DrakaElite Specialty Fibre
RadHard 50/125 µm
SI-Multimode Fibre
This DrakaElite
TM
RadHard 50 µm core diameter Step-Index multimode fibre (SI-MMF) is part of Prysmian
Group’s growing family of radiation hardened fibres for applications from telecom to industrial.
Low bandwidth RadHard Step-Index multimode fibres are available, upon request, in different core diameters and
with various numerical apertures. In this data sheet two types are indicated.
Coating
DrakaElite
TM
RadHard Step-Index multimode fibres are coated with a dual layer UV curable Acrylate, type DLPC9.
The coating is designed for tight-buffer cable applications, demonstrating a high resistance to micro-bending. The
coating offers an excellent stable coating strip force over a wide range of environmental conditions and coating
stripping leaves no residues on the bare glass fibre. In tight buffer applications the entire coating construction (tight
buffer and primary coating) can very easily be stripped off.
For higher temperatures other coatings are available (e.g. high temperature Acrylate, up to 150 C)
