Product Overview
The FQ-MOD268 Series RS485 Fiber Optic Converters are industrial communication converters designed to extend RS485 data signals over fiber optic cable for reliable long-distance transmission.
The converter supports 1-channel RS485 asynchronous data transmission in point-to-point applications, with communication rates of up to 120Kbps. RS485 electrical signals are converted to optical signals for transmission over single-mode or multimode fiber, providing reliable communication with strong resistance to electromagnetic interference.
The series supports a wide range of fiber configurations, including multimode dual-fiber, single-mode dual-fiber, and single-mode single-fiber transmission. Optical interfaces are available in SC, FC, and ST, with transmission distances from 2km to 20km depending on the selected configuration.
The compact 95 × 70 × 25mm enclosure is suitable for industrial automation, control systems, remote data acquisition, and other RS485 communication applications.
