Tips: Features of Fiber Converter.
1. Two forms of power interface are provided at the same time, terminal method and socket method, whichever can be connected in actual use.
2. Provide power and signal direction (← and →) three indicator lights to facilitate users to check the communication status.
3. The shell is made of metal and iron, which is sturdy and durable. It can be installed on a panel or on an industrial rail.
4. Optical fiber interface adopts dual FC (FIBER-TX, FIBER-RX) interface.
5. The physical interface of the serial port is in the form of 12-hole binding posts.
6. The serial port provides RS232, RS422 and RS485 three interfaces at the same time, which has a wider application range.
High performance serial to fiber converter supports RS-232 asynchronous protocol, the fiber converter with transmission rate 460 kbps, supports maser-slave mode, transmission distance 4000m (multimode mode), 20000m (single mode), operating wavelength 1310 nm. The fiber optic converter is suitable for power system automation, traffic control and other departments.
