0.25mm G657A2 50.4km/Spool Raw Optical Fiber

0.25mm G657A2 50.4km/Spool Raw Optical Fiber. Ultra low attenuation and wide transmission band Attenuation <=0.21 dB/km at 1550 nm, supports 1285 to 1625 nm full wavelength range, suitable for long haul backbone and 100G/400G high speed transmiss. Low PMD and excellent fiber compatibility PMD <=0.15 ps/sqrt km, standard 9.2+/-0.4 um MFD, ultra low splice loss, compatible with existing G.652 fiber networks. Superior macro bend performance and high mechanical strength Macro bend loss <=0.05 dB at 20 mm 1 turn, 100 kpsi proof test, tensile strength >=4.0 GPa, prevents fiber breakage during cabling. Stable performance in harsh environments Induced attenuation <=0.03 dB/km after temperature cycling, damp heat, water immersion and dry heat tests, fit for outdoor and coastal FTTH projects.
