As the inventor and owner of the technology for placing optical
fibers into stainless steel tubes, AFL Telecommunications 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. AFL’s stainless steel tubes are suitable
for use as a component in aerial applications such as Optical Ground
Wire or for buried applications. Typical excess fiber length values
are 0.30% with higher values available upon request. The most common
sizes and fiber counts are shown in the linked PDF specifications
document to the right. For custom sizes, fiber counts or application
information, contact customer service.
