Radiation hard Singlemode Fibers

j-fiber introduces its enhanced version of radiation hard Singlemode fiber. It shows excellent recovery times after pulsed and continues irradiation with doses of up to 3000rad. Compliant to G.652.B, the fiber has been optimized to operate in the 1310nm and 1550nm window. Ideal for applications which require shortest recovery times such as in military plane systems or ground communication. In addition the fiber is also available in our 500µm coating design for rugged cable constructions.
