Overview

The MODHUB‑16EF from Contemporary Controls is part of the MODHUB series of ARCNET hubs, designed to expand and stabilize ARCNET networks in demanding industrial environments. Unlike the standard MODHUB‑16E, the 16EF variant integrates fiber optic expansion, enabling long-distance, EMI-immune communication. It supports baseband ARCNET at 2.5 Mbps, and its modular design allows mixed media connections, including coaxial, twisted pair, and fiber.

Technical Specifications

Key Features

• Fiber optic capability: Enables long-distance, EMI-immune communication.
