Fiber Modem
1. HiOSO FM280 fiber modem is a kind of RS-232/RS-485/RS-422 serial fiber optic modem. It is designed to meet industrial standard. When applied to industrial control equipment, this product can extend the transmission distance of control data so as to realize remote control.
2. Wall-mounted design supports DIN-rail installation, which makes installation really convenient. Thus far, many users have utilized the fiber modem to solve the problem of electromagnetic interference in projects. Additionally, RS-232/RS-485/RS-422 serial transmission distance can be extended to several kilometers or even tens of kilometers.
3. FM280 can provide users with port-to-port transparent transmission among RS-232, RS-485 and RS-422 serial ports. Due to the adoption of fiber optic transmission, optical signals transmitted through fiber cables cause no electrical conductivity. With ultra strong anti-jamming function, the fiber optic communication system is not affected by thunder, lightning, or high voltage electricity.
