The OX-377SM-FCAB-D2 data fiber optic MODEM provides 2 channels of RS485 data transmission over optical fibers. This product breaks through the contradiction between traditional serial interface communication distance and communication speed, and also solves the problems of electromagnetic interference, ground environment interference, and lightning damage, greatly improving the reliability, security, and confidentiality of data communication. It can be widely used in various industrial control, process control, and traffic control applications, especially suitable for banks, power companies, and departments and systems with special requirements for electromagnetic interference environments.RS485The channel can transmit asynchronous serial data with adaptive baud rates ranging from 0-115200.

OX-377SM-FCAB-R2 isA multifunctional fiber optic MODEM that supports asynchronous 2-way RS-232 communication interfaces. This device is the best choice for connecting remote terminal units (RTUs) to hosts (HOSTs) or distributed data acquisition system (SCADA) controllers, with a high cost performance ratio. Using ordinary multimode fiber, the effective communication distance can reach 4Km, using ordinary single-mode fiber, the effective communication distance can reach over 40Km, and the communication speed of the serial port can reach 921.6Kbps. Due to the use of optical fiber as the transmission medium, it can completely avoid the threats of lightning, surges, electromagnetic interference, etc. to communication equipment in harsh environments, while eliminating the investment in lightning surge protection equipment when using copper wire
