RS232 and RS422 Fiber Data Modem

RS-232 Fiber Optic Data Modem for Point-to-Point or Star Networks

The IFS D9100E series consists of fully-digital transceiver units designed for implementing point-to-point or star traffic signalization/ communications data networks. These environmentally hardened units are ideal for use in unconditioned out-of-plant or roadside installations and may also be utilized in channelized linear drop-and-repeat communications networks as either the local end-of-line transceiver unit or as the master beginning-of-channel device. Optional battery back-up capability provides the highest level of network reliability in the event of loss of local 115 VAC prime operating power. Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required. LED indicators are provided for rapidly ascertaining equipment operating status, and these units are available in either stand-alone or rack mount configurations.
