Industrial Grade 4 Channel Serial Data Fiber Optic Modem

View : 523
Type : Serial Optical Fiber Modem
Description :

This product provides 1-4*RS232/422/485 in optical fiber transmission and supports point-to-point communications. On this basis, the networking is a more complex network topology, with self-healing ring network protection.


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.
