Cable cut off wavelength4/2/2024 ![]() ![]() Users still focus primarily on attenuation, maybe dispersion, as critical propagation properties.ĭue to relatively new operating wavelength requirements below 1310 nm, some astute end users are taking a renewed look at cutoff wavelength specifications. Although fiber manufacturers and some fiber users are aware of cutoff wavelength, it’s not as famous a parameter. However, buried in the fine print of fiber specs is a parameter called cutoff wavelength. Take an intro to fiber course, and you’ll learn about attenuation, dispersion, fiber geometry, maybe fiber strength. CUT-OFF WAVELENGTH MAKES A COMEBACK IN IMPORTANCE This latest article will help the user to understand what “cut-off wavelength” is, why does it matter and how is it measured. Article 4 featured single-mode fiber geometries and now the latest release from OFS – Article 5, deals with “Cut-off Wavelength” (COW). Article 2 concentrated on the several types of dispersion that exist in fiber today, closely followed by Article 3 – Fiber strength and reliability. ![]() The first Article in this series focused on growth in bandwidth demand and attenuation in optical fibers. ![]()
