Generic Requirements for Hardened Fiber Optic Connectors (HFOCs) and Hardened Fiber Optic Adapters (HFOAs)
Document Number GR-3120
Issue Number 02
Issue Date Apr 2010
ABSTRACT: Hardened Fiber Optic Connectors (HFOCs) and Hardened Fiber Optic Adapters (HFOAs) are passive telecommunications components used in an
Outside Plant (OSP) environment. They provide drop connections to customers from fiber distribution networks. These components may be
provided in pedestal closures, aerial and buried closures and terminals, or equipment located at customer premises such as a Fiber
Distribution Hub (FDH) or an Optical Network Terminal or Termination (ONT) unit.
These connectors, which are field-mateable, and hardened for use in the outside plant (OSP), are needed to support Fiber to the
Premises (FTTP) deployment and service offerings.
Issue 2 of GR-3120:
