INTRODUCTION

The OLSON TECHNOLOGY, INC. Model OTDL-FOM-01 RS-232/422/485 Serial Fiber Optic Modem is ideal to con-

nect RTU to HOST or SCADA controllers via optical fiber. The equipment is resistant to the effects of lightning strikes,

power surges, and other electromagnetic interference, providing a reliable data network. The Model OTDL-FOM-01

meets IEA/RS-232 transmission standards at data rates up to 115.2kb/s and RS-422 and RS-485 transmission standards at

data rates up to 500kb/s. The transmission distance is 20km using dual single-mode fibers.

Features include:

• Asynchronous point-to-point data rate of up to 115.2kb/s (RS-232) and 500kb/s (RS-422 and RS-485).

• RS-422/485 port supports 32 nodes with options for up to 128 nodes.

• 1310nm wavelength single-mode transmission up to 20km on two fibers.

• Auto test signal rate and zero delay auto transmit capability.

• Surge protection up to 1500W with 15kV static protection.

• DC power from +9 to +25 Volts.

• Industrial temperature range from –25°C to +70°C.
