The Hirschmann BOBCAT BRS20-4TX/2FX-SM-EEC is the extended temperature variant of Hirschmann’s compact 6-port single-mode fiber managed Fast Ethernet BOBCAT switch, combining a -40 to +70°C operating range with two 100BASE-FX single-mode SC fiber uplinks capable of reaching up to 32.5 km — a combination that addresses the specific needs of outdoor energy infrastructure, railway wayside and traction control systems, and utility networks in Nordic and Baltic climates where both thermal extremes and long inter-site fiber spans are routine requirements. Manufactured by Hirschmann, a Belden brand, the switch provides 4x 10/100BASE-TX RJ45 copper ports alongside the two long-range single-mode fiber uplinks in a 57 mm wide fanless PC-ABS DIN rail housing rated to IP30, with dual redundant 12 to 24 VDC power inputs and USB-C local management consuming just 7 W. TSN 802.1Qbv support on interfaces 1/1 to 1/3 delivers deterministic real-time Ethernet communication across both copper and single-mode fiber segments, while the full industrial protocol suite — PROFINET, EtherNet/IP, Modbus TCP, IEC61850 — ensures compatibility with PLCs, SCADA systems, and IEC61850 protection relays used in energy, rail, and utility infrastructure. Redundancy capabilities include HIPER-Ring, MRP (IEC62439-2) as both client and manager, RSTP, LACP, Link Backup, and Redundant Network Coupling, supporting high-availability topologies spanning both media types. Security features encompass Secure Boot, signed firmware, 802.1X port access control, RADIUS authentication, VLAN-based ACLs, and DoS prevention. Vibration and shock compliance per IEC 60068-2-6 and IEC 60068-2-27, an MTBF of approximately 2.64 million hours, and a 60-month guarantee confirm the BRS20-4TX/2FX-SM-EEC’s fitness for demanding long-lifecycle outdoor and field deployments.
