Utility Communications OPTIF for FOX515/512

IEEE C37.94communication interface

One of the most important applications used by any power utility is protection of high voltage power lines.Protection relays,which provide the protection functionality for power lines,need to exchange information in order to ensure correct operation.The utility's captive communications network is normally used to provide reliable communications channels for protection applications.Such communications channels

Management System

The FOX515with a variety of services are managed centrally and accelerate the circuit provisioning process with only one element manager for all service types.

Applications with OPTIF

FOX515collects all utility specific signals and transmits the or copper interfaces.Therefore the FOX515provides standard data interfaces and utility specific interfaces such as the OPTIF module which provides up to four ports for differential protection signal transmission.
