'''G.652''' is an international standard that describes the geometrical, mechanical, and transmission attributes of a single-mode optical fibre and cable, developed by the Standardization Sector of the International Telecommunication Union (ITU-T) that specifies the most popular type of single-mode optical fiber (SMF) cable.<ref>{{Cite web|last=ITU|date=2018-01-18|title=Need a wall-outlet connector for FTTH installation?

== History == '''G.652''' was originally developed in 1984 by ITU-T Study Group XV. Subsequently, revisions were published in 1988, 1993, 1997, 2000, 2003, 2005, 2009, 2016, and 2024 (from 1997 as Study Group 15).<ref name=":0" />
== Standard == The standard specifies the geometrical, mechanical, and transmission attributes of a single-mode optical fibre as well as its cable. The fibre has zero-dispersion wavelength around 1310 nm as per how it was designed, however it can also be used in the 1550 nm wavelength region.<ref>{{Cite book|url=https://books.google.com/books?id=5LMp7yxfeDAC&pg=PA71|title=Optical Network Design and Implementation|last=Alwayn|first=Vivek|date=2004|publisher=Cisco Press|year=|isbn=9781587051050|location=|pages=71|language=en}}</ref>
