| H-PCF Applications in Traffic / Transportation |
Traffic Surveillance camera systems
Today, many traffic surveillance cameras have problems in video data transmission to Traffic Management Center due to limited transmission capacity of existing cables. H-PCF plays an important role in video transmission.

Vehicle Detection
Fiber optic sensors under pavement have a great potential in future Vehicle detection in intersections or other road. H-PCF is good solution with its high strength & longer transmission length than all plastic fiber.

Electric Toll Collection
Recently, electric toll collection on expressways, like EZ-PASS in New York area collects worldwide interests. H-PCF plays an important role of the system to transmit data from a network terminal to antennas which are located on a communication gates that vehicles passes through to avoid an error caused by thunder bolt or other electromagnetic influence.

Railroad car control
H-PCF and SUMILINK DF series provide good isolation characteristics between high power switching devices, such as a GTO or an IGBT, and its gate control logic circuit. A railroad car's inverter motor uses such devices.

Display boards in train stations or Highways
Display boards on the platforms in train stations or Highways indicating destinations or departure times are very important sources of information for people. H-PCF plays an important role in achieving high reliability, reduction of wiring, and long-distance data transmission.
