RS232 / RS485 / RS422 / Serial To Multi-Drop Fiber Optic Converters
-
Our advanced, rugged, industrial-grade, RS232 / RS485 / RS422 serial to multi-drop fiber optic converters are designed to cover large areas. These converters support up to 255 fiber nodes, and each fiber node can extend the RS232 / RS422 / RS485's distance to 3 miles (5km) for multi-mode converters and cables, or 25 miles (40km) for single-mode converters and cables. Depending on the site situation, these multi-drop fiber optic converters can be configured as a daisy-chain or a self-healing redundant ring fiber network. When configured as a ring fiber network, the built-in self-healing feature allows the data to be transmitted clockwise or counterclockwise; therefore, failure of any individual converter will not affect other devices located on the same fiber ring, making the entire data network more robust and reliable. These multi-drop fiber optic converters have been designed for harsh industrial environments and withstand a wide temperature of -40°F to 185°F (-40°C to 85°C), and they come with the options of multi-mode and single-mode, and ST, SC, and FC connectors.
