Declaration of Conformity SPECIFICATIONS V.24/RS-232 integral 25-pin, male or female • Data Rate Mfr.
