Rec. ITU-T G.652 (11/2009) i

Recommendation ITU-T G.652

Characteristics of a single-mode optical fibre and cable

Summary

Recommendation ITU-T G.652 describes the geometrical, mechanical and transmission attributes of

a single-mode optical fibre and cable which has zero-dispersion wavelength around 1310 nm. The

ITU-T G.652 fibre was originally optimized for use in the 1310 nm wavelength region, but can also

be used in the 1550 nm region. This is the latest revision of a Recommendation that was first created

in 1984 and deals with some relatively minor modifications. This revision is intended to maintain the

continuing commercial success of this fibre in the evolving world of high-performance optical

transmission systems.

History

Version Approval date

Version 1 (10/1984)

Version 2 (11/1988)

Version 3 (03/1993)

Version 4 (04/1997)

Version 5 (10/2000) This revision includes the addition of tables for different levels of system support.

Version 6 (03/2003) This revision clarified the nomenclature for the different categories or fibre. Also, in

accordance with the agreement on spectral band description, the upper limit of the

L-band is changed from 16XX to 1625 nm. The attenuation characteristics for reduced

water peak categories, (G.652.C and G.652.D) are generalized to a broad region from a

single wavelength. PMD requirements are added for all categories and two categories

have reduced limits (compared to 0.5 ps/ km ). For the macrobending test, mandrel

diameter is reduced to 30 mm radius. As seen above, this Recommendation has

evolved considerably over the years; therefore the reader is warned to consider the

appropriate version to determine the characteristics of already deployed product,

taking into account the year of production. In fact, products are expected to comply

with the Recommendation that was in force at the time of their manufacture, but may

not fully comply with subsequent versions of the Recommendation.

Version 7 (06/2005) Support of G.695 applications is noted.

A clarification of the method of fitting chromatic dispersion coefficient values and

their use is provided in 5.10, along with some text on use of the statistics of chromatic

dispersion for system design.

A clarification of the relationship of the PMDQ of uncabled fibre to cabled fibre is

provided in 6.2.

In the tables of requirements:

The uncabled fibre PMD line item is removed from the tables and the note on the

requirement for uncabled fibre PMD is modified.

The tolerance of MFD at 1310 nm is reduced.

The maximum dispersion slope at the zero dispersion wavelength is reduced.

The maximum concentricity error is reduced.

The maximum macrobending loss is reduced.

The wording for the water peak requirement in Tables 3 and 4 are modified to reflect a

reference to the specification over the range vs the specification at 1310 nm.

摘要：

ITU-T G.652-2009 是国际电信联盟标准化部门制定的关于单模光纤与光缆特性的技术规范，主要定义了适用于传统1310nm和1550nm传输窗口的标准单模光纤的性能指标、几何参数以及测试方法。该标准详细规定了光纤的模场直径、截止波长、衰减系数、色散特性及光缆的机械与环境性能要求，为全球光纤通信网络的设计、生产与部署提供了统一的基准参考。遵循 G.652 标准的光纤广泛应用于长距离骨干网、城域网及接入网，是当前光通信基础设施中最基础且应用最广的光纤类型之一，确保系统在不同制造商产品间的互操
