Product Details
This DrakaEliteTM RadHard single-mode fibre (SMF) can be used for high irradiative environments (e.g. gamma rays, X-flash, neutrons protons) up to a dose of about 10 kGy. For extreme irradiative environments (some MGy dose) DrakaEliteTM Super RadHard SMF is recommended. Note: 1 Gy = 100 Rad.
This Germanium-doped RadHard SMF has been qualified and approved by the U.S. Defense Supply Center, Columbus (DSCC) in accordance with the U.S. Military MIL-PRF-49291/7 specification. (Note: 500 μm coating is not qualified).
Because Radiation Induced Attenuation (RIA) is a strong function of time after dose, dose rate, temperature, system operational wavelength, and system operational power, assessing the RIA performance of fibres should be conducted as close to conditions in the final application as possible.
The DrakaEliteTM Germanium-doped RadHard SMF can be used in all cable constructions, including loose tube, tight buffered, ribbon and central tube designs. This fibre complies with or exceeds ITU-T Recommendation G.652.D, IEC 60793-2-50 category B1.3 Optical Fibre Specification and Telcordia GR-20-Core.
Prysmian Group’ fibre plant Draka Comteq Fibre B.V. in Eindhoven , Netherlands, is MIL-STD-790 certified.
