GR-1209-CORE Testing

Generic Requirements for Passive Optical Components

GR-1209-CORE specifies test requirements to qualify passive optical components. Both singlemode and multimode cables are applicable.

GR-1209-CORE testing covers a wide range of fiber optic components. Splitters, for example, are a common component tested against this document. Splitters can be used in fiber distribution hubs (FDH) or as an independent device to broadcast a signal to multiple ports. GR-1209-CORE better ensures that the splitter provides adequate optical signal to multiple outputs during operation. Splitters installed in a FDH must resist different weather conditions (if installed outdoor) and structural hazards such as GR-1221 Section 6.2.2 Vibration, EIA/TIA-455-14 Module Impact, etc (if installed indoor).
