Layer 3 TSN Switch Revolutionizes Industrial Operations with Seamless Connectivity

The Layer 3 TSN Switch is an indispensable tool for modern industrial operations seeking seamless connectivity and precise synchronization. Equipped with six-gigabit ports and two high-speed 2.5/10G SFP+ ports, data flows effortlessly at lightning speed, facilitating efficient communication between connected devices. Advanced IEEE time synchronization protocols such as 802.1 AS, 802.1Qbv, and 1588v2 guarantee that all devices are perfectly synced for real-time control applications. Additionally, features like layer 3 routing, unicast/multicast support, and seamless redundancy capabilities enhance network resilience while authentication via RADIUS and TACACS+ safeguards against unauthorized access. In essence, the Layer 3 TSN Switch offers the precision timing and unwavering uptime essential for today’s smart factories and industrial IoT networks – enabling businesses to achieve unparalleled network synchronicity digitally.

Top Features to Look for When Choosing a Layer 3 Ethernet Switch

The Layer 3 TSN Industrial Switch is a robust and versatile networking device designed to operate in extreme temperatures ranging from -40 to +75℃. With ±8kV Power Supply Surge Protection, this switch offers reliable performance even in harsh environments where power surges are common. Its impressive 64 Gbps Switching Bandwidth ensures fast and efficient data transfer rates, making it ideal for high-demand applications. Additionally, the switch features a generous 32Mb Packet Buffer, allowing for smooth and uninterrupted data flow without any delay or packet loss. Whether used in industrial settings or outdoor installations, the Layer 3 TSN Switch is a dependable solution for all your networking needs.

Layer 3 TSN Switch offers Seamless Protection Switching

TSN Ethernet Switch keeps your data flowing seamlessly by detecting failures in the network and automatically switching traffic to the backup link, then back again once the primary link is restored. Ideal for applications that cannot tolerate any disruption in transmissions like industrial automation, transportation systems and military networks that require continuous uptime. Fault protection done right, so your business can run at full speed ahead.

APS Protection

APS is a linear protection mechanism. With APS configured, a protection link is reserved for a working link. If a signal failure or degradation occurs on a working link, its traffic is switched to the protection link.

Media Redundancy Protocol

Media Redundancy Protocol (MRP)  provides a recovery time of 10ms or less, fault tolerance, and load balancing. Ease of set-up and high-speed performance make Ring topology networks.


Ethernet ring protection switching helps achieve high reliability and network stability. Links in the ring will never form loops that fatally affect the industrial network operation and service availability. 

Monitor and Configure your Layer 3 TSN Switch via CLI, Web and SNMP

Take complete control of your network by utilizing the versatile Fiberroad TSN Switch. With console, web, and SNMP interfaces, this switch offers multiple methods for monitoring, configuring, and securing your network. The console interface grants direct access through CLI commands for advanced troubleshooting and configuration, while the web interface presents a user-friendly graphical dashboard. Additionally, SNMP support allows for seamless integration with network management systems and tools. These robust management features provide you with full visibility and command over network performance, allowing you to optimize uptime and productivity. As for security purposes, the switch employs various technologies to mitigate risks such as unauthorized access, data tampering, and system intrusions. Whether you are an IT professional or a network engineer, this adaptable switch delivers real-time network oversight and cybersecurity solutions to effectively manage and safeguard your network.
