FIB-485A-M,adam RS485 / RS422 to RS232 to multi-mode fiber converters schematic

     The FIB-485A-M is RS485 to fiber optic converter, distance and speed of optical fiber transmission arent related. Serial-interface fiber transmission resolves the contradiction of copper transmissions long-distance and high-speed communications because of its advantages such as high reliability, security and confidentiality and so on. The use of fiber as communication transmission medium completely solves the problems such as electromagnetic interference, ground loop interference and lightning damage. It has been used more and more in industrial automation, distributed data acquisition, intelligent transportation, electricity, water, banking and many other areas and become the preferred option for communications transmission.

      FIB-485A-M is an industrial grade RS485/422/232 to fiber converter of Fourstar. It achieves RS485, RS422 or RS232TXDRXDGNDsignals transparent transmission on fiber, without changing the original communication protocols and software, plug and play, and directly replace copper Conductor transmission.
