GR 3123 CORE : ISSUE 1

Describes the Telcordia view of proposed generic requirements for Indoor Fiber Distribution Hubs (FDHs). These requirements are intended to provide a suitable environment for telecommunications companies' FDHs used in an indoor environment. An indoor FDH can be installed on a customer premise in a basement or 'telephone room' or in a service provider Controlled Environmental Vault (CEV). Any equipment house in these FDH cabinets is accessible to the craftsperson through surface-mounted or removable doors. An FDH is normally installed as a connection and demarcation point from different feeder networks, or between a feeder network and the distribution network. These FDHs are passive and do not contain active electronics of fiber optics.
