Symbols

Media converter symbol

A media converter changes the physical medium of an Ethernet link from copper twisted pair to optical fibre, without routing or switching. Diagrams draw a box with a copper port on one side and a fibre port, often marked with a light arrow, on the other.

Drawing use: Schematic
Application: Installation & communications
Reference family: IEC

A distinction that matters

A network switch forwards traffic between many ports; a media converter only changes the medium on one link.

Fibre-optic link symbol

Fibre-optic links are drawn as a line carrying a fibre indication, such as a small loop, a wavy section or the tag FO, between the devices they connect. Network diagrams also show the fibre count and type, such as 12-core single-mode.

Drawing use: Schematic / GA
Application: Installation & communications
Reference family: IEC
Form evidence: Optical fibre link. IEC 60617 installation-plan style (architectural and topographical installation symbols); independently drawn, not certified IEC geometry or a database identifier.

A distinction that matters

A copper data cable has no isolation benefit; the fibre link isolates the two ends electrically.
