EtherCAT Fiber Optic Switch

EtherCAT fiber optic switches and media converters enable high-speed, long-distance, and interference-resistant EtherCAT communication over optical fiber networks. OverviewEtherCAT fiber optic devices are used to extend EtherCAT networks beyond the limitations of copper cabling, providing long-distance communication, high immunity to electromagnetic interference (EMI), and support for complex topologies such as star or redundant networks. These devices include fiber-optic junctions, media converters, and couplers, which convert signals between copper and fiber or between different fiber types.

Key Devices and Features1. EK1521 1-Port EtherCAT Fiber-Optic Junction (Beckhoff)Supports multi-mode fiber with SC duplex connectors. Enables EtherCAT star topologies and modular star hubs.

Converts 100BASE-TX to 100BASE-FX in combination with an EtherCAT Coupler like EK1100. Supports distances up to 2 km with multi-mode fiber. Can be used in redundant optical fiber systems for high reliability.

2. CU1521 / CU1561 EtherCAT Media ConvertersCU1521: Converts between copper and multimode or single-mode fiber, supporting long-distance links. CU1561: Converts between copper and plastic optical fiber (POF), ideal for easy field installation.

Operates bidirectionally and collision-free with constant delay. Supports fast link control and fault-tolerant EtherCAT strand closure. Configurable via a switch for Link Loss Forwarding and normal Ethernet operation.

3. ECAT-2511 Series (ICP DAS)Converts EtherCAT signals to single-mode fiber while reshaping signals to compensate for distortion. Provides bus isolation to prevent errors from wire shorts or disturbances.

Enables secure data transmission and reduces susceptibility to EMI/RFI interference. Allows cost-efficient fiber utilization, potentially doubling the use of existing fiber infrastructure. 4.
