Generic Requirements for Single-Mode Optical Connectors and Jumper Assemblies
Document Number GR-326
Issue Number 04
Issue Date Feb 2010
Replaces TR-NWT-000326 Issue03
ABSTRACT: This Generic Requirements (GR) document sets forth the Telcordia view of the technical generic requirements for, and characteristics
required of, connectors used for joining singlemode optical fibers, and for the jumper assemblies made using such connectors. The
Telcordia view represents the expressed needs of the Telcordia Technical Forum (TTF) companies participating in the development of
these generic requirements (see Preface), and may meet the needs of other telecommunications service providers. It should be noted that
a user may have actual requirements that differ from the generic criteria contained in this document.
This GR includes the Telcordia view of the various requirements, desired features, and characteristics of connectors and jumper
assemblies, and the performance tests for comparing such products against the stated criteria.
The performance tests for analyzing optical connectors and jumper assemblies are intended to reflect a composite picture of various
operating conditions. The generic requirements, objectives, conditional requirements, and test methods are subject to change.
GR-326 is regarded as the most complete and rigorous standard for singlemode fiber-optic connectors. Issue 4 defines the latest
requirements required of connectors used for joining singlemode optical fibers and for jumper assemblies made using such connectors.
Issue 4 of GR-326:
The criteria provides the manufacturer with a basis for quality control and crucial information for quality assurance to guarantee
long-term performance in the field.
- Discusses endface geometry of singlemode connectors
- Contains new and updated criteria for singlemode connector reflectance
- Contains further detail regarding evaluation of samples after salt spray exposure
- Contains additional text that addresses similar products and factory considerations as it relates to present-day
This document replaces TA-NWT-000326 and TR-NWT-000326.
Issue 4 of GR-326, Generic Requirements for Singlemode Optical Connectors and Jumper Assemblies, replaces Issue 3.
When using GR-326, you may need to refer to GR-20, GR-63, GR-78, GR-253, GR-357, GR-409, GR-449,
GR-454, GR-765, GR-1081, GR-1221, GR-1435, GR-2919, and GR-2923 and various industry standards.
