A:
Yes, definitely. It is designed specifically for RS485, RS422, and RS232 serial transmission over fiber. The 850nm multimode link provides full electrical isolation, so heavy motor interference will not affect your signal at all, even across distances up to 2km. By

Finding reliable 2Mbps industrial-grade SFP modules for specialized protocol gear can be tricky. We plugged these into our hardened switches across our water treatment facility. Even with significant motor vibration and daily temperature shifts, the transceivers maintain a clean, stable link without dropping any telemetry packets :D
