    ORDERING INFORMATION

    ABSTRACT: This document sets forth the Telcordia view of generic requirements to applicable to unfilled (aircore) or filled,
    polyolefin-insulated-conductor (PIC) cables of up to 4200 pair counts with various shield and jacket constructions. GR-421 covers
    cables deployed from the cable entrance facility (CEF) or cable vault of the central office (CO) facility to the demarcation point at
    the customer premises with the exemption of service drop wires. The variety of cable products covered in this document may be deployed
    in aerial, underground and direct-buried plant applications where conditions can vary widely. This document covers mechanical and
    electrical generic requirements for polyofefin insulated telecommunications cables. It is organized into sections covering insulated
    conductors, core assembly and construction, shield construction, jackets, and performance requirements for the completed cable.

    GR-421 has been the primary requirements document for outside plant (OSP) exchange cables used in OSP applications - buried, aerial,
    and underground applications.

    Issue 2 of GR-421 was developed with industry input from service providers and suppliers, and includes:
    • Revisions to the latest insulation, jacket, and shield-material technologies, and other cable design changes

    • Updates to the latest cable, insulation, jacket and shield-material design technologies

    • Harmonization, where possible, of the document requirements with other industry specifications

    • Consolidation of a variety of product documents into a single GR document

    • An updated Section 10 to delete obsolete cable designs and references to pulp insulated wires, and introduce requirements for
      transition stub cables

    This document replaces GR-102, TR-NWT-000421, TR-TSY-000100, TR-TSY-000101, TR-TSY-000106, TR-TSY-000107, TR-TSY-000109, TR-TSY-000112,
    TR-TSY-000113, TR-TSY-000114, TR-TSY-000118, and TR-TSY-000119.

    Issue 2 of GR-421, Generic Requirements for Metallic Telecommunications Cables, replaces Issue 1. When using GR-421, you may
    want to refer to TR-TSY-000103, TR-TSY-000104, TR-TSY-000105, GR-115, GR-110, and GR-111, as well as various
