FEATURES
When you need to connect full- or half-duplex async computers
and terminals, choose the Async Fiber Optic Mini Modem. A pair of
these modems can drive data over multimode fiberoptic cable up to
2 miles (more than 3 km) at data rates up to 19.2 Kbps.
Special circuitry allows the modem to operate without external
power, by deriving ultra-low power from the DTE data and control
signals on the interface.
Two models are available:
• Async Fiber Optic Mini Modem with (2) fiberoptic ST connectors
and (1) DB25 female connector (part number ME605A-FST)
• Async Fiber Optic Mini Modem with (2) fiberoptic ST connectors
and (1) DB25 male connector (part number ME605A-MST)
And you can configure the modem for continuous or controlled
carrier to suit your application.
Setting the modem for DCE or DTE operation is a breeze, too.
Simply move the handy DCE/DTE switch to the desired position.
NOTE: Must be used in pairs.
OVERVIEW
Typical Application
Connect an async computer to an async terminal via a pair
of Async Fiber Optic Mini Modems.

Switch-selectable DTE/DCE
The Async Fiber Optic Mini Modem features a switch-
selectable DTE/DCE option. This allows operation as DTE,
for connection to another DCE such as a multiplexor port,
eliminating the need for a cross cable.
Continuous or switched operation
The carrier can be strapped for either continuous
operation or switched operation, controlled by the RTS
signal, for transfer of a control signal end-to-end.
