Media Converter
Media Converter covers small boxes that join copper Ethernet to fiber: TP-Link's MC210CS single-mode and MC220L SFP-based converters, Allied Telesis units including PoE+ models, and Transition Networks Fast Ethernet converters for older links. They're how you stretch a network beyond copper's 100-meter limit or connect a device without a fiber port to a fiber run. Matching the fiber type, wavelength and speed on both ends is what makes the link come up.

Buying guide
Building a fiber link with converters
Fixed or SFP-based
Fixed converters have the optic built in; SFP-based converters take a module, so you can choose single-mode or multi-mode later.
Matching pairs
Both ends need the same speed and fiber type. Single-fiber (BiDi) converters come in A and B pairs that use opposite wavelengths.
PoE converters
PoE+ models like Allied Telesis' AT-PC2000 can power a camera or access point at the far end of a fiber run.

Frequently asked questions
Why won't my two media converters link up?
The usual causes are mismatched fiber type (single-mode versus multi-mode), mismatched speeds, swapped transmit and receive strands, or a BiDi pair that isn't an A-and-B set.
Can a media converter replace a switch?
No. It converts one copper port to one fiber port. To connect several devices you still need a switch.
