Graded Index Fibers?

Graded Index Fibers

Features

l Standard communication fibers for 850 nm bis 1300 nm

l Low loss, high bandwidth

l Laser power transmission fibers up to 600 μm core diameter

l Better beam profile than step index fibers

l Specialty coatings for high temperatures, high vacuum and harsh chemicals environments

l Radiation resistant type

Properties

l Proof test level (Screen test): 50 kpsi (Communiction fibers)

l Proof test level (Bend method): 70 kpsi (Fiber diameter > 200 μm)

l Bend radius: momentary 100 times the fiber radius long term 600 times the fiber radius
