  • ITS Traffic Signalization Networks

 


The IFS D1200 series T1 fiber modem data transceivers provides point-to-point transmission of simplex or duplex T1, E1 (CCITT) data signals over two optical fibers. 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, carrier detect and transmit/receive data status indicating LEDs for monitoring proper system operation. The modules are available in either stand-alone or rack mount versions.
