Optical-Electrical Hybrid Cable for Access Network (GDFH)

Hybrid optical-electrical cable combines optical signal transmission with power supply in one cable. It is widely used in scenarios such as 5G base station construction, communication networking in remote areas, interconnection of industrial IoT devices, security surveillance system cabling, low-voltage system integration in smart buildings, integrated communication and power supply for rail transit, remote communication for offshore wind power and oil/gas platforms, broadband coverage for rural revitalization, and emergency communication support. It meets the high-speed data transmission needs of equipment while eliminating the cost and hassle of laying separate power cables, and is especially suitable for scenarios without external power supply or with complex cabling, making it a key cable solution for efficient networking across multiple fields.
Applications
  • Mainly used in DC remote power supply systems or areas where power is not readily available.
  • Solves the communication and power supply problems of FTTH or mobile communication network terminal equipment.
  • Integrates optical fiber and electrical cable in one, enabling simultaneous transmission of optical and electrical signals.
  • Widely used in communication and data transmission fields, meeting various signal transmission requirements with high-speed, stable, and reliable signal transmission.
