Categories G.652.D, Optical Fiber, Products, Single Mode Fiber Optic
Low water peak non-zero dispersion shifted G.652.D single mode optical fiber. Which complies with or exceeds the standard of ITU-T G.652D and IEC60793-2-50 B1.3 type optical fiber. It is applied to the transmission system of full wavelength from 1260nm to 1625nm. It eliminates the assimilating water peak induced by OH- @ 1383nm of standard single mode optical fiber, and enlarges the work windows to E wavelength (1380nm-1480nm). The optical fiber eigenvalue of attenuation and dispersion is optimized at all wave length, which satisfies the transmission demand of multiple channel and high speed.
