Recommendation ITU-T G.652 (08/2024)
This Recommendation describes a single-mode optical fibre and cable which has zero-dispersion wavelength around 1310 nm and can be used in the 1310 nm and 1550 nm regions.
Optical Fiber Types
ITU G.651 Covers multimode 50/125 micron graded-index fiber. ITU G.652 Covers single-mode NDSF (non-dispersion-shifted fiber). This fiber is in most of the cable that was installed in the 1980s.
