Description These miniature data modems transport an RS232, RS422, or RS485 data signal on a pair of fibers. Available in multimode and single-mode versions, they are packaged in a D-Sub
connector-size package. These units can be mixed and matched to provide both optical data transmission and data type conversion with one link. All units operate on two fibers.
