The model F282xD products are fiber optic modems designed to extend an RS-530 signal over fiber. These modems can also be used as a four channel synchronous/asynchronous data multiplexer, are DTE/DCE switch selectable, and can interface with the VERSITRON M62xxD/M82xxD Fiber Optic Micromodems.

A Model F282xD link uses fiber optic cable of up to 2Km for 1310nm multimode optics and 20Km for 1310nm singlemode optics. The link has a maximum data rate of 5 Mbps, providing synchronous, asynchronous or isochronous full-duplex or simplex data transmission with fully transparent operation. The Model F282xD FOM II modems support the interface control signals associated with the EIA/TIA RS-530, RS-422, RS-449, V.35 and MIL-STD-188-114A standards. This is accomplished by multiplexing the control signals along with clock and data signals and transmitting this serialized signal to the remote unit. At the remote unit the signal is de-multiplexed and applied to the interface.
