Feature of RS422 Fiber Modem
The RS422 modem is standalone and rack mountable fiber 1 x 422 modems available in a number of different models, with AC or DC power supplies built-in.
The RS-422 is the standard for longer data transmission distances and higher Baud rates compared with RS232 fiber modem. It is RS422 to fiber converter which realizes transmission of the RS422 signal on fiber.
It easily solved the problem of contradiction between communication distance and communication rate of RS422 port. At the same time, it can be widely used in various kinds of situations, and provide fully transparent operation with data, clock, and common control signals automatically multiplexed. The RS422 Fiber Modem is divided into Dual fiber or Single fiber, the dual fiber optical wavelength up to 850/1310nm and single fiber up to 1310/1550nm.
Advantages of RS422 Fiber Modem
It may be applied in point-to-point applications. The RS422 fiber modem is small and easy use. It easily solves the problem of traditional RS422 communication conflict between distance and rate.
Electromagnetic interfere, lightning interfere, improve the reliability, safety, and security of data communication, suitable for industrial control, procedure control, and traffic control, especially for system in bank, electric, and environment which having special requirement for electromagnetic interfere.
The RS-232, RS-422/ RS-485 fiber modem interface of modem and user’s devices can be connected with each other via the twisted pair. Modem optical port can be connected to another remote modem optical port with the fiber. When the device is connected correctly and working normally, the corresponding LED indicators will be lit or flashing.
Different electrical standard interface can be mixed use. If RS-232 is selected, the maximum transmission distance is 15meters. If RS-485/422 is selected, the maximum transmission distance is up to 1900 meters. Optical port supports ST, SC, FC and other interfaces.
