ABSTRACT: This Generic Requirements (GR) document sets forth the Telcordia view of proposed generic technical requirements and characteristics
required of fiber optic splice closures. It is Telcordia's view that these requirements be met in order to meet the needs of a Service
This document provides criteria for analyzing fiber optic splice closures used in a variety of outside plant (OSP) environments and
applications, including those used in building entrance facilities. Included in this document are proposed functional design criteria,
generic mechanical and environmental requirements, desired features, and the performance tests for comparing fiber optic splice
closures with the stated requirements. In many cases, the requirements contained in this document are specific to certain closure
applications. Organization of these requirements is such that application-specific requirements are identified separately from
requirements that are common to all closures. This departure from a UNIVERSAL set of requirements represents the most substantial
change to this document. It is intended to permit splice closures designed for specific applications to be available at lower cost than
"universal" closures. The performance tests for analyzing fiber optic splice closures are intended to reflect a composite picture of
standard installation and operating conditions.
GR-771 is the one document that contains all the general, electrical, mechanical and environmental requirements for fiber optic
slice closure products. This document is referred to by major service providers as the base requirements for these products.
Requirements and test methods are contained in this GR document.
Issue 2 of GR-771:
The following documents were fully or partly replaced by GR-771: TR-NWT-000771, TA-NWT-000771, TR-TSY-000005, TR-TSY-000262,
TA-TSY-000265, TA-NWT-001368, and TA-633-23343-84-01.
- A broadened scope to cover both fiber optic splice closures and terminals
- Inclusion of optical monitoring for mechanical and environmental tests
- New procedures and test methods
- Updates and changes to mechanical and environmental test procedures and test sequences
- Application-specific requirements are identified separately from requirements that are common to all closures. This is intended to
permit splice closures designed for specific applications to be available at lower cost than "universal" closures.
When using GR-771, you may need to refer to GR-63, GR-454, GR-839, GR-20, GR-2759, TR-TSY-000103,
GR-409, GR-769, TR-TSY-000843, TR-NWT-001001, TR-NWT-001121, TR-NWT-001322, UL 94, and several ASTM test
specifications. You may also want to refer to GR-1380.
