Media converters link a copper Ethernet port (RJ-45) to a fibre-optic line. Use them when a run is longer than the 100 m limit of copper cable, when you need to connect two buildings, or when cabling passes near electrical interference. Models from PLANET, StarTech.com, Digitus, LevelOne, Intellinet and TRENDnet, in Fast Ethernet, Gigabit and 10G, with fixed fibre ports or an SFP slot.
How to choose the right media converter
- Match the fibre type. Single-mode (usually yellow cable, OS2) is for long distances, often several km. Multimode (OM3/OM4, aqua) is for shorter runs inside a building or campus. A single-mode converter will not work on multimode fibre, and the reverse.
- Match the connector. Check whether your fibre ends in SC, LC or ST and choose the same, or plan a patch cord to convert.
- Fixed port or SFP slot. Fixed models are ready to use. SFP models need a separate SFP module, which must match the speed, fibre type and distance you need.
- Speed. Fast Ethernet (100 Mb) is enough for cameras and basic links. Gigabit is the normal choice today. 10G is for links between servers and core switches.
- They work in pairs. You need one converter at each end of the fibre, or one converter connected to a switch that has a matching SFP or fibre port.
- Single-fibre (WDM/BiDi) models use one fibre strand instead of two, and must be bought as a matched A/B pair.
- PoE models also power a camera, access point or phone at the copper end, so you do not need a separate power supply there.
- Managed models and chassis. Managed converters can be monitored remotely. Rack chassis hold many converters in one 19" unit with shared power.
