RS-232 solution
Introduction
Mainstream RS-232 fiber optic modem is with two optical fibers connection, we can customize dual fibers modem and single fiber modem, moreover, single mode modem and multimode modem are also available for customization. Our RS-232 fiber optic modem can communicate with RS-485 fiber optic modem directly without extra RS-232 to RS-485 converter, at the same time, point to point connection, bus connection, electric to fiber star connection and fiber to fiber star connection are available.
The main type of our RS-232 fiber optic modem is wall-mounted type and miniature type, DIN-rail type is also available for customization. Wall-mounted type is default type.
The following is basic connection of our RS-232 fiber optic modem:
Dual fiber RS-232 fiber optic modem:
Single fiber RS-232 fiber optic modem:
