Product Description
The ANT401-5E is a high-performance optical regeneration module designed for Yokogawa’s proprietary ESB (Extended Serial Backplane) bus system. It converts electrical ESB signals into fiber-optic pulses, effectively eliminating the distance limitations of copper cabling while enabling secure, high-speed communication between local and remote I/O nodes in distributed control systems.
Engineered specifically for RIO (Remote I/O) bus expansion, the ANT401-5E provides galvanic isolation between ESB segments, significantly reducing the risk of surge damage, ground potential differences, and electromagnetic interference (EMI) in large-scale industrial plants.
The module is typically deployed in pairs or in conjunction with the ANT502 optical interface module to establish reliable long-distance links between the Field Control Station (FCS) and remote racks within the Yokogawa FIO architecture.

Application Scenarios
Remote I/O Expansion
Connects remote I/O racks located in separate process buildings to a centralized Field Control Station.
Site-wide ESB Integration

EMI/RFI Mitigation
Uses fiber-optic transmission to maintain signal integrity in high electrical noise environments.
FAQ
Can the ANT401-5E be used with multimode fiber?
The module is optimized for singlemode fiber to achieve the full 5 km transmission range. Multimode fiber may reduce the supported distance significantly.
Does this module support hot-swapping?
Yes. Within the Yokogawa FIO system architecture, hot replacement is supported when redundant ESB configuration is properly implemented.
What is the difference between ANT401 and ANT411?
The ANT401-5E is the standard optical ESB repeater. The ANT411 typically refers to a slave-side optical module or a hardware variant with different environmental specifications.
