How many categories are there for buffered fibers?



As one looks at individually buffered fibers there are two general categories. First a loose tube which is typically a large rigid tube whose ID is many times the diameter of the coated optical fiber.

  • This is commonly called “black cable” such as outside plant cables that are hold fibers (typically 24 to 288 fibers in one cable) and many fibers are in one “tube” These are usually terminated in a splice case and are protected by a UVcoating placed on the glass at drawing.

A Second is a tight buffer that is in intimate contact with the coated optical fiber.  

  • This is the most common type of buffered fiber to be connectorized.
