FEATURES DESCRIPTION • Diagnostics include indication of DTE data receive and transmit status, as well as • FOM-6MP, asynchronous fiber optic • Asynchronous fiber optic modem for streaming detection. multipoint modem, is used for multidrop If FOM-6MP does not receive data from the multidrop data distribution data distribution connecting full or half fiber optic link, the LINK FLT A indicator duplex async computers and DTEs. • Data rates up to 38.4 kbps lights up. If transmission is not received by the remote unit, FOM-6MP sends back a • FOM-6MP ensures integrity of data • Transmission range up to 16 km signal which causes the local FOM-6MP transmission over fiber optic link at distances (10 miles) over single mode fiber LINK FLT B indicator to flash. up to 16 km (10 miles). Only one fiber optic link is required between DTEs for • Automatic disabling in case of streaming • FOM-6MP is delivered in a plastic enclosure transferring data in full duplex. and is powered by an external power supply • Variety of fiber optic interface options, or via the V.24/RS-232 DTE connector. • FOM-6MP is available with a single or dual including single mode, multimode and fiber optic interface. The single fiber optic laser diode over single mode interface modem must be connected to the host (master) and the dual link versions must • Compact, lightweight and easy to install be attached to the slave DTEs. • Wide input DC supply, 10V to 30V • FOM-6MP/DL contains bidirectional optical interfaces and a single V.24/RS-232 DTE interface. Data received on optical link A is sent to the DTE and repeated to optical port APPLICATION link B for transmission to the upstream FOM-6MP. When data is received on link B, it is repeated and transmitted to link A to respond to the master computer's request. • FOM-6MP should be used only in a multidrop application, where data from host (master) is transmitted to all DTEs (slaves), but only one slave responds. The responding DTE contends for transmission either by raising RTS or by data transmission (user-selectable). • To prevent blockage in the event of streaming, a DTE port can be disabled by automatic circuitry, if it remains active for more than 1 or 13 seconds (time interval is user-selectable). The automatic disable resets if DTE RTS drops or data is not being transmitted. SPECIFICATIONS • Indicators Declaration of Conformity Fiber Optic Interface: Mfr.
