Olycom Compact 4 Port 100M Fiber Network Switch

Key Features of 4 Port Ethernet Switch

1. Designed for Fiber-First Industrial Topologies

The IM-FS220FE is particularly well suited for fiber-centric industrial network designs, where copper is only used at the edge. With two independent SFP fiber ports, the device allows engineers to build simple yet effective redundancy without introducing management complexity. Whether deployed in a ring, dual-homing, or point-to-point topology, the switch ensures that critical communication paths remain available even if one fiber link is disrupted.

This design philosophy makes the IM-FS220FE ideal for installations where stability and predictability are more important than advanced software features—such as unmanned sites, roadside cabinets, or legacy industrial systems.

2. Stable Performance Without Configuration Risk

As a fully non-managed switch, the IM-FS220FE eliminates configuration errors, firmware dependencies, and software maintenance cycles. Once powered on, it immediately forwards traffic using a store-and-forward architecture, filtering corrupted packets and maintaining consistent throughput under burst conditions.

The generous memory resources (128M DRAM and 4Mb packet buffer) allow the switch to absorb temporary traffic spikes caused by polling systems, alarms, or sensor bursts—ensuring reliable communication even in time-sensitive industrial processes.

3. Built to Withstand Electrical and Environmental Stress

Industrial environments often expose network equipment to voltage fluctuations, electromagnetic interference, and extreme temperatures. The IM-FS220FE is engineered to operate reliably under these conditions, combining 6KV Ethernet surge protection, EMS Level 3 immunity, and a rugged metal enclosure.

Its wide operating temperature range (-40℃ to 75℃) enables deployment in outdoor cabinets, trackside enclosures, substations, and factory floors without the need for additional cooling or environmental control systems. This significantly reduces both deployment and long-term operational costs.

4. Simplified Power Integration for Industrial Cabinets

The wide DC12–52V power input allows the switch to be powered directly from common industrial power sources, including control power supplies and backup battery systems. Reverse polarity protection further safeguards the device during installation and maintenance.

With low power consumption and compact DIN-rail form factor, the IM-FS220FE fits naturally into space-constrained control cabinets, making it easy to standardize across multiple sites and projects.

5. An Ideal Choice for Reliability-Critical Edge Networks

The IM-FS220FE is best positioned as a reliability-focused edge switch, bridging field devices to fiber backbones without introducing management overhead. It is particularly suitable for:

Industrial systems requiring dual fiber paths without managed switching

Remote or unmanned sites where maintenance access is limited

Legacy automation networks migrating gradually from copper to fiber

Infrastructure projects prioritizing long lifecycle and operational simplicity

By combining redundant fiber connectivity, industrial-grade protection, and plug-and-play operation, the IM-FS220FE delivers a balanced, low-risk networking solution for demanding industrial environments.
