Structure for filling in a tube for producing a fibre optic cable includes a cross section of a stainless steel tube designed as a semi-circle in its top half with a large radius.

摘要

A cross section (12) of a stainless steel tube (10) is designed as a semi-circle in its top half (12') with a large radius (R). On the top cross section's apex there is a weld seam (14) welding the lengthwise edges of a stainless steel band. The lower half (12'') runs into a curved part with a small radius (r) and is shaped like a pear. The lower cross section (12'') is almost completely filled up by the filling-in tube (30) for fibre optic cabling.
