• Supports Multi-Forwarding modes – Store and Forward, (Switching Converter) Modify Cut-through, Pure Converter and Converter with Auto Change modes
• Supports Auto MDI/MDI-X, Auto Negotiation
• Supports Multi-mode 2KM, Single-mode 30KM
• Extreme Low Data Forwarding Latency- 1.6 x 10-6 Sec
• Auto Link Loss Forwarding (LLF) for fault detection
• Fault Alert for port and power
• Redundant 10~60V DC Power inputs with DC polarity protection
• Supports AC 1.5KV Hi-Pot isolation protection
• EN 50121-3-2 Railway EMC compliance (applying)
• Operating temperature -25~75°C (-40~75°C wide operating temperature model available by request)
