Product Description

Industrial RS-232 / 485 / 422 serial port optical fiber converter is an optical fiber modem that can provide users with point-to-point transparent transmission of industrial RS-232 / 485 / 422 serial port. It can automatically switch without jumper setting, and can automatically detect the signal rate and automatically forward with zero delay. The product adopts optical fiber transmission, which has many advantages such as isolation protection, good data confidentiality, stable operation and easy maintenance. It effectively avoids the threat of lightning, surge and electromagnetic interference to communication equipment in harsh environment, and can work reliably in harsh and dangerous environment. It can be widely used in various occasions such as industrial control, process control, traffic control and intelligent community. It is especially suitable for banks, electric power and departments] and systems with special requirements for electromagnetic interference environment. According to the needs, the interface mode of optical fiber can be selected, including SC, FC, St, sc20, etc.
