Product Description
The ANT401-50/CU1N is a high-speed optical communication interface designed by Yokogawa to extend the reach of the ESB (Extended Serial Backplane) bus in CENTUM VP control systems. This module acts as a critical signal repeater, converting electrical signals into optical pulses to enable long-distance I/O expansion. By utilizing fiber optic media, the ANT401-50/CU1N provides complete electrical isolation between the Field Control Station (FCS) and remote I/O nodes, effectively eliminating ground loop issues and protecting the system backbone from lightning surges or high-frequency electromagnetic interference.
Designed for high-availability architectures, the /CU1N version indicates specific connector and functional enhancements for modern FIO (Field Interface I/O) environments. The module facilitates a deterministic 128 Mbps transmission rate, ensuring that remote process data is synchronized with the central processor with negligible latency, even over distances spanning several kilometers.

Network Topology and Integration
The ANT401-50/CU1N is typically installed in the Field Control Unit (FCU) as the Master-side repeater. It must be paired with an ANT502 module at the remote I/O node side to convert the optical signal back to electrical for the FIO modules. This setup is the industry standard for distributed plant architectures where I/O racks are located in separate buildings or remote marshalling areas far from the central control room.
Technical FAQ
-
Question: What is the primary benefit of using the ANT401-50/CU1N over standard copper ESB cables?
Answer: The primary advantages are distance and isolation. Copper ESB cables are limited to 10 meters, whereas the ANT401-50/CU1N extends this to 5 km while providing immunity to electrical noise and lightning-induced surges. -
Question: Does the /CU1N suffix impact the type of fiber optic cable I should use?
Answer: The suffix generally relates to connector and revision details. For ANT401-50 series modules, multi-mode fiber (GI 50/125 µm) is the standard requirement to maintain signal integrity over long distances.
