AFL EMEA's OPGW (Optical Ground Wire) fibre optic cables, designed for aerial installations in telecom, energy, and utility networks. Offering robust performance and protection in harsh environments. Fibres are placed in a. OPGWatch® monitoring system detects events in real time across the overhead lines using only one fibre from installed OPGW cable. Application OPGW is mainly applied in communication line of newly constructed high voltage transmit electricity system with 35 KV or above, or replacement of existing ground wire of previous overhead high voltage transmit electricity system. OPGW is a dual functioning cable performing the duties of a ground wire and also providing a patch for the transmission of voice, video or data signals.
