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.

Unmanaged Ethernet Switches
-
CommFront offers a range of rugged, industrial-grade, managed and unmanaged Ethernet Switches. These Industrial Ethernet Switches 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 10/100/1000M for both Fast and Gigabit Ethernet networks. In addition, our advanced, rugged, industrial-grade, Fast and Gigabit Ethernet Switches support both point-to-point and multi-drop (daisy-chain or self-healing redundant ring) fiber optic networks, which are designed to cover large areas. These industrial Ethernet Switches support up to 255 fiber nodes, and each fiber node can extend the Fast and Gigabit Ethernet data up to 100 miles or 160 km. When configured as a ring network (managed Ethernet Switches), the built-in self-healing feature allows the Ethernet data to be transmitted clockwise or counterclockwise; therefore, failure of any individual converter will not affect other devices located on the same ring, making the entire Ethernet network more robust and reliable.
