Larch Networks acquired great knowledge and experience in developing
Industrial/Rugged switches for customers. The industrial Ethernet switches are designed for use in harsh environments and allow you to build cost-effective, reliable, secure industrial networks.

Whether you require an unmanaged switch for a point to point link, a managed switch for redundancy, our extensive range of industrial Ethernet switches and knowledge of the various standards used in train, railway, energy, utilities and road applications means we have the ideal solution, regardless of the environment.

With the PoE+ sourcing capability end-devices like IP-cameras or WLAN access points can be directly attached to this switch. Alternatively, the switch can be used to power Smart Lighting

Controllers in Smart Building applications (‘Digital Building Switch’). This requires a finless design to optimize long-term reliability (no moving parts) and reduced noise level for mounting into ceilings etc. Different services like Video, Voice, Data, WLAN, Admin, Facility etc. can be separated using different VLANs and interconnected using VLAN bridging on the 10G Switch.
