"Ethernet over Fibre is a networking technology that utilises fibre-optic cables to transmit Ethernet signals for high-speed data transfer and connectivity. Fibre optic cables are made of thin strands of glass or plastic that transmit data using light signals. In security applications, key advantages include: Long distances without signal loss Immunity to electromagnetic interference However, fibre optic cabling solutions also have a couple of disadvantages: They cannot transmit power, so POE delivery is not possible Cable installation and termination requires a higher skill level Balancing these disadvantages with the considerable advantages of fibre optic technology is essential when considering its implementation in a specific project."
