Black Box ICD116A Serial to Fiber Converter, SM ST

Keep critical serial links alive across electrically harsh and distance-limited environments. The Black Box ICD116A converts opto-isolated serial traffic to single-mode fiber, giving you a cleaner path between field devices, control equipment, and remote endpoints. By moving the connection off copper, it helps reduce exposure to EMI, ground potential differences, and the signal degradation that can interrupt legacy systems. This converter is a practical fit for industrial automation, utility infrastructure, and remote monitoring applications where dependable serial transport matters more than convenience. The ST fiber interface supports long-distance deployment over single-mode infrastructure, making it easier to connect equipment that cannot be relocated or replaced. Opto-isolation adds another layer of protection for attached devices, which is especially valuable in plants, substations, and other electrically noisy sites. For teams maintaining installed serial assets, ICD116A offers a focused way to extend service life without redesigning the entire network. It is the kind of component that earns its place in the rack by solving a specific problem well: preserving serial communication where distance, interference, and electrical isolation are non-negotiable.
