Replace Complex IV Couplers with Light-Speed Links OptiLiFi™ replaces traditional Inter-Vehicular (IV) couplers with a light-based high-speed link, creating a train-wide gigabit backbone for control, video, and diagnostic data. Designed for legacy rakes and new trainsets, it offers secure, interference-free, and maintenance-free connectivity with a simple 2-hour retrofit per coach.
What is LiFi?
LiFi (Light Fidelity) uses light waves instead of radio frequencies to transmit data. It provides massive bandwidth, ultra-low latency, and zero electromagnetic interference. Because light stays confined to its path, LiFi is naturally secure, eco-safe, and license-free—ideal for train environments.
Superior to Wire & Wireless — Key Benefits
No Mechanical Wear
Eliminates moving contacts — no physical wear or mechanical failures.
No Interference
Light-beam link stays contained — immune to Wi-Fi/GSM congestion.
High Reliability
Stable, predictable performance over wired & RF alternatives.
Zero Maintenance
No batteries or moving parts to replace; low lifecycle cost.
Instant Alignment
Quick optical alignment — reduces installation time.
Electrically Isolated & Safe
No conductive contact — safe for passengers and equipment.
Stable Throughput
High-bandwidth backbone carrying CCTV, control & analytics without dropouts.
