VDS Rail's 28 ports 10 Gigabit Ethernet Fiber Optic Consist Switch is a 10Gigabit/Gigabit/Fast Ethernet managed switch EN 50155 compliant, designed for network applications in Rolling-Stock environments.

Layer2/Layer 3 managed switch

Besides providing wire-speed layer 2 forwarding capabilities, this switch also supports Layer 3 services, allowing IPv4 unicast and multicast routing among different VLANs. Layer 3 extensions include inter-VLAN routing with packet filtering together with NAT. OSPF and RIP dynamic protocols are also supported.

Besides the standard features provided by this class of devices, this Consist Switch provides advanced software facilities for onboard network discovery and configuration.

Wide range of models available 

The Consist Switch has two (2) 10GBASE-SR/SW multimode OM3 fiber optic* ports, three (3) 10GBASE-T ports, eleven (11) 1000BASE-T ports and twelve (12) 100BASE-TX ports (*Other fiber optic types are available on request).

Four (4) Gigabit Ethernet ports and twelve (12) Fast Ethernet ports can be equipped with PoE+ capability.
