Lantech industrial switches adopted for Lærdal Tunnel

Lantech industrial switches adopted for Lærdal Tunnel
Project Introduction
Lærdal Tunnel is a 24.51 km (15.23 mi) long road tunnel of European route E16 and located approximately 175~200 km (109–124 mi) north-east of Bergen, the second-largest city in Norway. The E16 is the main road between Norway's two largest cities Oslo and Bergen, which makes Lærdal Tunnel one of the most important tunnels in Norway. The tunnel was opened in 2000 and it is still the longest road tunnel in the world currently.

System Requirements

  • Provide reliable networking service 24/7/365
  • 802.3 at PoE+
  • Redundant ring protection
  • Easy installation and effortless maintenance
  • Sustain from wet climate of western Norway and harsh environment in cabinet

Western Norway is one of the wettest regions in Europe. It has milder winter than other parts of Norway, with rain being more common than snow in the winter.
