Allen-Bradley 1783-ETAP2F EtherNet/IP Copper to Fiber Media Converter

Brief Product Description

The Allen-Bradley 1783-ETAP2F is a high-performance EtherNet/IP tap designed to bridge copper and fiber optic industrial networks. This module facilitates reliable data transmission in electrically noisy environments by providing a seamless transition between one RJ45 copper port and two fiber optic LC ports.

Functional Overview

The 1783-ETAP2F serves as a critical networking component within the Rockwell Automation Stratix family, specifically engineered to extend EtherNet/IP connectivity over long distances. By utilizing fiber optic technology, this device eliminates ground loops and electromagnetic interference that typically degrade signal quality in large-scale industrial plants. It supports Device Level Ring (DLR) topologies, which provides network resiliency and ensures that a single point of failure does not result in total system downtime.

Network Integration and Performance

This EtherNet/IP tap implements auto-negotiation and auto MDI/MDI-X detection on the copper port, which simplifies installation by allowing the use of straight-through or crossover cables. The dual fiber ports operate at 100 Mbps and provide a 12.8dB power budget, maintaining a receiver sensitivity between -31.8dBm and -14dBm. Consequently, engineers can deploy this module in vast manufacturing facilities where copper distance limitations of 100 meters are insufficient. Furthermore, the unit supports full and half-duplex communication modes to accommodate various industrial hardware requirements.

Installation and Environmental Durability

The open-style enclosure supports standard DIN-rail mounting, allowing for both vertical and horizontal orientations depending on panel space availability. Because the module possesses a ruggedized construction, it withstands significant mechanical stress and operates in high-humidity environments (5-95% non-condensing). Proper clearance is required during installation to accommodate the fiber cable bending radius and ensure adequate airflow for thermal dissipation. Transitioning to fiber through the 1783-ETAP2F effectively future-proofs industrial infrastructure against electrical noise and signal attenuation.
