24B1 Stainless Steel Tube Optical Fiber Unit

 

As the inventor and owner of the technology for placing optical fibers into stainless steel tubes, GL offers a range of tube sizes and fiber counts for a variety of applications. Each tube is flooded with a thixotropic filling compound and hermetically sealed to protect the enclosed fibers from environmental degradation.  This product is sometimes referred to as FIST (Fiber in Steel Tube) or FIMT (Fiber in Metal Tube).
