Industrial Grade 4 Channel Serial Data Fiber Optic Modem

Provides 1-4*RS232/422/485 in the optical fiber transmission, supports point-to-point communications, and on this basis, the networking is more complex network topology, with a self-healing ring network protection. The product breakthroughs contradictory legacy serial interface communication distance and speed, but also solve electromagnetic interference, ground loop interference, and lightning damage problems, significantly improving the reliability of data communications, security, and confidentiality.

● Based on a proprietary integrated circuit;

● Provide 1-4independent serial ports (RS232/422/485 optional) channel, physical isolation from each other,  there is no correspondence between the

● Support point-to-point network topology loop between the bus and the device; 

● while using optical isolation technology, isolation and internal communications bus data signal, Effective protection of the communications equipment from power surges and ground loop interference and sabotage 

● RS232/485/422 interface, optional three data, RS232 supports 3-wire RS232 (TXD, RXD, GND), flow control support CD, DSR, CTS,

● RS232 / 485/422 channels can be transmitted from0-115.2KBP Sasynchronous serial data adaptive

● Serial port interface lightning reach IEC61000-4-5 (8 / 20μS) differential mode: 6KV, impedance (2Ω); Common mode: 6KV, impedance (2Ω) standard
