16 Port Serial to Fiber Optic Converter

View : 895
Type : Serial to Fiber Converter
Description :

This device provides 16 channels of RS232/485/422 transmission over fiber optic.


This device provides 16 channels of RS232/485/422 transmission over fiber optic, solving the contradiction between the communication distance and communication rate of traditional serial interfaces. It also addresses the challenges of electromagnetic interference, ground loop interference, and lightning damage, greatly enhancing the reliability, security, and confidentiality of data communication. This product can be widely used in various industrial control, process control, and traffic control applications, and is particularly suitable for banks, power industries, departments and systems with special requirements for electromagnetic interference environments. The RS232/RS485/RS422 channels can transmit asynchronous serial data with a self-adaptive rate range of 0-115200bps.


16 channel serial to fiber converter


The device provides 16 serial ports, with each port supporting optional interface types of RS232/RS485/RS422.

It is equipped with automatic detection of serial port signal baud rate.

The serial interface is designed with lightning protection according to IEC61000-4-5 (10/700μS) differential mode: 6KV, impedance (2Ω); common mode: 6KV, impedance (2Ω).

The serial port can transmit asynchronous serial data with a self-adaptive rate range of 300-57.6Kbps.

The fiber optic interface supports 3 fiber transmission modes: multi-mode dual fiber, single-mode dual fiber, and single-mode single fiber, with optional SC/ST/FC/LC interfaces.

It has multiple power supply options, including built-in AC220V, DC-48V/DC+24V, and DC+V12 power supplies. It supports dual power supply modes such as AC+DC, AC+AC, and DC+DC.
