RS232/485/422 to Fiber Optic Modem

RS232/485/422 to Fiber Optic Modem Profile：
Optic Modem transmits RS485/232 Serial data over optical fibers.The Optic interface SC/FC/ST, multi-mode or single mode dual fiber.The fiber optic data modem solve the traditional RS485/232 to signal transmission distance short and poor anti-interference ability, and also solve the electromagnetic interference, ground loop interference and lightning and voltage surges problems, greatly improving the reliability of data communication, security and confidentiality.
RS485 to Fiber Optic Modem point to point used, achieve serial datalong distance transmission. Widely used in Telecom room, LED display communications, security surveillance, intelligent transportation systems, electric power monitoring, environmental monitoring.
