FO modem is a type of RS-232/RS-485/RS-422 serial port fiber optic Modem. It adopts industrial standard design and its wall type outface design supports DIN-rail standard lead rail installation, featuring easy installation. Presently, many users make use of RS-232/RS-485/RS-422 serial port fiber optic Modem to solve the electromagnetic interference in engineers and to extend the RS-232/RS-485/RS-422 serial port transmission distance to several or even tens of kilometers.
KINGTON-modem can provide users with RS-232/RS-485/RS-422 serial port end-to-end transparent transmission. Since signals are transmitted over fibers and these optical signals are free of electrical conductivity, they have strong anti-interference capacity and are immune to high-voltage power or thunders.
Features:
- Zero-Delay automatic forwarding
- Supporting three types of interfaces: RS232/485/422
- Automatic detection of serial port rate, judgment and control of data transmission direction
- Working wavelength: 850 nm (multi-mode); 1310 nm (single mode)
- Maximum communication rate: 500 Kbps
- Optional optical interfaces: ST/SC/FC
- Up to 2 kilometers in multi-mode transmission and up to 40 kilometers in single mode transmission
- Broad voltage inputs: 5-40 VDC or 85-265 VAC
- The interface supports 1500W surge protection and 15KV ESD protection
- External power supply
