Passive Fibers
Passive fibers
Since the discovery of ZBLAN glasses in 1974, Le Verre Fluoré has worked to develop a large range of fluoride optical fibers, including ZrF4, InF3 and AlF3 based optical fibers, designed for mid-infrared applications.
Our fluoride fibers can be separated in three main categories :
ZFG (Zirconium ZrF4 Fluoride Glass) = fluorozirconate fibers
Exhibit a high transparency from 0.3 up to 4.5µm (see graph below)
IFG (Indium InF3 Fluoride Glass) = fluoroindate fibers
Exhibit a high transparency from 0.3 up to 5.5µm (see graph below)
AFG (Aluminium AlF3 Fluoride Glass) = fluoroaluminate fibers, generally used for end-capping solutions. Contact us to know more about AFG.
Multimode fibers
Cut-back background losses:
- ZFG: Typ < 20dB/km at 2560nm
- IFG: Typ < 20dB/km at 3670nm
Operation wavelengths (<1dB/m):
- ZFG: 0.32-4.3µm
- IFG: 0.335-5.3µm
Those fibers can be drawn in many kind of design depending on your needs, click on the category you are interested in to find out more :
