APPLICATION EXAMPLES
DESCRIPTION
* Optical transmission distance is limited to optical loss of the fiber and any additional loss introduced by connectors, splices and patch panels.
Distance can also be limited by fiber bandwidth. ** For 50/125 Fiber, subtract 4 dB from Optical Power Budget.

All accessories are third party manufactured.
The IFS D1315 series data transceivers provide point-to-point
transmission of full-duplex (4-wire) EIA RS-485 tri-state data signals
over two optical fibers. The transceivers are transparent to data
encoding allowing for broad-range compatibility. When used as a
line-terminating device, these modules are also compatible with the
IFS D2315 series drop and repeat data transceivers. Models within this
series are available for use with multimode or singlemode optical
fiber. Plug-and-play design ensures ease of installation requiring no
electrical or optical adjustments. Each transceiver incorporates power
and transmit/receive data status indicating LED’s for monitoring
proper system operation. The modules are available in either
stand-alone or rack mount versions.
