Fire Resistant Central Loose Tube Optical Fiber Cables
Application
Marine optical fiber cables are designed to data transmission in ship and specially in cruise ship where low
smoke, halogen free and fire resistant cables are required to increase safety on board, suitable for flexible
installation on and below deck of commercial ships without constant exposure to oil, grease and other
lubricants.
