There are some terms and concepts we need to know when talking about optical fiber, I will try to put here the most essential things.
There are many different connectors, I list here the main ones you're supposed to see in the industry.
|LC : Lucent Connector, Little Connector or Local Connector.
Note : The standard for new installations. Switches and Fiber Optic Patch sides.
|SC : Subscriber connector, square connector or standard connector.
Note : Still common on the Fiber Optic Patch sides.
Note : Mainly present on older installations.
|Distance (1 Gbits)||275 m||550 m||550 m||550 m||550 m|
|Distance (10 Gbits)||33 m||82 m||300 m||400 m||400 m|
|Distance (40 Gbits / 100 Gbits)||Not Supported||Not Supported||100 m||150 m||150 m|
|Distance||10 km / 6 Miles||100 km / 62 Miles|
SFP for small form-factor pluggable is a compact, hot-pluggable network interface module. (source : https://en.wikipedia.org).
They have the same format as SFP but the speed can reach up to 10 Gbits.
