Product : RS232/RS422/RS485 fo fiber modem,serials to fiber optic modem
The Fiber optic RS232 modem is RS232 to fiber converter which realizes transmission of the RS232 signal on fiber. This product has solved the problem of contradiction between communication distance and communication rate of RS232 port. At the same time, it also has solved the problem of electromagnetic interference, earth link disturbance and thunder/lightning destruction, thus greatly enhancing reliability, security and privacy of data communication. It can be widely used in various kinds of situations such as industrial control, process control and transportation control, and especially suited in bank, electric power as well as departments and systems which have special request to the electromagnetic interference environment.
