Industrial PoE Network Switch with Optical Fiber Bypass

The New Generation Managed Industrial PoE Network Switch with 8-Port 10/100/1000Base-TX provide reliable Ethernet transmission. To prevent fibre network communication during power loss, The Industrial Switch has built-in 2-channel SC/FC/ST connectors for optical bypass. A managed industrial PoE network switch with optical fiber bypass supports various management functions, including Rapid Spanning Tree, Multiple Spanning Tree and Ethernet Ring Protection Switching (ERPS) protocols for network redundancy. The IGMP facility can handle the multicast traffic commonly used in Video Surveillance deployments.

Optical Fiber Bypass Layer 2 Switch for Industrial Networks

Fiberroad L2+ Managed Industrial PoE Network Switch, was designed for industrial Power over Ethernet networks. It offers Layer 2 switching functions and Layer 3 static routing features in such a rugged enclosure. Industrial Ethernet switches operate consistently at temperatures between -40 and 75 degrees, allowing DIN rail mounting or wall mounting to utilize cabinet space efficiently.

Extreme PoE Networks Switches are Useful in Harsh Environments

Despite its IP40 Durable Aluminum housing, no fan design can provide efficient heat dissipation. Industrial Power over Ethernet switches are commonly found on plant floors or curb-side traffic control cabinets, where electromagnetic interference and heavy electrical surges are protected. It is also equipped with an integrated power supply source (9–56V DC) for worldwide high availability applications requiring dual or backup voltage inputs. Indeed, The design of the switch ensures operates in Harsh Environment.

Maintaining PoE over Fiber Networks is Simple and Fast

Integrated 2 simplex ST/SC/FC connectors with 2-channel optical bypass. Fiber connections are supported in the optical fiber ports with speeds of 1Gbps. It automatically switches optic network traffic to prevent link failure during power loss. Additionally, it allows the local network switch to be replaced or removed without any downtime.

Establish a Secure Network with L2+ Industrial Gigabit Switches

FR-7M3208F provides robust Layer 2+ Gigabit networks connectivity, including but not limited to Static route, LAN network security, ACL/QoS policy… Moreover, By configuring ITU-T G.8032 ERPS (Ethernet Ring Protection Switching) technology, Spanning Tree Protocol (802.1s MSTP), and redundant power system in industrial automation networks to enhance system reliability and uptime in harsh environments. As can be seen, the Managed Industrial Switch is easy to manage and maintain.

Stay Connected to the Industrial Network any time, anywhere

Managed Industrial PoE Network Switch allows various network management methods, such as the WebGUI, CLI and NMS. Easy to use, especially without additional hardware investment and installation. An industrial PoE network switch can manage a network on a central level, manage the bandwidth allocation, monitor the bandwidth, and monitor performance in real-time.

SSH2.0 and HTTPS/TLS protocols are used to provide powerful protection against network threats. In addition to DHCP Snooping, IP Source Guard, ARP Inspection Protection, 802.1x port-based and MAC-based network access control, user hierarchical management, SNMPv3 authentication, and so The Industrial Network Switch administrator can now construct highly-secure corporate networks with considerably less time and effort than before.
