The FBR(M)-Serial-2 (SM/ST) is a single-mode with ST connector, rugged, industrial-grade RS232/RS422/RS485 to fiber optic converter that supports asynchronous serial communications (RS232, RS485, and RS422) through multi-drop fiber optic links. The FBR(M)-Serial-2 supports up to 255 fiber nodes, and each node can extend the RS232/RS422/RS485 distance to 25 miles (40 km). Depending on the site situation, the FBR(M)-Serial-2 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. The unit also features redundant power supplies and power alarm outputs for uninterrupted system performance and easy maintenance.

The FBR(M)-Serial-2 comes with the options of ST, SC, and FC connectors for fiber optic links, and it accepts a wide range of industrial DC input (from 12V to 48V DC). The product can be mounted directly on a DIN Rail, without a need of using any unsecured DIN-Rail brackets or adapters.
